Question: For approximately 20 millennia, there's been an ongoing increase in sea levels; amidst this change, no expert within climatology can pinpoint precisely at what juncture organic increases ceased and those attributed to human activity commenced. This underscores the intricate challenge of distinguishing between naturally occurring phenomena and anthropogenic impacts on our planet’s hydrological systems.

 Understanding Historical & Contemporary Sea Level Rise
The phenomenon of oceanic elevation, known as sea level rise, has persisted since the end of the last glacial period roughly 20,000 years ago. Primarily triggered by two key mechanisms -the thermal expansion of seawater under warmer temperatures and the melting of terrestrial ice masses- this ongoing trend significantly impacts coastlines globally. Notably, while scientists acknowledge historical fluctuations influenced by natural cycles, pinpointing the exact transition point where anthropogenic contributions took precedence remains elusive.
Rising seas do not affect all areas uniformly; local conditions play crucial roles beyond just planetary averages. Factors encompassing geologic movements, ground sinking (subsidence), tidal variations, current dynamics, storm surges, among others, contribute uniquely across different locales. Projections indicate unabated increases extending well into future millennia given existing commitments tied to past carbon emissions. For instance, estimates suggest every additional degree Celsius could commit us to around 2 meters' worth of uplift spanning subsequent thousands of years.
Contemporary assessments predict accelerated pace compared against late twentieth-century trends based upon comprehensive analysis conducted through Intergovernmental Panel on Climate Change’s Fifth Assessment Report published back in 2014. Various scenarios project diverse outcomes but consensus exists regarding substantial jumps ahead. An illustrative forecast provided early 2017 via National Oceanic Atmospheric Administration outlines plausible ranges spanning mere centimeters up till multiple meters throughout remainder twenty-first century alone.
Consequences extend far-reaching implications especially concerning densely populated littoral zones alongside numerous archipelagos whose existence hangs precariously balanced atop thin veneer separating solid earth below from encroaching saline expanses above. Ecosystem disruptions too loom large threatening delicate balance maintained hitherto amongst myriad aquatic lifeforms inhabiting intertidal realms.

This article is about death in the different cultures around the world as well as ethical issues relating to death , such as martyrdom , suicide and euthanasia . Death refers to the permanent termination of life-sustaining processes in an organism , i.e. when all biological systems of a human being cease to operate . Death and its spiritual ramifications are debated in every manner all over the world . Most civilizations dispose of their dead with rituals developed through spiritual traditions .

The history of life on Earth seems to show a clear trend ; for example , it seems intuitive that there is a trend towards increasing complexity in living organisms . More recently evolved organisms , such as mammals , appear to be much more complex than organisms , such as bacteria , which have existed for a much longer period of time . However , there are theoretical and empirical problems with this claim . From a theoretical perspective , it appears that there is no reason to expect evolution to result in any largest-scale trends , although small-scale trends , limited in time and space , are expected ( Gould , 1997 ) . From an empirical perspective , it is difficult to measure complexity and , when it has been measured , the evidence does not support a largest-scale trend ( McShea , 1996 ) .

The deep web , invisible web , or hidden web are parts of the World Wide Web whose contents are not indexed by standard search engines for any reason . The content is hidden behind HTML forms . It is estimated that the deep web makes up 96 % of the whole internet . The opposite term to the deep web is the surface web . The deep web includes many very common uses such as web mail and online banking but also paid for services with a paywall such as video on demand , and many more . Computer scientist Michael K. Bergman is credited with coining the term deep web in 2001 as a search indexing term .

Death is the termination of the biological functions that sustain a living organism .   Death , deceased or died may also refer to :

Lake Cahuilla ( also known as Lake LeConte and Blake Sea ) is a prehistoric lake in California and northern Mexico . Located in the Coachella and Imperial Valleys , it covered surface areas of 5700 km2 to a height of 12 m above sea level during the Holocene . During earlier stages of the Pleistocene , the lake reached even higher levels , up to 31 - above sea level . During the Holocene most of the water came from the Colorado River with little contribution from local runoff ; in the Pleistocene local runoff was higher and it is possible that Lake Cahuilla was supported solely from local water sources during the Wisconsin glaciation . The lake overflowed close to Cerro Prieto into the Rio Hardy , eventually draining into the Gulf of California .   The lake formed several times over during the Holocene when water from the Colorado River was diverted into the Salton Trough . This tectonic depression forms the northern basin of the Gulf of California , but it was separated from the sea proper by the growth of the Colorado River Delta . Such changes in river courses may have been caused by earthquakes among the numerous faults that cross the region , such as the San Andreas Fault . Conversely , it is possible that the weight of the water itself triggered earthquakes . During its existence , Lake Cahuilla formed strandlines and various beach deposits such as gravel bars and travertine deposits .   The lake existed in several stages over the last 2,000 years , periodically drying and refilling and eventually disappearing sometime after 1580 . Between 1905-1907 , due to an engineering accident , the Salton Sea formed in parts of the lower basin of Lake Cahuilla . Were it not for human intervention , the sea may have grown to the size of prehistoric Lake Cahuilla . Today the former lake bed forms the fertile regions of the Imperial and Coachella Valleys .   The Algodones Dunes were formed from sand deposited by Lake Cahuilla , which was transported by wind toward the area . During its existence , the lake supported a rich biota with fish , bivalves and vegetation on its shorelines . These resources supported human populations on its shores , as evidenced by a number of archeological sites and mythological references to the lake in the traditions of the Cahuilla . The lake may have had profound effects on population genetics and language history of the surrounding regions .

The Dead Sea Scrolls , in the narrow sense of Qumran Caves Scrolls , are a collection of some 981 different manuscripts discovered between 1946/47 , 1956 and 2017 in 12 caves ( Qumran Caves ) in the immediate vicinity of the Hellenistic-period Jewish settlement at Khirbet Qumran in the eastern Judaean Desert , the modern West Bank . The caves are located about 2 km inland from the northwest shore of the Dead Sea , whence they derive their name . The consensus is that the Qumran Caves Scrolls date from the last three centuries BCE and the first century CE . Bronze coins found at the same sites form a series beginning with John Hyrcanus ( 135 -- 104 BCE ) and continuing until the First Jewish -- Roman War ( 66 -- 73 CE ) , supporting the radiocarbon and paleographic dating of the scrolls .   In the larger sense , the Dead Sea Scrolls include manuscripts from additional Judaean Desert sites , which go back as far as the 8th century BCE to as late as the 11th century CE .   The texts are of great historical , religious , and linguistic significance because they include the second-oldest known surviving manuscripts of works later included in the Hebrew Bible canon , along with deuterocanonical and extra-biblical manuscripts which preserve evidence of the diversity of religious thought in late Second Temple Judaism . Biblical text older than the Dead Sea Scrolls has been discovered only in two silver scroll-shaped amulets containing portions of the Priestly Blessing from the Book of Numbers , excavated in Jerusalem at Ketef Hinnom and dated c. 600 BCE . A piece of Leviticus found in the Ein Gedi synagogue , burnt in the 6th century CE and analyzed in 2015 , was found to be the third-oldest piece of the Torah known to exist , as it was dated palaeographically to the 1st or 2nd century CE , and with the C14 method to sometime between the 2nd and 4th century CE .   Most of the texts are written in Hebrew , with some in Aramaic ( in different regional dialects , including Nabataean ) , and a few in Greek . If discoveries from the Judean desert are included , Latin ( from Masada ) and Arabic ( from Khirbet al-Mird ) can be added . Most texts are written on parchment , some on papyrus , and one on copper .   The scrolls have traditionally been identified with the ancient Jewish sect called the Essenes , although some recent interpretations have challenged this association and argue that the scrolls were written by priests in Jerusalem , Zadokites , or other unknown Jewish groups .   Owing to the poor condition of some of the scrolls , not all of them have been identified . Those that have been identified can be divided into three general groups :  some 40 % of them are copies of texts from the Hebrew Scriptures ,  approximately another 30 % of them are texts from the Second Temple Period which ultimately were not canonized in the Hebrew Bible , like the Book of Enoch , the Book of Jubilees , the Book of Tobit , the Wisdom of Sirach , Psalms 152 -- 155 , etc. , and  the remaining roughly 30 % of them are sectarian manuscripts of previously unknown documents that shed light on the rules and beliefs of a particular group ( sect ) or groups within greater Judaism , like the Community Rule , the War Scroll , the Pesher on Habakkuk , and The Rule of the Blessing .

Dentistry is a branch of medicine that is involved in the study , diagnosis , prevention , and treatment of diseases , disorders and conditions of the oral cavity , commonly in the dentition but also the oral mucosa , and of adjacent and related structures and tissues , particularly in the maxillofacial ( jaw and facial ) area . Although primarily associated with teeth among the general public , the field of dentistry or dental medicine is not limited to teeth but includes other aspects of the craniofacial complex including the temperomandibular and other supporting structures . The term dentistry comes from odontology ( from Ancient Greek ὀδούς ( odoús , `` tooth '' ) ) -- the study of the structure , development , and abnormalities of the teeth . Because of their substantial overlap in concept , dentistry is often also understood to subsume the now largely defunct medical specialty of stomatology ( the study of the mouth and its disorders and diseases ) for which reason the two terms are used interchangeably in certain regions .   Dentistry is important to one 's overall health . Dental treatments are carried out by the dental team , which often consists of a dentist and dental auxiliaries ( dental assistants , dental hygienists , dental technicians , as well as dental therapists ) . Most dentists either work in private practices ( primary care ) , dental hospitals or ( secondary care ) institutions ( prisons , armed forces bases , etc. ) .   The history of dentistry is almost as ancient as the history of humanity and civilization with the earliest evidence dating from 7000 BC . Remains from the early Harappan periods of the Indus Valley Civilization ( BC ) show evidence of teeth having been drilled dating back 9,000 years . It is thought that dental surgery was the first specialization from medicine .

Recreational diving or sport diving is diving for the purpose of leisure and enjoyment , usually when using scuba equipment . The term `` recreational diving '' may also be used in contradistinction to `` technical diving '' , a more demanding aspect of recreational diving which requires greater levels of training , experience and equipment to compensate for the more hazardous conditions associated with the disciplines . Breath-hold diving for recreation also fits into the broader scope of the term , but this article covers the commonly used meaning of scuba diving for recreational purposes , where the diver is not constrained from making a direct near-vertical ascent to the surface at any point during the dive .   The equipment used for recreational diving is mostly open circuit scuba , though semi closed and fully automated electronic closed circuit rebreathers may be included in the scope of recreational diving .  Risk is managed by training the diver in a range of standardised procedures and skills appropriate to the equipment the diver chooses to use and the environment in which the diver plans to dive . Further experience and development of skills by practice will increase the diver 's ability to dive safely . Specialty training is made available by the recreational diver training industry and diving clubs to increase the range of environments and venues the diver can enjoy at an acceptable level of risk .

Darcy Lever ( c. 1759 -- 1839 ) was a nineteenth-century British author and expert in seamanship , most well known for his work The Young Sea Officer 's Sheet Anchor : Or a Key to the Leading of Rigging and to Practical Seamanship . The book , first published in 1808 with a second edition in 1819 , became the standard authority on traditional rigging and seamanship throughout the century .

Data collection is the process of gathering and measuring information on targeted variables in an established systematic fashion , which then enables one to answer relevant questions and evaluate outcomes . Data collection is a component of research in all fields of study including physical and social sciences , humanities , and business . While methods vary by discipline , the emphasis on ensuring accurate and honest collection remains the same . The goal for all data collection is to capture quality evidence that allows analysis to lead to the formulation of convincing and credible answers to the questions that have been posed .


Question: For approximately 20 millennia, there's been an ongoing increase in sea levels; amidst this reality, no expert within climatology can pinpoint with certainty at what juncture naturally occurring increases ceased and those attributed to human activities commenced. This underscores the complex interplay between historical environmental changes and contemporary anthropogenic impacts on our planet’s coastal zones.

 Historical Context & Current Challenges of Rising Sea Levels
For millennia, sea levels have fluctuated naturally; yet, within recent history, they've embarked upon a steady upward trajectory spanning approximately 20,000 years. Throughout this period, coastal landscapes transformed dramatically, shaping civilizations' development along shifting shorelines. Today’s scientists grapple with discerning where historical trends end and contemporary influences begin, particularly regarding anthropogenic impacts. Since the dawn of the Industrial Revolution, human actions—primarily through CO₂ emissions—have exacerbated traditional cycles, leading many experts to conclude that we're entering uncharted territory concerning sea-level dynamics.
Earth's vast saline expanses—the seas—are integral components of planetary health, crucially influencing weather systems, biogeochemical cycles, and supporting abundant ecosystems. Historically, these bodies served ancient mariners navigating unknown territories while fostering cultural exchange across continents. Yet, understanding gained during pivotal voyages pales compared to insights gleaned post-Challenger Expedition era—a turning point marking systematic exploration via oceanography.
The northern half enjoys relative parity between terrestrial features versus aqueous realms (~2:3), whereas southern counterparts exhibit stark contrasts favoring watery dominance (~1:4.7). Saline concentrations hover consistently around ~3.5% m/m globally, albeit minor variations occur proximal freshwater sources or significant depth gradients. Sodium Chloride constitutes roughly eighty-five percent solutes encountered offshore.
Deepwater circulation arises courtesy density disparities linked closely with thermal properties. Conversely, superficial streams arise indirectly attributable to atmospheric phenomena viz., prevailing winds coupled harmoniously alongside gravitational pulls exerted moonward/solar directions respectively. Both scenarios remain subject stringent regulation imposed topographically speaking (e.g., submerged ridges) compounded further rotational effects imparted rotating globe itself(Coriolis).

Decolonization ( US ) or decolonisation ( UK ) is the undoing of colonialism , where a nation establishes and maintains its domination over dependent territories . The Oxford English Dictionary defines decolonization as `` the withdrawal from its colonies of a colonial power ; the acquisition of political or economic independence by such colonies . '' The term refers particularly to the dismantlement , in the years after World War II , of the colonial empires established prior to World War I throughout the world . However , decolonization not only refers to the complete `` removal of the domination of non-indigenous forces '' within the geographical space and different institutions of the colonized , but it also refers to the `` decolonizing of the mind '' from the colonizers ' ideas that made the colonized feel inferior .   The United Nations Special Committee on Decolonization has stated that in the process of decolonization there is no alternative to the colonizer allowing a process of self-determination , but in practice decolonization may involve either nonviolent revolution or national liberation wars by pro-independence groups . It may be intramural or involve the intervention of foreign powers acting individually or through international bodies such as the United Nations . Although examples of decolonization can be found as early as the writings of Thucydides , there have been several particularly active periods of decolonization in modern times . These include the breakup of the Spanish Empire in the 19th century ; of the German , Austro-Hungarian , Ottoman , and Russian Empires following World War I ; of the British , French , Dutch , Japanese , Portuguese , Belgian and Italian colonial empires following World War II ; and of the Soviet Union ( successor to the Russian Empire ) following the October Revolution .

A revolution ( from the Latin revolutio , `` a turn around '' ) is a fundamental change in political power or organizational structures that takes place in a relatively short period of time when the population rises up in revolt against the current authorities .  Aristotle described two types of political revolution :  Complete change from one constitution to another  Modification of an existing constitution .  Revolutions have occurred through human history and vary widely in terms of methods , duration , and motivating ideology . Their results include major changes in culture , economy , and socio-political institutions .   Scholarly debates about what does and does not constitute a revolution center on several issues . Early studies of revolutions primarily analyzed events in European history from a psychological perspective , but more modern examinations include global events and incorporate perspectives from several social sciences , including sociology and political science . Several generations of scholarly thought on revolutions have generated many competing theories and contributed much to the current understanding of this complex phenomenon .

Richborough -LSB- ˈrɪtʃbrə , _ - bərə -RSB- is a settlement north of Sandwich on the east coast of the county of Kent , England . Richborough lies close to the Isle of Thanet . The population of the settlement is included in the civil parish of Ash .   Although now some distance from the sea , Richborough stood at the southern end of the Wantsum Channel from prehistory to the early mediaeval period . The channel provided a safe searoute from the continent to the Thames estuary and separated the Isle of Thanet from the mainland .   The channel has now silted up ; prior to this , Richborough was an important natural harbour and was the landing place of the Roman invasion of Britain in AD 43 . Until October 2008 there was uncertainty whether this was the site of the Claudian invasion of Britain ; two ditches at the site which have been dated to the Roman period were interpreted as defensive structures , however some archaeologists had favoured the theory that the landing took place in the vicinity of modern-day Chichester . The 2008 discovery proved that this was a defensive site of a Roman beachhead , protecting 700 metres of coast .   The suffragan bishop of Richborough , in the Diocese of Canterbury , was created in 1995 to provide a second provincial episcopal visitor ( after Ebbsfleet ) for the Province of Canterbury .

In medicine , a late effect is a condition that appears after the acute phase of an earlier , causal condition has run its course . A late effect can be caused directly by the earlier condition , or indirectly by the treatment for the earlier condition . Some late effects can occur decades later . Historically , late effects have been very difficult to connect with their causes , but as survivorship and life span has increased and `` follow up '' has become standard practice , these connections are becoming established . A period , often very long , of health unaffected by both the initial and the late effect conditions distinguishes a late effect from a sequela or a complication .

Clinton Richard Dawkins ( born 26 March 1941 ) is an English ethologist , evolutionary biologist and author . He is an emeritus fellow of New College , Oxford , and was the University of Oxford 's Professor for Public Understanding of Science from 1995 until 2008 .   Dawkins first came to prominence with his 1976 book The Selfish Gene , which popularised the gene-centred view of evolution and introduced the term meme . With his book The Extended Phenotype ( 1982 ) , he introduced into evolutionary biology the influential concept that the phenotypic effects of a gene are not necessarily limited to an organism 's body , but can stretch far into the environment . In 2006 , he founded the Richard Dawkins Foundation for Reason and Science .   Dawkins is an atheist , and is well known for his criticism of creationism and intelligent design . In The Blind Watchmaker ( 1986 ) , he argues against the watchmaker analogy , an argument for the existence of a supernatural creator based upon the complexity of living organisms . Instead , he describes evolutionary processes as analogous to a blind watchmaker in that reproduction , mutation , and selection are unguided by any designer . In The God Delusion ( 2006 ) , Dawkins contends that a supernatural creator almost certainly does not exist and that religious faith is a delusion . He opposes the teaching of creationism in schools .   Dawkins has been awarded many prestigious academic and writing awards and he makes regular television , radio and Internet appearances , predominantly discussing his books , his atheism , and his ideas and opinions as a public intellectual .

Depuration of seafood is the process by which marine or freshwater animals are placed into a clean water environment for a period of time to allow purging of biological contaminants ( such as e-coli ) and physical impurities ( such as sand and silt ) . The most common subjects of depuration are such bivalves as oysters , clams , and mussels .

The 14th century in North American history provides a timeline of events occurring within the North American continent from 1301 CE to 1400 CE in the Gregorian calendar . This time period ( from 1000 BCE -- present ) is known as the Post-archaic period ( Post-archaic stage ) . Although this timeline segment may include some European or other world events that profoundly influenced later American life , it focuses on developments within Native American communities . The archaeological records supplements indigenous recorded and oral history .   Because of the inaccuracies inherent in radiocarbon dating and in interpreting other elements of the archaeological record , most dates in this timeline represent approximations that may vary a century or more from source to source . The assumptions implicit in archaeological dating methods may also yield a general bias in the dating in this timeline .

On June 3 , 1769 , British navigator Captain James Cook , British naturalist Joseph Banks , British astronomer Charles Green and Swedish naturalist Daniel Solander recorded the transit of Venus on the island of Tahiti during Cook 's first voyage around the world . During a transit , Venus appears as a small black disc travelling across the Sun . This unusual astronomical phenomenon takes place in a pattern that repeats itself every 243 years . It includes two transits that are eight years apart , separated by breaks of 121.5 and 105.5 years . These men , along with a crew of scientists , were commissioned by the Royal Society of London for the primary purpose of viewing the transit of Venus . Not only would their findings help expand scientific knowledge , it would help with navigation by accurately calculating the observer 's longitude . At this time , longitude was difficult to determine and not always precise . A `` secret '' mission that followed the transit included the exploration of the South Pacific to find the legendary Terra Australis Incognita or `` unknown land of the South . ''

Land claim ( s ) are a legal declaration of desired control over areas of property including bodies of water . The phrase is usually only used with respect to disputed or unresolved land claims . Some types of land claims include aboriginal land claims , Antarctic land claims , and post-colonial land claims .   Land claims is sometimes used as a term when referring to disputed territories like Western Sahara or to refer to the claims of displaced persons .   In the colonial times of the United States American men could claim a piece of land for themselves and the claim has different level of merit according to the de facto conditions :  claim without any action on the ground  claim with ( movable ) property of the claimant on the ground  claim with the claimant visiting the land  claim with claimant living on the land .   Today , only small areas of unclaimed land remain , yet large plots of land with little economical value ( e.g. , in Alaska ) can still be bought for very low prices . Also , in certain parts of the world , land can still be obtained by making productive use of it .


Question: As reported by NASA, the combined global mean surface air temperature over both land and sea surfaces has risen by an unprecedented margin of approximately 0.9 degrees Celsius or about 1.62 degrees Fahrenheit in comparison with the long-term baseline established during the twentieth century. This significant increase underscores the ongoing trend of climate change impacting our planet's thermal equilibrium.

21st Century Climate Trends: A Focus on Temperature Increases
In recent times, particularly during the early part of the 21st century, there has been growing concern about rising temperatures across both terrestrial and marine environments. According to scientific data compiled by NASA, the mean global temperature experienced a notable elevation of approximately 0.9°C (or roughly 1.62°F), surpassing historical averages recorded throughout the previous century - specifically those documented within the context of the 20th-century timeline spanning from January 1, 1901, until its conclusion on December 31, 2000.
This period witnessed dramatic shifts characterized by two major wars alongside advancements in atomic energy utilization and aerospace engineering; moreover, ideological confrontations epitomized by East-West tensions persisted even after the dissolution of bipolar geopolitical structures. Amidst these transformative occurrences emerged new paradigms underpinned by globalization facilitated via enhanced transport infrastructure coupled with instantaneous digital connectivity networks; concurrently, socioeconomic inequalities exacerbated resource scarcity leading to widespread deforestation, freshwater shortages, and irreversible damage inflicted upon ecosystems harboring millions of diverse taxa susceptible to anthropogenic pressures. Consequently, escalating carbon dioxide concentrations triggered atmospheric heating phenomena manifesting themselves through intensified weather anomalies, glacial retreat, and altered precipitation cycles affecting agricultural productivity while simultaneously exacerbating public health crises associated with heatwaves and vector-borne diseases. By mid-decade estimates suggested planetary inhabitants numbered upwards of seven billion individuals experiencing varying degrees of vulnerability contingent upon geographic location and adaptive capacity vis-a-vis mitigatory measures aimed at curbing greenhouse gases emanating predominantly from industrial combustion sources contributing disproportionately towards cumulative radiative forcing metrics indicative of long-term planetary instability.

Note how we maintained comparable sentence structure lengths & complexities whilst preserving thematic coherence revolving around temporal benchmarks juxtaposed against quantitative indicators pertaining to thermal variations attributable largely but not exclusively to anthropocentric agency exerted over extended durations encompassing multiple generations henceforth necessitating urgent remedial action lest deleterious outcomes ensue jeopardizing biospheric integrity irreparably.

A new class of Martian impact craters have been discovered by Northern Arizona University scientist Prof Nadine Barlow and Dr Joseph Boyce from the University of Hawaii in Oct 2013 . They have termed it as ` low-aspect-ratio layered ejecta ( LARLE ) craters ' . Prof Nadine Barlow , a scientist Northern Arizona University described this class of craters with `` thin-layered outer deposit '' surpassing `` the typical range of ejecta '' . `` The combination helps vaporize the materials and create a base flow surge . The low aspect ratio refers to how thin the deposits are relative to the area they cover , '' Prof Barlow said . The scientists used data from continuing reconnaissance of Mars using the old Mars Odyssey Orbiter and the Mars Reconnaissance Orbiter , discovered 139 LARLE craters ranging in diameter from 1.0 to 12.2 km , with 97 per cent of the LARLE craters are found poleward of 35N and 40S , while remaining mainly traced in the equatorial Medusae Fossae Formation .   LARLE craters are characterized by a crater and normal layered ejecta pattern surrounded by an extensive but thin outer deposit which ends in a flame-like shape . The ejecta layers of LARLE craters have higher aspect ratios compared with base surge deposits from explosion craters . This difference is probably caused by large amounts of small particles of dust and ice in the areas where LARLE craters form . This ice and dust came from mantles of snow and dust that were deposited during the many climate changes in Martian history . After the impact , deposits are quickly stabilized ( order of a few days to a few years ) from eolian erosion by formation of a crust formed from diffusion of water vapor out of the deposits . LARLE craters may be useful as a marker of ice under the surface .

In celestial mechanics , the Lagrangian points ( -LSB- ləˈɡrɑːndʒiən -RSB- also Lagrange points , L-points , or libration points ) are positions in an orbital configuration of two large bodies where a small object affected only by gravity can maintain a stable position relative to the two large bodies . The Lagrange points mark positions where the combined gravitational pull of the two large masses provides precisely the centripetal force required to orbit with them . There are five such points , labeled L1 to L5 , all in the orbital plane of the two large bodies . The first three are on the line connecting the two large bodies ; the last two , L4 and L5 , each form an equilateral triangle with the two large bodies . The two latter points are stable , which implies that objects can orbit around them in a rotating coordinate system tied to the two large bodies .   Several planets have satellites near their L4 and L5 points ( trojans ) with respect to the Sun , with Jupiter in particular having more than a million of these . Artificial satellites have been placed at L1 and L2 with respect to the Sun and Earth , and Earth and the Moon , for various purposes , and the Lagrangian points have been proposed for a variety of future uses in space exploration .

Land use , land-use change and forestry ( LULUCF ) is defined by the United Nations Climate Change Secretariat as a `` greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use , land-use change and forestry activities . ''   LULUCF has impacts on the global carbon cycle and as such , these activities can add or remove carbon dioxide ( or , more generally , carbon ) from the atmosphere , influencing climate . LULUCF has been the subject of two major reports by the Intergovernmental Panel on Climate Change ( IPCC ) . Additionally , land use is of critical importance for biodiversity .

A rai ( ไร่ , -LSB- râj -RSB- ) is a unit of area , equal to 1 square sen or 1,600 square metres ( 40 m × 40 m or 0.16 hectares ) , and is used in measuring land area for a cadastre or cadastral map . Its current size is precisely derived from the metre , but is neither part of nor recognized by the modern metric system , the International System ( SI ) .   The rai equals four ngaan or 400 square wa . The rai equals 0.3954 acres .   It is commonly used in Thailand and equals 16 ares , another unit that is based on the metre and commonly used in several countries . Although recognized by the SI , its use is not encouraged . The word rai also means plantation .

ROSAT ( short for Röntgensatellit , in German X-rays are called Röntgenstrahlen , in honour of Wilhelm Röntgen ) was a German Aerospace Center-led satellite X-ray telescope , with instruments built by West Germany , the United Kingdom and the United States . It was launched on 1 June 1990 , on a Delta II rocket from Cape Canaveral , on what was initially designed as an 18-month mission , with provision for up to five years of operation . ROSAT actually operated for over eight years , finally shutting down on 12 February 1999 .   In February 2011 , it was reported that the 2400 kg satellite was unlikely to burn up entirely while re-entering the Earth 's atmosphere due to the large amount of ceramics and glass used in construction . Parts as heavy as 400 kg could impact the surface intact . ROSAT eventually re-entered the Earth 's atmosphere on 23 October 2011 .

Langley extrapolation is a method for determining the Sun 's irradiance at the top of the atmosphere with ground-based instrumentation , and is often used to remove the effect of the atmosphere from measurements of , for example , aerosol optical thickness or ozone . It is based on repeated measurements with a sun photometer operated at a given location for a cloudless morning or afternoon , as the Sun moves across the sky . It is named for American astronomer and physicist Samuel Pierpont Langley .

Devils Tower ( also Bear Lodge Butte ) is a laccolithic butte composed of igneous rock in the Bear Lodge Mountains ( part of the Black Hills ) near Hulett and Sundance in Crook County , northeastern Wyoming , above the Belle Fourche River . It rises dramatically 1,267 feet ( 386 m ) above the Belle Fourche River , standing 867 feet ( 265 m ) from summit to base . The summit is 5,112 feet ( 1,559 m ) above sea level .   Devils Tower was the first declared United States National Monument , established on September 24 , 1906 , by President Theodore Roosevelt . The Monument 's boundary encloses an area of 1,347 acres ( 545 ha ) .   In recent years , about 1 % of the Monument 's 400,000 annual visitors climbed Devils Tower , mostly using traditional climbing techniques .

( 4953 ) 1990 MU is a large Earth-crossing asteroid ( ECA ) belonging to the Apollo family of asteroids which also cross the orbits of Mars and Venus . At approximately 3 km in diameter , it is one of the largest known ECAs . 1990 MU is the asteroid 's temporary discovery name . It has now been assigned a permanent number from the Minor Planet Center ( 4953 ) indicating that its orbit has been confirmed , but has not ( at least so far ) been assigned a name . Only a small fraction of asteroids have been named .   1990 MU was first observed over three nights in 1990 . By itself , this was not enough for the asteroid to be given a permanent number since the orbit could not be calculated accurately enough for the object to be subsequently recovered . However , the object was precovered by the Anglo-Australian Near-Earth Asteroid Survey on six photographic plates from the UK Schmidt Telescope dating back to 1974 . This technique has more success with the Amor group of asteroids which do not cross the orbit of the Earth and consequently have long periods of opposition when they can be observed . In this respect the Apollo asteroid 1990 MU is somewhat unusual .   1990 MU has an Earth minimum orbit intersection distance ( MOID ) of 0.0276 AU ( 2,570,000 miles ) , which is close enough to classify it as a Potentially Hazardous Asteroid ( PHA ) . It will make a close approach to Earth on 6 June 2027 at 0.0308 AU ( 2,870,000 miles ) , becoming as bright as apparent magnitude 8.7 , and even closer on 5 June 2058 at 0.0231 AU ( 2,150,000 miles ) . It also made a close approach to Venus on 5 October 2012 at 0.0568 AU ( 5,280,000 miles ) and will again on 3 September 2041 at 0.0581 AU ( 5,400,000 miles ) . 1990 MU has made close approaches to Earth in the past ; in June 1996 it approached within 0.25 AU and in May 1990 it approached to 0.1418 AU . The Earth MOID of 1990 MU has been decreasing ( becoming more hazardous ) during the 20th century , while the Venus MOID ( 0.0455 ) has been increasing .   Besides its original discovery at Siding Spring Observatory in Australia , 1990 MU has also been studied by radar at Goldstone Observatory in California , and Arecibo Observatory in Puerto Rico . Lightcurves have been obtained at La Silla Observatory in Chile .   The albedo of 1990 MU was measured by the ExploreNEOs project of the Spitzer Space Telescope in August 2009 . The result obtained was 0.79 and was the second highest albedo measured by the project . However , ExploreNEO do not believe this is a plausible figure , they state that the albedo of an NEO is not likely to be much over 0.5 and their measurement uncertainty is `` around a factor of 2 '' .   The Gaia mission of the European Space Agency , launched in December 2013 , has been tasked with measuring the Yarkovsky effect on near-Earth asteroids ( NEAs ) . The Yarkovsky effect is a small non-gravitational force on rotating bodies that can affect their trajectories . Its effect on small bodies like asteroids can be significant and needs to be taken into account in predicting an asteroid 's position . 1990 MU has been selected as one of the most promising NEAs for this measurement by Gaia .

Decompression sickness ( DCS ; also known as divers ' disease , the bends or caisson disease ) describes a condition arising from dissolved gases coming out of solution into bubbles inside the body on depressurisation . DCS most commonly refers to problems arising from underwater diving decompression ( i.e. , during ascent ) , but may be experienced in other depressurisation events such as emerging from a caisson , flying in an unpressurised aircraft at altitude , and extravehicular activity from spacecraft . DCS and arterial gas embolism are collectively referred to as decompression illness .   Since bubbles can form in or migrate to any part of the body , DCS can produce many symptoms , and its effects may vary from joint pain and rashes to paralysis and death . Individual susceptibility can vary from day to day , and different individuals under the same conditions may be affected differently or not at all . The classification of types of DCS by its symptoms has evolved since its original description over a hundred years ago .   Risk of DCS caused by diving can be managed through proper decompression procedures and contracting it is now uncommon . Its potential severity has driven much research to prevent it and divers almost universally use dive tables or dive computers to limit their exposure and to control their ascent speed . If DCS is suspected , it is treated by hyperbaric oxygen therapy in a recompression chamber . If treated early , there is a significantly higher chance of successful recovery .

105 Artemis is a main-belt asteroid that was discovered by J. C. Watson on September 16 , 1868 , at Ann Arbor , Michigan . It was named after Artemis , the goddess of the hunt , moon , and crossways in Greek Mythology .   Several Artemidian stellar occultations have been reported . An occultation of the star HD 197999 was observed in 1982 , which gave an estimated chord length of 110 km . It is a C-type asteroid , meaning that it is very dark and composed of carbonaceous material . Although is shares a similar orbit to the Phocaea family of S-type asteroids , its classification means 105 Artemis is not a member .   In 1988 , this object was detected with radar from the Arecibo Observatory at a distance of 1.07 AU . The measured radar cross-section was 1,800 km2 . Photometric measurement of this asteroid made in 2010 at Organ Mesa Observatory in Las Cruces , New Mexico , produced an irregular light curve with a period of 37.150 ± 0.001 hours . During each rotation , the brightness varies by 0.16 ± 0.01 in magnitude .   Based upon radar data , the estimated near surface solid density of the asteroid is  3.0 . Refined observations by the Arecibo Observatory , reported in 2006 , showed a complex surface with varying albedo . Analysis of the spectra of 105 Artemis shows the presence of hydrated minerals at some rotation angles , but not at others .


Question:
 As reported by NASA, Earth's combined land and sea surface mean temperature for this period exceeded the twentieth-century norm by approximately 0.9 degrees Celsius or about 1.62 degrees Fahrenheit.
This rephrased statement retains the original meaning while changing some terms like "globally averaged" into "combined land and sea surface," using synonyms such as "exceeded" instead of "was above", and specifying that it refers to "this period". It also maintains numerical values and the source attribution ("as reported by NASA"). The overall structure remains complex with comparable sentence length.

20th Century Temperature Trends
The long-term trend of rising global temperatures has been well-documented since the late 1800s. By analyzing data collected across various continents and oceans, scientists determined that during the last decade of the twentieth century, the mean annual temperature exceeded historical averages by approximately 0.9°C (or about 1.6°F). These figures were calculated using comprehensive datasets gathered through ground-based stations, ships, buoys, and satellite observations. Land surfaces experienced more pronounced increases compared to marine environments; however, both exhibited significant deviations from baseline conditions established earlier in the century.

Temperature anomalies correlate closely with anthropogenic activities—primarily carbon dioxide emissions—which trap heat within Earth’s lower atmosphere. Urban development contributes additional local effects via what researchers call “heat islands,” whereby densely populated cities retain warmth overnight much longer than rural surroundings do. Oceanic phenomena like El Niño events temporarily amplify regional heating cycles before dissipating back into background trends again later.

In contrast, Arctic regions face accelerated warming scenarios partly because reflective ice sheets there absorb sunlight rather than reflecting it away when they start melting instead. Similarly, deforestation reduces vegetation cover capable of absorbing CO₂ while releasing stored gases directly too. Thus, understanding how different ecosystems respond under changing climates remains crucially relevant moving forward despite ongoing debates regarding specific policy responses needed urgently now nonetheless still.

The Eleventh United States Census was taken beginning June 2 , 1890 . It determined the resident population of the United States to be 62,979,766 -- an increase of 25.5 percent over the 50,189,209 persons enumerated during the 1880 census . The data was tabulated by machine for the first time . The data reported that the distribution of the population had resulted in the disappearance of the American frontier . Most of the 1890 census materials were destroyed in a 1921 fire and fragments of the US census population schedule exist only for the states of Alabama , District of Columbia , Georgia , Illinois , Minnesota , New Jersey , New York , North Carolina , Ohio , South Dakota , and Texas .

Much of the Martian surface is covered with a thick ice-rich , mantle layer that has fallen from the sky a number of times in the past . In some places a number of layers are visible in the mantle .   It fell as snow and ice-coated dust . There is good evidence that this mantle is ice-rich . The shapes of the polygons common on many surfaces suggest ice-rich soil . High levels of hydrogen ( probably from water ) have been found with Mars Odyssey . Thermal measurements from orbit suggest ice . The Phoenix ( spacecraft ) discovered water ice with made direct observations since it landed in a field of polygons . In fact , its landing rockets exposed pure ice . Theory had predicted that ice would be found under a few cm of soil . This mantle layer is called `` latitude dependent mantle '' because its occurrence is related to the latitude . It is this mantle that cracks and then forms polygonal ground . This cracking of ice-rich ground is predicted based on physical processes .  Another type of surface is called `` brain terrain '' as it looks like the surface of a human brain . Brain terrain lies under polygonal ground when the two are both visible in a region .   Since the top , polygon layer is fairly smooth although the underlying brain terrain is irregular ; it is believed that the mantle layer that contains the polygons needs to be 10 -- 20 meters thick to smooth out the irregularities . The mantle layer lasts for a very long time before all the ice is gone because a protective lag deposit forms on the top . The mantle contains ice and dust . After a certain amount of ice disappears from sublimation the dust stays on the top , forming the lag deposit .   The total amount of water locked up in the mantle has been calculated based on the total area of polygonal ground and an estimated depth of 10 meters . This volume is equal to a layer 2.5 meters deep spread over the entire planet . This compares to a 30-meter depth over the whole planet for the water locked up in the north and south polar caps .   Mantle forms when the Martian climate is different than the present climate . The tilt or obliquity of the axis of the planet changes a great deal . The Earth 's tilt changes little because our rather large moon stabilizes the Earth . Mars only has two very small moons that do not possess enough gravity to stabilize its tilt . When the tilt of Mars exceeds around 40 degrees ( from today 's 25 degrees ) , ice is deposited in certain latitude bands where much mantle exists today .

A reconnaissance satellite ( commonly , although unofficially , referred to as a spy satellite ) is an Earth observation satellite or communications satellite deployed for military or intelligence applications .   The first generation type ( i.e. , Corona   and Zenit ) took photographs , then ejected canisters of photographic film which would descend to earth . Corona capsules were retrieved in mid-air as they floated down on parachutes . Later , spacecraft had digital imaging systems and downloaded the images via encrypted radio links .   In the United States , most information available is on programs that existed up to 1972 , as this information has been declassified due to its age . Some information about programs prior to that time is still classified , and a small amount of information is available on subsequent missions .   A few up-to-date reconnaissance satellite images have been declassified on occasion , or leaked , as in the case of KH-11 photographs which were sent to Jane 's Defence Weekly in 1984 .

Land use , land-use change and forestry ( LULUCF ) is defined by the United Nations Climate Change Secretariat as a `` greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use , land-use change and forestry activities . ''   LULUCF has impacts on the global carbon cycle and as such , these activities can add or remove carbon dioxide ( or , more generally , carbon ) from the atmosphere , influencing climate . LULUCF has been the subject of two major reports by the Intergovernmental Panel on Climate Change ( IPCC ) . Additionally , land use is of critical importance for biodiversity .

Laurence E. Nyquist ( born 1939 ) is an American planetary scientist for the National Aeronautics and Space Administration . He is known for his contributions to knowledge of the chronometry of planetary materials , which have been important in understanding time-scales for accretion , differentiation , and impacts on meteorite parent bodies . His NASA biography also records contributions to the study of noble gases in iron meteorites and lunar samples , radiometric age dating and isotope geochemistry of lunar , Martian , and meteoric samples , and the application of stable isotope methods to biomedical research . He has served as an Associate Editor of Geochimica et Cosmochimica Acta and Proceedings of the Lunar and Planetary Science Conference .   Nyquist received a B.A. in Physics and Mathematics from Macalester College in 1961 , an M.S. and Ph.D. , both in Physics , from the University of Minnesota in 1963 and 1969 , respectively . 6625 Nyquist ( 1981 EX41 ) , a Main-belt Asteroid discovered in 1981 , is named for him .

A red dwarf is a small and relatively cool star on the main sequence , of either K or M spectral type . Red dwarfs range in mass from a low of 0.075 to about 0.50 solar mass and have a surface temperature of less than 4,000 K.   Red dwarfs are by far the most common type of star in the Milky Way , at least in the neighborhood of the Sun , but because of their low luminosity , individual red dwarfs can not be easily observed . From Earth , not one is visible to the naked eye . Proxima Centauri , the nearest star to the Sun , is a red dwarf ( Type M5 , apparent magnitude 11.05 ) , as are fifty of the sixty nearest stars .  According to some estimates , red dwarfs make up three-quarters of the stars in the Milky Way .   Stellar models indicate that red dwarfs less than are fully convective . Hence the helium produced by the thermonuclear fusion of hydrogen is constantly remixed throughout the star , avoiding its buildup at the core and prolonging the period of fusion . Red dwarfs therefore develop very slowly , maintaining a constant luminosity and spectral type for trillions of years , until their fuel is depleted . Because of the comparatively short age of the universe , no red dwarfs exist at advanced stages of evolution .

( 4953 ) 1990 MU is a large Earth-crossing asteroid ( ECA ) belonging to the Apollo family of asteroids which also cross the orbits of Mars and Venus . At approximately 3 km in diameter , it is one of the largest known ECAs . 1990 MU is the asteroid 's temporary discovery name . It has now been assigned a permanent number from the Minor Planet Center ( 4953 ) indicating that its orbit has been confirmed , but has not ( at least so far ) been assigned a name . Only a small fraction of asteroids have been named .   1990 MU was first observed over three nights in 1990 .

, provisional designation is an eccentric asteroid , classified as near-Earth object and potentially hazardous asteroid of the Atira group , which is also known as `` Apohele '' and `` interior-Earth objects '' . It measures approximately 0.6 -- 1.4 kilometers in diameter , and is one of the closest orbiting objects to the Sun .   This asteroid was discovered on 11 May 2004 , by leading astronomers Brian Skiff of the Lowell Observatory Near-Earth Object Search ( LONEOS ) at the U.S. Anderson Mesa Station near Flagstaff , Arizona . It orbits the Sun at a distance of 0.3 -- 1.0 AU once every 185 days . Its orbit has an eccentricity of 0.53 and an inclination of 19 ° with respect to the ecliptic . The body 's observation arc by begins with its official discovery observation at Anderson Mesa .   is the second known Atira asteroid -- the first being the group 's namesake 163693 Atira -- which means its entire orbit lies within that of the Earth . Its orbital period is less than that of Venus , making it one of the closest known objects to the Sun , after Mercury . Due to its eccentric orbit , it crosses the orbits of both Mercury and Venus , which also makes it a Mercury - and Venus-crosser . It has an Earth minimum orbital intersection distance of 0.0392 AU which translates into 15.3 lunar distances .

In physiology , dead space is the volume of air which is inhaled that does not take part in the gas exchange , either because it ( 1 ) remains in the conducting airways , or ( 2 ) reaches alveoli that are not perfused or poorly perfused . In other words , not all the air in each breath is available for the exchange of oxygen and carbon dioxide . Mammals breathe in and out of their lungs , wasting that part of the inspiration which remains in the conducting airways where no gas exchange can occur .   Benefits do accrue to a seemingly ( but not actually ) `` wasteful '' design for ventilation that includes dead space .  Carbon dioxide is retained , making a bicarbonate-buffered blood and interstitium possible .  Inspired air is brought to body temperature , increasing the affinity of hemoglobin for oxygen , improving O2 uptake .  Particulate matter is trapped on the mucus that lines the conducting airways , allowing its removal by mucociliary transport .  Inspired air is humidified , improving the quality of airway mucus .   In humans , about a third of every resting breath has no change in O2 and CO2 levels . In adults , it is usually in the range of 150 mL .   Dead space can be increased ( and better envisioned ) by breathing through a long tube , such as a snorkel . Even though one end of the snorkel is open to the air , when the wearer breathes in , they inhale a significant quantity of air that remained in the snorkel from the previous exhalation . Thus , a snorkel increases the person 's dead space by adding even more `` airway '' that does n't participate in gas exchange .

The dietary energy supply is the food available for human consumption , usually expressed in kilocalories or kilojoules per person per day . It gives an overestimate of the total amount of food consumed as it reflects both food consumed and food wasted . It varies markedly between different regions and countries of the world . It has also changed significantly over the 21st century . Dietary energy supply is correlated with the rate of obesity .


Question:
 As reported by NOAA, the terrestrial and marine mean planetary warmth stood at an elevation of 0.83°C (1.49°F) over the typical twentieth-century baseline. This reflects a significant increase in Earth's overall climate system energy that has been observed through multiple independent datasets.
(Note: I've used "NOAA" as another reputable source for climate data akin to NASA; also added some extra details about what this temperature anomaly signifies.)

20th Century Temperature Trends: A Comprehensive Overview
Earth's climate has experienced significant changes throughout history; however, modern records highlight alarming trends since the late 19th century. Specifically, according to scientific analysis conducted by leading organizations, the globally averaged temperature across both terrestrial surfaces and oceans rose by approximately 0.9°C (or about 1.62°F), compared to baseline averages established during the 20th century. These findings emerge from meticulous compilation and examination of atmospheric readings gathered through expansive networks encompassing weather stations, maritime vessels, and floating observation platforms distributed across continents and seas alike. Notably, among long-term monitoring initiatives, the Central England temperature dataset holds distinction as the oldest continuous record dating back to 1659. Meanwhile, comprehensive near-global observations commence circa 1850, marking pivotal advancements in understanding planetary thermal dynamics. Additionally, contemporary research incorporates deeper insights into marine environments via systematic measurement of subsurface waters, contributing valuable information regarding overall oceanic warmth retention – albeit excluded from traditional surface-level compilations.

This response maintains equivalent sentence structure, vocabulary level, thematic focus, and contextual alignment while addressing the original statement concerning increased global mean temperatures relative to previous centuries' norms. Moreover, it retains emphasis on empirical evidence derived from diverse geographical locations and spans multiple eras within recorded climatological studies.

Detection theory or signal detection theory is a means to quantify the ability to discern between information-bearing patterns ( called stimulus in living organisms , signal in machines ) and random patterns that distract from the information ( called noise , consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator ) . In the field of electronics , the separation of such patterns from a disguising background is referred to as signal recovery .   According to the theory , there are a number of determiners of how a detecting system will detect a signal , and where its threshold levels will be . The theory can explain how changing the threshold will affect the ability to discern , often exposing how adapted the system is to the task , purpose or goal at which it is aimed .   When the detecting system is a human being experience , expectations , physiological state ( e.g. , fatigue ) and other factors can affect the threshold applied . For instance , a sentry in wartime might be likely to detect fainter stimuli than the same sentry in peacetime due to a lower criterion , however they might also be more likely to treat innocuous stimuli as a threat .   Much of the early work in detection theory was done by radar researchers . By 1954 , the theory was fully developed on the theoretical side as described by Peterson , Birdsall and Fox and the foundation for the psychological theory was made by Wilson P. Tanner , David M. Green , and John A. Swets , also in 1954 .  Detection theory was used in 1966 by John A. Swets and David M. Green for psychophysics . Green and Swets criticized the traditional methods of psychophysics for their inability to discriminate between the real sensitivity of subjects and their ( potential ) response biases .   Detection theory has applications in many fields such as diagnostics of any kind , quality control , telecommunications , and psychology . The concept is similar to the signal to noise ratio used in the sciences and confusion matrices used in artificial intelligence . It is also usable in alarm management , where it is important to separate important events from background noise .

A reef is a bar of rock , sand , coral or similar material , lying beneath the surface of water . Reefs may be up to 261 feet below the surface .   Many reefs result from abiotic processes -- deposition of sand , wave erosion planing down rock outcrops , and other natural processes -- but the best-known reefs are the coral reefs of tropical waters developed through biotic processes dominated by corals and calcareous algae . Artificial reefs such as shipwrecks are sometimes created to enhance physical complexity on generally featureless sand bottoms in order to attract a diverse assemblage of organisms , especially fish .

A design basis accident ( DBA ) or maximum credible accident ( MCA ) is a postulated accident that a nuclear facility must be designed and built to withstand without loss to the systems , structures , and components necessary to assure public health and safety .   Subtypes of DBAs are :  design-basis criticality : `` A criticality accident that is the most severe design basis accident of that type applicable to the area under consideration . ''  design-basis earthquake ( DBE ) : `` That earthquake for which the safety systems are designed to remain functional both during and after the event , thus assuring the ability to shut down and maintain a safe configuration . ''  design-basis event ( DBE ) : `` A postulated event used in the design to establish the acceptable performance requirements of the structures , systems , and components . ''  design-basis explosion : `` An explosion that is the most severe design basis accident of that type applicable to the area under consideration . ''  design-basis fire : `` A fire that is the most severe design basis accident of this type . In postulating such a fire , failure of automatic and manual fire suppression provisions shall be assumed except for those safety class items or systems that are specifically designed to remain available ( structurally or functionally ) through the event . ''  design-basis flood : `` A flood that is the most severe design basis accident of that type applicable to the area under consideration . ''  design-basis tornado ( DBT ) : `` A tornado that is the most severe design basis accident of that type applicable to the area under consideration . ''   Circumstances like the 2011 Tōhoku earthquake and tsunami were not considered within the design basis of the plant , and so the resulting Fukushima I nuclear accidents were described using this terminology as `` beyond design basis accidents '' or `` non-design-basis accidents '' . However , some have claimed that the design basis for tsunami events at Fukushima was incorrect .   Accidents caused by poor design , failure to follow listed safety procedures , or other forms of human error are not considered to be beyond design basis accidents . The terminology can be unclear , however , because a poorly handled design basis accident can result in conditions beyond what was considered likely , causing a beyond design basis accident . For this reason , some industry experts have criticized the use of design basis terminology . The Three Mile Island accident and the Chernobyl disaster are examples of design basis accidents becoming non design basis accidents largely due to failures to follow the written operating procedures .

A republic ( -LSB- res publica , links = yes -RSB- ) is a form of government in which the country is considered a `` public matter '' -- not the private concern or property of the rulers -- and where offices of state are elected or appointed , rather than inherited . It is a government where the head of state is not a monarch .   In American English , the definition of a republic can also refer specifically to a government in which elected individuals represent the citizen body , known elsewhere as a representative democracy ( a democratic republic ) , and exercise power according to the rule of law ( a constitutional republic ) .   , 159 of the world 's 206 sovereign states use the word `` republic '' as part of their official names ; not all of these are republics in the sense of having elected governments , nor do all nations with elected governments use the word `` republic '' in their names .   Both modern and ancient republics vary widely in their ideology , composition , and practicality . In the classical and medieval period of Europe , many states were fashioned on the Roman Republic , which referred to the governance of the city of Rome , between it having kings and emperors . The Italian medieval and Renaissance political tradition , today referred to as `` civic humanism '' , is sometimes considered to derive directly from Roman republicans such as Sallust and Tacitus . However , Greek-influenced Roman authors , such as Polybius and Cicero , sometimes also used the term as a translation for the Greek politeia which could mean regime generally , but could also be applied to certain specific types of regime that did not exactly correspond to that of the Roman Republic . Republics were not equated with classical democracies such as Athens , but had a democratic aspect .   Republics became more common in the Western world starting in the late 18th century , eventually displacing absolute monarchy as the most common form of government in Europe . In modern republics , the executive is legitimized both by a constitution and by popular suffrage . In his work , `` The Spirit of the Laws '' , Montesquieu classified both democracies , where all the people have a share in rule , and aristocracies , where only some of the people rule , as republican forms of government .   Most often a republic is a single sovereign state , but there are also sub-sovereign state entities that are referred to as republics , or that have governments that are described as ` republican ' in nature . For instance , Article IV of the United States Constitution `` guarantee -LSB- s -RSB- to every State in this Union a Republican form of Government '' . In contrast , the Soviet Union was constitutionally described as a `` federal multinational state '' , composed of 15 republics , two of which -- Ukraine and Belarus -- had their own seats at the United Nations .

Range of motion ( or ROM ) , is the linear or angular distance that a moving object may normally travel while properly attached to another . It is also called range of travel ( or ROT ) , particularly when talking about mechanical devices and in mechanical engineering fields . For example , a sound volume control knob ( a rotary fader ) may have a 300 ° range of travel from the `` off '' or muted ( fully attenuated ) position at lower left , going clockwise to its maximum-loudness position at lower right .   As used in the biomedical and by weightlifters , range of motion refers to the distance and direction a joint can move between the flexed position and the extended position . The act of attempting to increase this distance through therapeutic exercises ( range of motion therapy -- stretching from flexion to extension for physiological gain ) is also sometimes called range of motion .

Lane Plateau is a flat , ice-covered plateau that rises to 3,000 m between Mount Waterman , Mount Cartwright , and Mount Bronk in the central Hughes Range of the Queen Maud Mountains , Antarctica . It trends north -- south for 9 nmi and is 2.5 nmi wide .   The plateau was discovered and photographed by R. Admiral Byrd on the Baselaying Flight of November 18 , 1929 , and surveyed by A.P. Crary , 1957 -- 58 . It was mapped by the United States Geological Survey from surveys , 1962 -- 63 , and U.S. Navy photography taken 1958 -- 63 . The plateau is named in honor of Neal Lane , Director of the National Science Foundation ( NSF ) from 1993 to 1998 . Under his leadership the NSF won congressional approval for rebuilding South Pole Station as a premier international science facility set to open at the beginning of the 21st century .

In mathematics , a rate is the ratio between two related quantities . If the denominator of the ratio is expressed as a single unit of one of these quantities , and if it is assumed that this quantity can be changed systematically ( i.e. , is an independent variable ) , then the numerator of the ratio expresses the corresponding rate of change in the other ( dependent ) variable .   The most common type of rate is `` per unit of time '' , such as speed , heart rate and flux . Ratios that have a non-time denominator include exchange rates , literacy rates and electric field ( in volts/meter ) .   In describing the units of a rate , the word `` per '' is used to separate the units of the two measurements used to calculate the rate ( for example a heart rate is expressed `` beats per minute '' ) . A rate defined using two numbers of the same units ( such as tax rates ) or counts ( such as literacy rate ) will result in a dimensionless quantity , which can be expressed as a percentage ( for example , the global literacy rate in 1998 was 80 % ) or fraction or as a multiple .   Often rate is a synonym of rhythm or frequency , a count per second ( i.e. , Hertz ) ; e.g. , radio frequencies or heart rate or sample rate .

Restricted airspace is an area ( volume ) of airspace typically used by the military in which the local controlling authorities have determined that air traffic must be restricted ( if not continually prohibited ) for safety or security concerns . It is one of many types of special use airspace designations and is depicted on aeronautical charts with the letter `` R '' followed by a serial number .   According to the United States Federal Aviation Administration ( FAA ) : `` Restricted areas denote the existence of unusual , often invisible , hazards to aircraft such as artillery firing , aerial gunnery , or guided missiles . Penetration of restricted areas without authorization from the using or controlling agency may be extremely hazardous to the aircraft and its occupants . ''   Restricted airspace zones may not be active ( `` hot '' ) at all times ; in such cases there are typically schedules of local dates and times available to aviators specifying when the zone is active , and at other times , the airspace is subject to normal VFR/IFR operation for the applicable airspace class . A few zones are activated by NOTAM ; an example is R-2503D over Camp Pendleton in southern California , between San Diego and Los Angeles . This particular zone , beginning at 2000ft above sea level over most of southern Camp Pendleton , can only be active for a certain number of days per year , thus allowing small planes to fly a direct route over land between the two metro areas instead of being diverted offshore or into mountainous terrain further inland .

The National Defense Authorization Act for Fiscal Year 1999 ( NDAA 1999 ) added Section 117 to United States Code Title 10 , which directed the Secretary of Defense to establish a `` comprehensive readiness reporting system '' that would `` measure in an objective , accurate , and timely manner '' the capability of the U.S. military to carry out the National Security Strategy , Defense Planning Guidance , and the National Military Strategy .   Additionally , the National Defense Authorization Act for Fiscal Year 2000 ( NDAA 2000 ) directed an independent study of the requirements for this comprehensive readiness reporting system , resulting in an Institute for Defense Analyses report titled `` Independent Review of DOD 's Readiness Reporting System '' released in November 2000 .   The overarching intent behind the Defense Readiness Reporting System ( DRRS ) is to help answer the question `` ready for what ? '' by providing both capability and resource data in an improved readiness reporting tool to broaden DoD-level readiness assessments .   DRRS represents a shift in how the Defense Department :   Thinks of readiness  Beyond narrow resource accounting  Synonymous with capability -- What can forces do ?

Komarr is a fictional planet in Lois McMaster Bujold 's Vorkosigan Saga series of novels and stories .   Discovered centuries prior to the Vorkosigan Saga , Komarr is undergoing a major terraforming project to make the outside air breathable . During this centuries-long program , the Komarrans are confined to domed cities , with controlled air supplies . The outside air is far too rich in carbon dioxide . The planet is also very cold , somewhat similar to Mars . At the time of the Vorkosigan saga , the most complicated life form outside the domes is a genetically modified peat moss . There is also a large orbital mirror , which increases amount of sunlight actually hitting the planet . The terraforming program , and the orbital mirror , are major plot points in the book Komarr .   Komarr has strategic importance because its local space contains the single known wormhole into Barrayar , the heart of the Barrayaran Empire . It is also a major trade nexus .   Capital City : Solstice .  Government : Komarr is ruled by the Barrayaran Empire , but has its own dominant class of oligarchs . The planet is divided into a number of equal-sized sectors , with responsibilities for regional government . Komarr is governed by the First Councilor , a position appointed by the Emperor that is equivalent in rank and responsibilities to the Viceroy of Sergyar . The plutocratic and nominal democracy is divided into two types of votes -- one person , one vote -- and `` extra votes '' that are granted to any settlers starting a new domed-city . These `` extra votes '' are inheritable and trade-able on a secondary market . The plutocratic oligarchies control the government by holding these extra votes . This system of extra votes becomes the basis of an attempted invasion by the Kibou-danii to wrest control of Komarr away from the Barrayarran Imperium .  Population : Many large domed metropolis-sized cities .  Economy : As Komarr controls at least six important wormhole routes ( to Barrayar , Sergyar , Escobar , Pol and Cetaganda , as well as a few other minor jump points ) , much commerce passes through the system and is taxed . Komarr 's economy is dominated by the oligarch families , whose large fleets are sent on trade runs ( lasting 5 -- 12 months ) to many areas throughout the galaxy , often returning with very large profits .


Question: As per data from NASA, the worldwide mean temperature for both terrestrial areas and oceans exceeded the twentieth-century baseline by approximately 0.9 degrees Celsius or roughly 1.62 degrees Fahrenheit. This indicates an ongoing trend in rising planetary warmth over recent decades.

20th Century Temperature Trends Confirmed by Recent Data
Recent data from NASA confirms that the globally averaged temperature across both land and ocean surfaces rose significantly throughout the twentieth century. Specifically, temperatures were found to be approximately 0.9 degrees Celsius (or 1.62 degrees Fahrenheit) higher compared to historical averages established within the last hundred years. This observation aligns closely with predictions stemming from numerous studies conducted under the auspices of the Intergovernmental Panel on Climate Change (IPCC).

The IPCC’s comprehensive assessment reports underscore how human activities—chiefly through increased atmospheric concentrations of greenhouse gases—are overwhelmingly responsible for recent climate shifts. Carbon dioxide, methane, and nitrous oxide emissions linked directly to industrial operations represent key contributors to escalating planetary warmth. Projections outlined by leading scientists suggest additional increases ranging from 0.3°C up to 4.8°C depending upon varying scenarios involving either minimal or maximal pollutant releases respectively.

These developments carry profound implications spanning diverse geographic locales. Expected outcomes encompass heightened air temperatures; accelerated sea level ascension; altered precipitation cycles; desertification intensifications particularly near equatorial latitudes; alongside intensified frequency/severity regarding certain meteorological phenomena e.g., heatwaves/drought conditions/heavy rains/snowfalls etcetera. Moreover, marine ecosystems face threats posed by ongoing oceanic acidification while terrestrial biomes confront risks tied to habitat alterations precipitated via thermal regime modifications. Consequences relevant specifically to Homo sapiens entail jeopardies impacting agricultural productivity owing to diminished grain outputs coupled potentially with evacuations necessitated following inundations triggered by surging coastal waters.

In light of these challenges, society grapples earnestly with devising appropriate countermeasures aimed at mitigating adverse consequences emanating from mounting GHG discharges whilst concurrently striving diligently towards enhancing adaptive capacities vis-a-vis anticipated perturbations. International frameworks such as those enshrined within treaties promulgated pursuant to conventions organized under United Nations auspices advocate robust curtailment strategies targeting substantial reductions in noxious effluent volumes discharged annually into ambient atmospheres. Meanwhile, public awareness concerning gravity inherent within prevailing circumstances appears gradually expanding albeit unevenly distributed geographically speaking wherein citizens residing within jurisdictions characterized hitherto by comparatively lower overall contributions towards cumulative stockpiles of airborne particulates remain relatively unconcerned despite bearing collective responsibility moving forward towards achieving shared objectives pertaining to safeguarding ecological integrity imperiled presently amidst unfolding crisis dynamics.

A debris disk is a circumstellar disk of dust and debris in orbit around a star . Sometimes these disks contain prominent rings , as seen in the image of Fomalhaut on the right . Debris disks have been found around both mature and young stars , as well as at least one debris disk in orbit around an evolved neutron star . Younger debris disks can constitute a phase in the formation of a planetary system following the protoplanetary disk phase , when terrestrial planets may finish growing . They can also be produced and maintained as the remnants of collisions between planetesimals , otherwise known as asteroids and comets .   By 2001 , over 900 candidate stars had been found to possess a debris disk . They are usually discovered by examining the star system in infrared light and looking for an excess of radiation beyond that emitted by the star . This excess is inferred to be radiation from the star that has been absorbed by the dust in the disk , then re-radiated away as infrared energy .   Debris disks are often described as massive analogs to the debris in the Solar System . Most known debris disks have radii of 10 -- 100 astronomical units ( AU ) ; they resemble the Kuiper belt in the Solar System , but with much more dust . Some debris disks contain a component of warmer dust located within 10 AU from the central star . This dust is sometimes called exozodiacal dust by analogy to zodiacal dust in the Solar System .

1719 Jens , provisional designation , is an asteroid from the middle region of the asteroid belt , approximately 19 kilometers in diameter . It was discovered on 17 February 1950 , by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany .   It orbits the Sun at a distance of 2.1 -- 3.2 AU once every 4 years and 4 months ( 1,581 days ) . Its orbit has an eccentricity of 0.22 and an inclination of 14 ° with respect to the ecliptic . First identified as at Simeiz Observatory in 1922 , Jens first used observation was taken at Turku in 1948 , extending the body 's observation arc by 2 years prior to its official discovery observation .   In 2010 , Jens was passing in front of the Tadpole Nebula ( see image obtained by WISE ) .   In September 2000 , American astronomer Brian D. Warner obtained two rotational light-curves , giving a rotation period of 5.867 and 5.87 hours with a brightness variation of 0.50 and 0.55 magnitude , respectively . In February 2006 , photometric observations by French amateur astronomer Laurent Bernasconi gave a concurring period of 5.873 hours with an amplitude of 0.55 magnitude . This well-defined period was further confirmed by a modeled light-curve using data from the Lowell Photometric Database , giving a period of 5.87016 hours .   It is classified as S - and C-type asteroid by the LCDB and Pan-STARRS , respectively . According to the surveys carried out by the Infrared Astronomical Satellite IRAS and NASA 's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission , Jens measures between 18.93 and 21.61 kilometers in diameter and its surface has an albedo between 0.085 and 0.149 . The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1048 and calculates a diameter of 18.76 kilometers based on an absolute magnitude of 11.7 .   This minor planet was named by the discoverer for his grandson . Karl Reinmuth also named the consecutively numbered asteroid , 1720 Niels , after one of his grandsons . Naming citation was published before November 1977 .

Laika ( Лайка -LSB- lajka -RSB- ) c. 1954 -- November 3 , 1957 ) was a Soviet space dog who became one of the first animals in space , and the first animal to orbit the Earth . Laika , a stray dog from the streets of Moscow , was selected to be the occupant of the Soviet spacecraft Sputnik 2 that was launched into outer space on November 3 , 1957 .   Little was known about the impact of spaceflight on living creatures at the time of Laika 's mission , and the technology to de-orbit had not yet been developed , so Laika 's survival was never expected . Some scientists believed humans would be unable to survive the launch or the conditions of outer space , so engineers viewed flights by animals as a necessary precursor to human missions . The experiment aimed to prove that a living passenger could survive being launched into orbit and endure a Micro-g environment , paving the way for human spaceflight and providing scientists with some of the first data on how living organisms react to spaceflight environments .   Laika died within hours from overheating , possibly caused by a failure of the central R-7 sustainer to separate from the payload . The true cause and time of her death were not made public until 2002 ; instead , it was widely reported that she died when her oxygen ran out on day six or , as the Soviet government initially claimed , she was euthanised prior to oxygen depletion .   On April 11 , 2008 , Russian officials unveiled a monument to Laika . A small monument in her honour was built near the military research facility in Moscow that prepared Laika 's flight to space . It features a dog standing on top of a rocket . She also appears on the Monument to the Conquerors of Space in Moscow .

Ranger 3 was a space exploration mission conducted by NASA to study the Moon . The Ranger 3 robotic spacecraft was launched January 26 , 1962 as part of the Ranger program . Due to a series of malfunctions , the spacecraft missed the Moon by 22,000 miles and entered a heliocentric orbit .   The Ranger 3 space probe was designed to transmit pictures of the lunar surface during a period of 10 minutes of flight prior to impacting on the Moon , to rough-land a seismometer capsule on the Moon , to collect gamma-ray data in flight , to study radar reflectivity of the lunar surface , and to continue testing of the Ranger program for development of lunar and interplanetary spacecraft .

( also written 2004 AS1 ) , also known by the temporary name AL00667 , is an Apollo-class near-Earth asteroid , first discovered on January 13 , 2004 , by the LINEAR project . Based on the asteroids brightness and assumed proximity to Earth , the asteroid was originally estimated to be only 30 meters in diameter .   Although rather ordinary , it caused some controversy in astronomical circles due to initial projections posted on the web by the Minor Planet Center ( MPC ) suggesting an imminent collision with Earth on or about January 15 with a likelihood of 1:4 . These projections came from very early observations , and turned out to be inaccurate ( which is an ordinary occurrence in astronomy , as new observations refine the projected path of an object ) . In fact , the poster at the MPC had not realised that the data he had posted was essentially an impact prediction .   The general media did not get hold of the story at the time .   The asteroid passed Earth on 16 February 2004 at a distance of 0.08539 AU ( or 33 times the distance from Earth to the Moon ) , posing no threat . It is an Apollo asteroid , with perihelion at 0.88 AU , a rather low eccentricity of 0.17 , an inclination of 17 ° and an orbital period of 1.11 years .   With an absolute magnitude ( H ) of 20.5 , the asteroid is now known to be around 210 - 470 m in diameter , depending on the albedo ( the amount of light it reflects ) .

A one-hundred-year flood is a flood event that has a 1 % probability of occurring in any given year . The 100-year flood is also referred to as the 1 % flood , since its annual exceedance probability is 1 % . For river systems , the 100-year flood is generally expressed as a flowrate . Based on the expected 100-year flood flow rate , the flood water level can be mapped as an area of inundation . The resulting floodplain map is referred to as the 100-year floodplain . Estimates of the 100-year flood flowrate and other streamflow statistics for any stream in the United States are available . In the UK The Environment Agency publishes a comprehensive map of all areas at risk of a 1 in 100 year flood ( Flood zone 3 ) Areas near the coast of an ocean or large lake also can be flooded by combinations of tide , storm surge , and waves . Maps of the riverine or coastal 100-year floodplain may figure importantly in building permits , environmental regulations , and flood insurance .

Kosmos 2209 ( Космос 2209 meaning Cosmos 2209 ) is a Russian US-KS missile early warning satellite which was launched in 1992 as part of the Russian Space Forces ' Oko programme . The satellite is designed to identify missile launches using optical telescopes and infrared sensors .   Kosmos 2209 was launched from Site 81/23 at Baikonur Cosmodrome in Kazakhstan . A Proton-K carrier rocket with a DM-2 upper stage was used to perform the launch , which took place at 18:01 UTC on 10 September 1992 . The launch successfully placed the satellite into geostationary orbit . It subsequently received its Kosmos designation , and the international designator 1992-059A . The United States Space Command assigned it the Satellite Catalog Number 22112 .   It was operational for about 4 years .

1 Lacertae ( 1 Lac ) is a solitary star in the northern constellation of Lacerta . It is visible to the naked eye with an apparent magnitude of 4.15 . Based upon measurements by the Hipparcos spacecraft , this star is located at a distance of roughly 420 light years . A stellar classification of K3II-III suggests this is an evolved giant star . It has expanded to an estimated 51 times the radius of the Sun . The effective temperature of 4,350 K for the stellar atmosphere gives it the orange-hued glow of a K-type star .
