Question: Numerous floral species throughout Britain currently exhibit blooming patterns that precede historical records by up to two-and-a-half centuries.

 Spring Blossoms Across Britain: An Early Arrival
Across the British Isles, spring has sprung much sooner than anticipated, marking the earliest blooming period observed within two-and-a-half centuries. Flowers ranging from delicate daffodils to vibrant violets are unfurling their petals weeks ahead of schedule—a phenomenon attributed largely to rising temperatures linked to climate change.
Cherry blossoms serve as poignant examples; these beautiful blooms typically grace parks and gardens during late March through April but were spotted flourishing far earlier this year. Their premature appearance aligns with broader trends affecting hundreds of floral species nationwide. From Cornwall’s coastlines to Scotland’s highlands, nature appears eager to embrace warmer weather—perhaps too eagerly given its long-term implications for ecosystems unprepared for accelerated seasonal shifts.
This early bloom underscores how profoundly climate alteration impacts flora schedules traditionally governed by predictable cycles tied to daylight hours and average air conditions. With each passing season, scientists note deviations growing increasingly pronounced—an unsettling trend likely exacerbated without significant intervention aimed at curbing greenhouse gases contributing to planetary overheating. Thus while Britons might initially welcome sightseeing among lush landscapes seemingly unaffected by winter chill, they should remain mindful of underlying ecological concerns necessitating urgent attention beyond mere aesthetic appreciation.

Deep & Meaningless is the second album by English folk singer-songwriter duo John Otway and Wild Willy Barrett . It was released in 1978 . The album included the song `` Beware Of The Flowers ( ` Cos I 'm Sure They 're Going To Get You Yeah ) '' , which was voted Britain 's seventh most popular song lyric in a 1999 BBC online poll . The song 's strong showing -- ahead of The Moody Blues ' `` Nights in White Satin '' and Hoagy Carmichael 's `` Stardust '' -- was the result of what Otway 's website described as a `` well orchestrated campaign '' by fans .   Allmusic rates the album as a `` triumph '' and gives it 4 1/2 out of 5 stars .

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 .

J. R. W. ( Ralph ) Hollins ( born 1931 ) is a naturalist , born at Martin in the English county of Hampshire .   Hollins became active in Hampshire Wildlife Trust and Hampshire Ornithological Society during the 1980s , serving on committees of both organisations .   He is best known as the co-discoverer ( with K. Turner ) of Red Helleborine at Hawkley Warren , near Petersfield , in 1986 , one of only three British sites where this species remained extant at the end of the 20th century .   He is also responsible for setting up and running the website Nature Notes for the Havant area , originally launched in 1997 and still current in 2010 .

Landed gentry is a largely historical British social class consisting of land owners who could live entirely from rental income . It was distinct from , and socially `` below '' , the aristocracy or peerage , although in fact some of the landed gentry were as wealthy as some peers . They often worked as administrators of their own lands , while others became public , political and armed forces figures . The decline of this privileged class largely stemmed from the 1870s agricultural depression .   The designation `` landed gentry '' originally referred exclusively to members of the upper class who were landlords and also commoners in the British sense , that is , they did not hold peerages , but usage became more fluid over time . Similar or analogous social systems of landed gentry also sprang up in countries that maintained a colonial system ; the term is employed in many British colonies such as the Colony of Virginia and some parts of India . By the late 19th century , the term was also applied to peers such as the Duke of Westminster who lived on landed estates . The book series Burke 's Landed Gentry recorded the members of this class . Successful burghers often used their accumulated wealth to buy country estates , with the aim of establishing themselves as landed gentry .

Dierama pendulum , commonly known as fairy bell , hair bell and wedding bell , is a species of Iridaceae endemic to the Eastern Cape and first collected in 1772 by the Swedish naturalist Carl Peter Thunberg near Essenbos on the Kromme River or Kromrivier which flows down the Langkloof . In 1845 the genus Dierama was established by Karl Koch ( 1809-1879 ) based on this specimen . Before that the plant had been placed in various genera including Ixia , Sparaxis and Watsonia . The species name has been misapplied to D. inyangense , D. densiflorum and to D. plowesii .   ` Dierama ' is Greek for ` funnel ' and describes the flower 's shape , while ` pendulum ' is the Latin word for hanging suspended . The plant is some 2 metres tall with extremely slender and wiry stems , dividing into hair-like branches , gracefully curving under the weight of the flowers , and readily nodding in the lightest of breezes . As do all in the genus , it has a large flattened corm covered in layers of tunics made up of dry fibres . A new corm is formed every growing season , the old defunct corms remaining intact for many years , stacked one above the other . It grows in dense and fairly extensive tufts from Knysna to the Amatolas in the Eastern Cape and , when not in flower , the tall , slender , rigid leaves resemble those of a coarse sedge . The flower colour ranges from pink to pure white , while the tough , rounded capsule contains numerous angular brown seeds .   The ( Southern ) Sotho people of the Kingdom of Lesotho use a decoction of the corm of Dierama pendulum as an enema with strongly purgative properties .

Rhododendron arboreum , the tree rhododendron , also known as burans or gurans , is an evergreen shrub or small tree with a showy display of bright red flowers . It is found in Bhutan , China , India , Myanmar , Nepal , Sri Lanka , Pakistan and Thailand . Rhododendron arboreum is the national flower of Nepal ; in India it is the state tree of Uttarakhand and state flower of Himachal Pradesh and Nagaland .

As a means of recording the passage of time , the 14th century was the century lasting from January 1 , 1301 , to December 31 , 1400 . Political and natural disasters ravaged Europe , as well as the four khanates of the Mongol Empire . Consequently , the Mongol court was driven out of China and retreated to Mongolia , the Ilkhanate collapsed in Persia , the Chaghatayid dissolved into two parts , and the Golden Horde lost its position as great power in Eastern Europe .   In Europe , the Black Death claimed between 75 and 200 million lives , while England and France fought in the protracted Hundred Years ' War after the death of Charles IV , King of France led to a claim to the French throne by Edward III , King of England . This period is considered the height of chivalry and marks the beginning of strong separate identities for both England and France .

`` L'horloge fleurie '' ( or `` flower clock '' ) was - with its diameter of 5 metres - the largest of its kind in the world until the installation of a 15 metres flower clock in Tehran , Iran on 7 June 2005 .   Geneva 's `` L'horloge fleurie '' was created in 1955 as a symbol of the city 's watchmakers and dedication to nature . Its second hand is the longest in the world at 2.50 meters . It is situated at the western edge of the Jardin Anglais . Usually , around 6500 flowers and shrubs are used as decoration for this clock . The decoration is changed each time the seasons of the year change .


Question:
 Carbon dioxide concentrations in our atmosphere have escalated swiftly, attaining heights unseen since prehistoric times dating back several million years ago. This unprecedented surge mirrors an alarming departure from historical norms, underscoring pressing concerns over climate change impacts.
(Note: I aimed at maintaining syntactical structure while changing some terms and adding more detail to keep it complex.)

 Rapid Increase in Atmospheric CO2 Levels: A Historical Perspective
The concentration of carbon dioxide (CO2) within Earth’s atmosphere represents only around 0.04%—or roughly 415 parts per million (ppm)—yet holds significant influence over planetary temperatures via enhanced greenhouse effects. Throughout history, CO2 levels have fluctuated widely; they've soared upwards of 7,000 ppm during the Cambrian era some half-billion years back but plummeted down near 180 ppm amid glacial periods spanning recent millennia.
Intrinsically tied to nature's intricate carbon cycle—a dynamic interchange involving seas, terrestrial ecosystems, lithosphere, and living beings—this molecule serves crucial roles across diverse lifeforms. Photosynthetic organisms harness sunlight converting ambient CO2 alongside H2O into organic matter essential for sustenance throughout food webs.
However, contemporary concerns revolve around escalating CO2 discharges linked predominantly to anthropocentric pursuits, notably combustion-driven industries and forest clearance. Since pre-industrial times circa late-eighteenth-century when baseline readings hovered around 280 ppm, humanity has triggered a surge exceeding forty percent, propelling us beyond historical norms established over ten thousand years. By early twenty-first century benchmarks, we surpassed critical thresholds approaching four hundred ppm—an apex unseen possibly even before dinosaurs roamed sixty-six million years earlier!
This alarming trajectory continues unabated, clocking gains averaging nearly double digits annually while intensifying pace. Recent milestones highlight grim realities: surpassing four hundred ppm barrier in May 2013 followed swiftly by consecutive breaches reflecting unyielding momentum. Approximately three-quarters of emitted pollutants get absorbed naturally either by terrestrial sinks or marine reservoirs exacerbating acidity challenges faced globally.

The 11th millennium BCE in North American history provides a timeline of events occurring within the North American continent from 11000 BCE through 10001 BCE in the Gregorian calendar . 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 record 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 also may yield a general bias in the dating in this timeline .   12,340 BCE -- 10,800 BCE : a stone-lined hearth and coprolites left in Paisley Caves , Oregon  10,675 ± 95 BCE : Buhl woman , one of the oldest known humans in North America , was buried near present-day Buhl , Idaho with a pressure-flaked , pointed obsidian tool  10,200 BCE : Cooper Bison skull is painted with a red zigzag in present-day Oklahoma , becoming the oldest known painted object in North America .

Landscape history is the study of the way in which humanity has changed the physical appearance of the environment - both present and past . It is sometimes referred to as landscape archaeology . It was first recognised as a separate area of study during the 20th century and uses evidence and approaches from other disciplines including archaeology , architecture , ecology , aerial photography , local history and historical geography .

The ( n-p ) reaction is an example of a nuclear reaction . It is the reaction which occurs when a neutron enters a nucleus and a proton leaves the nucleus simultaneously .   For example , sulfur-32 ( S-32 ) undergoes an ( n , p ) nuclear reaction when bombarded with neutrons , thus forming phosphorus-32 ( P-32 ) .   The nuclide nitrogen-14 ( N-14 ) can also undergo an ( n , p ) nuclear reaction to produce carbon-14 ( C-14 ) . This nuclear reaction 14N ( n , p ) 14C continually happens in the earth 's atmosphere , forming equilibrium amounts of the radionuclide carbon-14 .   Most ( n , p ) reactions have threshold neutron energies below which the reaction can not take place as a result of the charged particle in the exit channel requiring energy ( usually more than a MeV ) to overcome the Coulomb barrier experienced by the emitted proton . The ( n , p ) nuclear reaction 14N ( n , p ) 14C is an exception to this rule , and is exothermic - it can take place at all incident neutron energies . The 14N ( n , p ) 14C nuclear reaction is responsible for most of the radiation dose delivered to the human body by thermal neutrons -- these thermal neutrons are absorbed by the nitrogen ( N-14 ) in proteins , causing a proton to be emitted ; the emitted proton deposits its kinetic energy over a very short distance in the body tissue , thereby depositing radiation dose .

In stereochemistry , the Klyne -- Prelog system ( named for William Klyne and Vladimir Prelog ) for describing conformations about a single bond offers a more systematic means to unambiguously name complex structures , where the torsional or dihedral angles are not found to occur in 60 ° increments . Klyne notation views the placement of the substituent on the front atom as being in regions of space called anti/syn and clinal/periplanar relative to a reference group on the rear atom . A plus or minus sign is placed at the front to indicate the sign of the dihedral angle . Anti or syn indicates the substituents are on opposite sides or the same side , respectively . Clinal substituents are found within 30 ° of either side of a dihedral angle of 60 ° ( from 30 ° to 90 ° ) , 120 ° ( 90 ° -- 150 ° ) , 240 ° ( 210 ° -- 270 ° ) , or 300 ° ( 270 ° -- 330 ° ) . Periplanar substituents are found within 30 ° of either 0 ° ( 330 ° -- 30 ° ) or 180 ° ( 150 ° -- 210 ° ) . Juxtaposing the designations produces the following terms for the conformers of butane ( see Alkane stereochemistry for an explanation of conformation nomenclature ) : gauche butane is syn-clinal ( + sc or -- sc , depending on the enantiomer ) , anti butane is anti-periplanar , and eclipsed butane is syn-periplanar .

( also written 2006 SU49 ) is a near-Earth asteroid that had a 1 in 42,000 chance of impacting Earth on January 22 , 2029 . By October 29 , 2006 , it was listed with a Torino Scale impact risk value of 0 . It was removed from the Sentry Risk Table on November 23 , 2006 . It is now known that on January 28 , 2029 , the asteroid will be 0.00818 AU from Earth .   It is a near-Earth asteroid that received minor attention in late September and early October 2006 because initial observations indicated a higher than usual probability that it would strike the Earth in 2029 . However , the Near-Earth Object ( NEO ) Office at NASA 's Jet Propulsion Laboratory ( JPL ) removed from its risk list as additional observations provided improved predictions that eliminated the possibility of an impact on Earth or the Moon through 2106 . Similarly , NEODyS estimates show a zero impact probability through 2080 .   briefly led the Earth-impact hazard list from September 27 , 2006 , through October 4 , 2006 , temporarily displacing ( 144898 ) 2004 VD17 from the number one position . At the time , both held a Torino scale of level 1 and were the only asteroids to hold a Torino value greater than 0 .   Even though has an Earth MOID of 0.0003 AU , the orbit and future close approaches are well determined with an orbital uncertainty of 0 .   was discovered on September 20 , 2006 , by the Spacewatch project at the University of Arizona . The object is estimated at 380 meters in diameter with a mass of about 7.3 kg .

Late modern period , the late part of the modern history , may ambiguously refer to :  History  In conservative historiography , a specific transformational period of modern history following the 17th century ( Great Divergence )  The period of modernity from 1900 to present in the historical periodization scheme of philosopher Marshall Berman   Philosophy and art  Late modernism , a period in art history ( post-World War II to present )  Late , liquid , or high modernity , defined by certain sociologists as the most recent phase of modernity ( late 20th century to present )

A rete mirabile ( Latin for `` wonderful net '' ; plural retia mirabilia ) is a complex of arteries and veins lying very close to each other , found in some vertebrates , mainly warm-blooded ones . The rete mirabile utilizes countercurrent blood flow within the net ( blood flowing in opposite directions ) to act as a countercurrent exchanger . It exchanges heat , ions , or gases between vessel walls so that the two bloodstreams within the rete maintain a gradient with respect to temperature , or concentration of gases or solutes . This term was coined by Galen .

Latent hypoxia occurs when a diver under pressure has a tissue oxygen concentration that is sufficient to support consciousness at that pressure , but insufficient at surface pressure . This problem is associated with freediving blackout and the presence of hypoxic breathing gas mixtures in underwater breathing apparatus , particularly in diving rebreathers .   The term latent hypoxia strictly refers to the situation while the potential victim is still conscious , but is also loosely applied to the consequential blackout , which is a form of hypoxic blackout also referred to as blackout of ascent or deep water blackout , though deep water blackout is also used to refer to the final stage of nitrogen narcosis .

 Rapid Increase in Atmospheric CO2 Levels: An Unprecedented Climatic Challenge
The concentration of carbon dioxide (CO2), a critical component of Earth’s atmosphere, has escalated dramatically in recent decades, surpassing levels unseen for millions of years. This potent greenhouse gas plays a pivotal role in regulating planetary temperatures but now contributes significantly to global warming. Historically, CO2 was maintained within narrow bounds through intricate biological cycles involving plants, oceans, and volcanic activity. However, modern industrial practices, particularly burning fossil fuels—coal, oil, and natural gas—and extensive deforestation, have disrupted this balance.
Natural environments once absorbed substantial amounts of CO2; forests acted as vital sinks while seas neutralized acidity resulting from dissolved gases. Yet, contemporary pressures have overwhelmed nature’s capacity to mitigate excesses. Consequently, atmospheric CO2 has soared past historical norms, triggering profound changes across ecosystems globally. These alterations manifest visibly through glacial retreat, sea-level rise, altered precipitation patterns, and intensified weather events—all hallmarks of escalating average temperatures attributed directly to heightened greenhouse effect intensity.
Moreover, rising CO2 impacts marine realms profoundly, instigating ocean acidification—a phenomenon detrimental to shell-forming organisms essential for maintaining complex food webs underpinning aquatic life diversity. Simultaneously, terrestrial flora experiences both positive effects (enhanced plant growth) alongside negative repercussions (increased vulnerability to pests/diseases). Thus, understanding how elevated CO2 influences various biomes becomes crucial for predicting future ecological trajectories accurately.
Addressing this urgent crisis necessitates concerted international action aimed at curbing emissions drastically whilst investing heavily into renewable alternatives capable of powering societies sustainably without exacerbating existing conditions. Additionally, reforestation initiatives coupled with innovative technologies designed specifically for capturing/storing CO2 represent promising strategies toward mitigating ongoing damage inflicted upon Earth’s delicate biosphere. Ultimately, recognizing humanity’s pivotal role in precipitating current trends underscores imperative need for immediate intervention if we hope to preserve habitable environment conducive supporting diverse forms existence moving forward.

Radiation protection , sometimes known as radiological protection , is defined by the International Atomic Energy Agency ( IAEA ) as `` The protection of people from harmful effects of exposure to ionizing radiation , and the means for achieving this '' . The IAEA also states `` The accepted understanding of the term radiation protection is restricted to protection of people . Suggestions to extend the definition to include the protection of non-human species or the protection of the environment are controversial '' .   Ionizing radiation is widely used in industry and medicine , and can present a significant health hazard . It causes microscopic damage to living tissue , which can result in skin burns and radiation sickness at high exposures ( known as `` tissue '' or `` deterministic '' effects ) , and statistically elevated risks of cancer at low exposures ( `` stochastic effects '' ) .   Fundamental to radiation protection is the reduction of expected dose and the measurement of human dose uptake . For radiation protection and dosimetry assessment the International Committee on Radiation Protection ( ICRP ) and International Commission on Radiation Units and Measurements ( ICRU ) have published recommendations and data which is used to calculate the biological effects on the human body , and set regulatory and guidance limits .

The Late Heavy Bombardment ( abbreviated LHB and also known as the lunar cataclysm ) is an event thought to have occurred approximately 4.1 to 3.8 billion years ( Ga ) ago , at a time corresponding to the Neohadean and Eoarchean eras on Earth . During this interval , a disproportionately large number of asteroids are theorized to have collided with the early terrestrial planets in the inner Solar System , including Mercury , Venus , Earth , and Mars . The LHB happened after the Earth and other rocky planets had formed and accreted most of their mass , but still quite early in Earth 's history .   Evidence for the LHB derives from lunar samples brought back by the Apollo astronauts . Isotopic dating of Moon rocks implies that most impact melts occurred in a rather narrow interval of time . Several hypotheses attempt to explain the apparent spike in the flux of impactors ( i.e. asteroids and comets ) in the inner Solar System , but no consensus yet exists . The Nice model , popular among planetary scientists , postulates that the giant planets underwent orbital migration and in doing so , scattered objects in the asteroid and/or Kuiper belts into eccentric orbits , and into the path of the terrestrial planets . Other researchers argue that the lunar sample data do not require a cataclysmic cratering event near 3.9 Ga , and that the apparent clustering of impact-melt ages near this time is an artifact of sampling materials retrieved from a single large impact basin . They also note that the rate of impact cratering could differ significantly between the outer and inner zones of the Solar System .

Daylight is the combination of all direct and indirect sunlight outdoors during the daytime , which includes :  Sunlight , the total spectrum of the electromagnetic radiation given off by the Sun  Diffuse sky radiation , solar radiation reaching the Earth 's surface after having been scattered by molecules or suspensoids in the atmosphere   Daylight may also refer to :

The Dark Ages Radio Explorer ( DARE ) mission is a proposed concept lunar orbiter intended to identify redshifted emanations from primeval hydrogen atoms just as the first stars began to emit light . DARE will use the precisely redshifted 21-cm transition line from neutral hydrogen ( 1420.00 MHz emissions ) to view and pinpoint the formation of the first illuminations of the universe .   Also , this is the period ending the Dark Ages of the universe . The orbiter will explore the universe as it was from around 80 million years to 420 million years after the Big Bang . The mission will deliver data pertaining to the formation of the first stars , the initial black hole accretions , and the reionization of the universe . Computer models of galaxy formation will also be tested .   This mission might also add to research on dark matter decay . The DARE program will also provide insight for developing and deploying lunar surface telescopes that add to refined exoplanet exploration of nearby stars . It is expected to launch in either 2021 or 2022 .

A landscape is the visible features of an area of land , its landforms and how they integrate with natural or man-made features .    A landscape includes the physical elements of geophysically defined landforms such as ( ice-capped ) mountains , hills , water bodies such as rivers , lakes , ponds and the sea , living elements of land cover including indigenous vegetation , human elements including different forms of land use , buildings and structures , and transitory elements such as lighting and weather conditions .   Combining both their physical origins and the cultural overlay of human presence , often created over millennia , landscapes reflect a living synthesis of people and place that is vital to local and national identity . The character of a landscape helps define the self-image of the people who inhabit it and a sense of place that differentiates one region from other regions . It is the dynamic backdrop to people 's lives . Landscape can be as varied as farmland , a landscape park , or wilderness .   The earth has a vast range of landscapes , including the icy landscapes of polar regions , mountainous landscapes , vast arid desert landscapes , islands and coastal landscapes , densely forested or wooded landscapes including past boreal forests and tropical rainforests , and agricultural landscapes of temperate and tropical regions .   The activity of modifying the visible features of an area of land is referred to as landscaping .

Rice is the seed of the grass species Oryza sativa ( Asian rice ) or Oryza glaberrima ( African rice ) . As a cereal grain , it is the most widely consumed staple food for a large part of the world 's human population , especially in Asia . It is the agricultural commodity with the third-highest worldwide production ( rice , 741.5 million tonnes in 2014 ) , after sugarcane ( 1.9 billion tonnes ) and maize ( 1.0 billion tonnes ) .   Since sizable portions of sugarcane and maize crops are used for purposes other than human consumption , rice is the most important grain with regard to human nutrition and caloric intake , providing more than one-fifth of the calories consumed worldwide by humans . There are many varieties of rice and culinary preferences tend to vary regionally .   Rice , a monocot , is normally grown as an annual plant , although in tropical areas it can survive as a perennial and can produce a ratoon crop for up to 30 years . Rice cultivation is well-suited to countries and regions with low labor costs and high rainfall , as it is labor-intensive to cultivate and requires ample water . However , rice can be grown practically anywhere , even on a steep hill or mountain area with the use of water-controlling terrace systems . Although its parent species are native to Asia and certain parts of Africa , centuries of trade and exportation have made it commonplace in many cultures worldwide .   The traditional method for cultivating rice is flooding the fields while , or after , setting the young seedlings . This simple method requires sound planning and servicing of the water damming and channeling , but reduces the growth of less robust weed and pest plants that have no submerged growth state , and deters vermin . While flooding is not mandatory for the cultivation of rice , all other methods of irrigation require higher effort in weed and pest control during growth periods and a different approach for fertilizing the soil .   The name wild rice is usually used for species of the genera Zizania and Porteresia , both wild and domesticated , although the term may also be used for primitive or uncultivated varieties of Oryza .

Deglaciation describes the transition from full glacial conditions during ice ages , to warm interglacials , characterized by global warming and sea level rise due to change in continental ice volume ( IPCC AR5 ) . Thus , it refers to the retreat of a glacier , an ice sheet or frozen surface layer , and the resulting exposure of the Earth 's surface . The decline of the cryosphere due to ablation can occur on any scale from global to localized to a particular glacier . After the Last Glacial Maximum ( ca. 21k years ago ) , the last deglaciation begun , which lasted until the early Holocene .   The previous deglaciation took place between approximately 22ka until 11.5 ka . This occurred when there was an annual mean atmospheric temperature on the earth that increased by roughly 5 ° C , which was also accompanied by regional high-latitude warming that exceeded 10 ° C . This was also followed by noteworthy deep-sea and tropical-se warming , between about 1-2 ° C ( deep-sea ) and 2-4 ° C ( tropical sea ) . Not only did this warming occur , but the global hydrological budget also experienced noticeable changes and regional precipitation patters changed . As a result of all of this , the worlds main ice sheets , including the ones located in Eurasia , North America and parts of the Antarctic Ice Sheets melted . As a consequence , sea levels rose roughly 120 metres ) . These processes did not occur steadily , and they also did not occur at the same time .

100 or one hundred ( Roman numeral : ) is the natural number following 99 and preceding 101 .   In medieval contexts , it may be described as the short hundred or five score in order to differentiate the English and Germanic use of `` hundred '' to describe the long hundred of six score or 120 .

Diathermancy ( from `` dia '' through and `` thermē '' heat ) is the property of some fluids that allows rays of light through them without itself being heated . A diathermanous fluid is thus `` permeable '' by heat . ) . Diathermany was first described by German physicist and chemist Heinrich Magnus in the 1800s . Atmospheric air is diathermanous ; therefore , air is not heated by sunshine , but by long wave heat reflected by soil , and especially , water on the Earth surface . Water , on the contrary , is not diathermanous , and it is heated by sunshine directly .

 Rapid Increase in Atmospheric CO2 Levels: A Historical Perspective
Atmospheric concentrations of carbon dioxide (CO2), a critical greenhouse gas responsible for regulating Earth’s temperature, have been rising dramatically since the Industrial Revolution. Today, we're witnessing CO2 levels surpass those recorded during any period within the past few million years—a stark reality attributed largely to increased burning of fossil fuels and deforestation. These elevated CO2 amounts contribute significantly to enhanced greenhouse effects, leading to global warming trends observed across various ecosystems. Understanding historical fluctuations helps contextualize current changes; however, recent spikes far exceed typical variations documented through paleoclimatology studies. Scientists utilize ice cores, tree rings, sediment layers, and coral reefs to reconstruct ancient atmospheric compositions—evidences pointing unequivocally towards anthropogenic influences dominating modern-day scenarios. Addressing this imbalance requires urgent action aimed at curbing emissions while promoting sustainable practices conducive to preserving ecological stability.

Laughter is a physical reaction in humans and some other species of primate , consisting typically of rhythmical , often audible contractions of the diaphragm and other parts of the respiratory system . It is a response to certain external or internal stimuli . Laughter can arise from such activities as being tickled , or from humorous stories or thoughts . Most commonly , it is considered a visual expression of a number of positive emotional states , such as joy , mirth , happiness , relief , etc. . On some occasions , however , it may be caused by contrary emotional states such as embarrassment , apology , or confusion such as nervous laughter or courtesy laugh . Age , gender , education , language , and culture are all factors as to whether a person will experience laughter in a given situation .   Laughter is a part of human behavior regulated by the brain , helping humans clarify their intentions in social interaction and providing an emotional context to conversations . Laughter is used as a signal for being part of a group -- it signals acceptance and positive interactions with others . Laughter is sometimes seen as contagious , and the laughter of one person can itself provoke laughter from others as a positive feedback . This may account in part for the popularity of laugh tracks in situation comedy television shows .   The study of humor and laughter , and its psychological and physiological effects on the human body , is called gelotology .

In cooking , reduction is the process of thickening and intensifying the flavor of a liquid mixture such as a soup , sauce , wine , or juice by simmering or boiling .   Reduction is performed by simmering or boiling a liquid such as stock , fruit or vegetable juices , wine , vinegar , or a sauce until the desired volume is reached by evaporation . This is done without a lid , enabling the vapor to escape from the mixture . Different components of the liquid will evaporate at slightly different temperatures , and the goal of reduction is to drive away those with lowest points of evaporation . It thus can be seen as a form of distillation , capturing those components that have the highest boiling point .   While reduction does concentrate the flavors left in the pan , reducing too much will drive away all liquid in the sauce , leaving a `` sticky , burnt coating '' on the pan .

12 ( twelve -LSB- ˈtwɛlv -RSB- ) is the natural number following 11 and preceding 13 . The product of the first three factorials , twelve is a superior highly composite number , divisible by 2 , 3 , 4 , and 6 . It is central to many systems of counting , including the Western calendar and units of time , and frequently appears in the Abrahamic religions .

Patients are exposed to ionizing radiations when they undergo diagnostic examinations using x-rays or radiopharmaceuticals , therapy of cancer or benign lesions using radiations emitted by radioisotopes or those by radiation generators ; and in interventional procedures using fluoroscopy . There has been a tremendous increase in the use of ionizing radiation in medicine during recent decades . Health professionals and patients are concerned about the harmful effects of radiation . International Atomic Energy Agency ( IAEA ) has established a programme on radiological protection of patients in recognition of the increasing importance of this topic . The emphasis in the past had been on radiation protection of staff and this emphasis has helped to reduce radiation doses to staff to levels much below the dose limits prescribed by the International Commission on Radiological Protection ( ICRP ) and accepted by most countries . The recent emphasis on radiation protection of patients is helping in developing strategies to reduce radiation doses to patient without compromising on diagnostic or therapeutic purpose .

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 . ''

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 .


Question: The term "deterioration" pertains specifically to a reduction in growth rates of trees located in higher latitudes, rather than an overall decrease in worldwide temperatures; this topic has been transparently addressed within scientific publications as well as Intergovernmental Panel on Climate Change (IPCC) assessments.

 Contextualizing Tree-Ring Data in Climate Studies
The term "decline" often mentioned within academic literature and Intergovernmental Panel on Climate Change (IPCC) reports specifically pertains to variations observed in Northern Hemisphere tree-ring widths since around 1960; it doesn't indicate any decrease in global temperatures but rather highlights discrepancies in certain proxy records. These discussions are transparently addressed across numerous peer-reviewed studies and official assessments. Proxy indicators, such as tree rings, serve crucial roles in reconstructing past climates when instrumental measurements weren’t available. However, researchers acknowledge limitations regarding how well some proxies capture recent warmth accurately—this challenge is part of ongoing dialogue among experts aiming to refine historical climate reconstructions.
In light of controversies sparked during events akin to the late-2009 unauthorized release of emails involving climate scientists—a breach originating from England’s prestigious institution—the integrity behind conclusions supporting anthropogenic global warming remains firm post-thorough inquiries debunking accusations levied against professionals engaged in studying Earth’s changing environment. Multiple independent panels comprising distinguished academics concluded there was neither fraudulent behavior nor unethical practices employed by those accused; instead emphasizing need for enhanced transparency concerning methodologies utilized & sharing datasets upon requests lodged by interested parties wishing scrutinize findings independently without compromising intellectual property rights held collectively amongst contributors involved collaboratively advancing understanding surrounding complex issues revolving around planetary health concerns exacerbated largely via human activities contributing significantly towards escalating atmospheric concentrations greenhouse gases triggering observable alterations manifesting themselves globally throughout terrestrial ecosystems spanning oceans skies alike thus necessitating urgent action aimed mitigating adverse impacts projected future scenarios outlined extensively latest assessment report compiled jointly international community members representing diverse disciplines united common goal safeguarding biosphere inhabitants generations yet unborn inherit habitable world capable sustaining life forms dependent upon delicate balance maintained countless millennia preceding dawn Industrial Revolution ushered era unparalleled technological advancement accompanied unforeseen consequences now requiring concerted effort reverse course set centuries ago embarking path irreversible damage inflicted unwittingly pursuit progress deemed necessary achieve modernity standards living enjoyed privileged few expense many others less fortunate bearing brunt negative externalities produced heedless exploitation finite resources endowed providence mankind stewardship entrusted preserving creation bestowed dominion exercising wisdom ensuring survival species threatened looming specter ecological collapse looms large horizon unless drastic measures taken immediately curb excesses unleashed unbridled capitalism run amok unchecked greed fueled insatiable desire wealth accumulation regardless cost borne collective conscience humanity hanging perilously precipice abyss staring back us daring plunge depths despair awaiting those fail recognize urgency hour act accordingly save ourselves destroying only home we've ever known.

In statistics , latent variables ( from Latin : present participle of lateo ( `` lie hidden '' ) , as opposed to observable variables ) , are variables that are not directly observed but are rather inferred ( through a mathematical model ) from other variables that are observed ( directly measured ) . Mathematical models that aim to explain observed variables in terms of latent variables are called latent variable models . Latent variable models are used in many disciplines , including psychology , economics , engineering , medicine , physics , machine learning/artificial intelligence , bioinformatics , natural language processing , econometrics , management and the social sciences .   Sometimes latent variables correspond to aspects of physical reality , which could in principle be measured , but may not be for practical reasons . In this situation , the term hidden variables is commonly used ( reflecting the fact that the variables are `` really there '' , but hidden ) . Other times , latent variables correspond to abstract concepts , like categories , behavioral or mental states , or data structures . The terms hypothetical variables or hypothetical constructs may be used in these situations .   One advantage of using latent variables is that it reduces the dimensionality of data . A large number of observable variables can be aggregated in a model to represent an underlying concept , making it easier to understand the data . In this sense , they serve a function similar to that of scientific theories . At the same time , latent variables link observable ( `` sub-symbolic '' ) data in the real world to symbolic data in the modeled world .   Latent variables , as created by factor analytic methods , generally represent `` shared '' variance , or the degree to which variables `` move '' together . Variables that have no correlation can not result in a latent construct based on the common factor model .

Land consumption as part of human resource consumption is the conversion of land with healthy soil and intact habitats into areas for industrial agriculture , traffic ( road building ) and especially urban human settlements . More formally , the EEA has identifid 3 land consuming activities :  The expansion of built-up area which can be directly measured ;  the absolute extent of land that is subject to exploitation by agriculture , forestry or other economic activities ; and  the over-intensive exploitation of land that is used for agriculture and forestry .  In all of those respects , land consumption is equivalent to typical land use in industrialized regions and civilizations .   Since often aforementioned conversion activities are virtually irreversible , the term land loss is also used . From 1990 to 2000 , 1.4 e6ha of open space were consumed in the U.S. . In Germany , land is being consumed at a rate of more than 70 ha every day ( ~ 250 e3ha per 10 years ) .   Land loss can also happen due to natural factors , like erosion or desertification - nevertheless most of those can also eventually be tracked back to human activities . Another slightly different interpretation of the term is the forced displacement or compulsory acquisition of a native people or settlers from their original land due to land grabbing , etc. . Again , in most cases , this will be due to economic reasons like search for profitable investment and commodification of natural resources .   Even though global land loss progresses at an alarming rate , the land footprint , the area required by some Western countries can a lot larger than the land actually used or even available in the country itself .   While land prices have surged in the first few years of the 21st century , land consumption economy still lacks environmental full-cost accounting to add the long-term costs of environmental degradation .

Reification ( also known as concretism , hypostatization , or the fallacy of misplaced concreteness ) is a fallacy of ambiguity , when an abstraction ( abstract belief or hypothetical construct ) is treated as if it were a concrete real event or physical entity .  In other words , it is the error of treating something that is not concrete , such as an idea , as a concrete thing . A common case of reification is the confusion of a model with reality : `` the map is not the territory '' .   Reification is part of normal usage of natural language ( just like metonymy for instance ) , as well as of literature , where a reified abstraction is intended as a figure of speech , and actually understood as such . But the use of reification in logical reasoning or rhetoric is misleading and usually regarded as a fallacy .

Kwashiorkor is a form of severe protein -- energy malnutrition characterized by edema , irritability , ulcerating dermatoses , and an enlarged liver with fatty infiltrates . Sufficient calorie intake , but with insufficient protein consumption , distinguishes it from marasmus . Kwashiorkor cases occur in areas of famine or poor food supply . Cases in the developed world are rare .   Jamaican pediatrician Cicely Williams introduced the name into the medical community in a 1935 Lancet article , two years after she published the disease 's first formal description in the Western medical literature . The name is derived from the Ga language of coastal Ghana , translated as `` the sickness the baby gets when the new baby comes '' or `` the disease of the deposed child '' , and reflecting the development of the condition in an older child who has been weaned from the breast when a younger sibling comes . Breast milk contains proteins and amino acids vital to a child 's growth . In at-risk populations , kwashiorkor may develop after a mother weans her child from breast milk , replacing it with a diet high in carbohydrates , especially sugar .

Resprouters are plant species that are able to survive fire by the activation of dormant vegetative buds to produce regrowth .   Plants may resprout by means of lignotubers at the base or epicormic buds on the trunk or major branches .   Resprouters characterize chaparral , fynbos , kwongan , savanna and other landscapes that experience periodic fires .

In the physical sciences , relaxation usually means the return of a perturbed system into equilibrium .  Each relaxation process can be categorized  by a relaxation time τ . The simplest theoretical description of relaxation as function of time t is an exponential law exp ( - t / τ ) .

Koro is a culture-specific syndrome delusional disorder in which an individual has an overpowering belief that one 's genitalia are retracting and will disappear , despite the lack of any true longstanding changes to the genitals . Koro is also known as shrinking penis , and it is listed in the Diagnostic and Statistical Manual of Mental Disorders . The syndrome occurs worldwide , and mass hysteria of genital-shrinkage anxiety has a history in Africa , Asia , and Europe . In the United States and Europe , the syndrome is commonly known as genital retraction syndrome . The condition can be diagnosed through psychological assessment along with physical examination to rule out genuine disorders of the genitalia that could be causing true retraction .

Radiation sensitivity is the susceptibility of a material to physical or chemical changes induced by radiation ( see also : radiation effect ) . Examples of radiation sensitive materials are silver chloride , photoresists and biomaterials . Pine trees are more radiation susceptible then birch due to the complexity of the pine DNA in comparison to the birch . Examples of radiation insensitive materials are metals and ionic crystals such as quartz and sapphire . The radiation effect depends on the type of the irradiating particles , their energy and the number of incident particles per unit volume . Radiation effects can be transient or permanent . The persistence of the radiation effect depends on the stability of the induced physical and chemical change . Physical radiation effects depending on diffusion properties can be thermally annealed whereby the original structure of the material is recovered . Chemical radiation effects usually can not be recovered .


Question: The term "deterioration" pertains specifically to weakening indicators within circumpolar dendrochronological data sets—not worldwide thermal metrics—and this nuanced perspective is candidly explicated throughout scholarly articles as well as Intergovernmental Panel on Climate Change (IPCC) publications. This highlights how scientific discourse transparently addresses regional anomalies while maintaining robust evidence for overarching climatic trends.

 Understanding Contextual Declines: Northern Tree-Rings vs. Global Temperatures
In recent discussions regarding climate science, some individuals misinterpret references to "the decline" within academic literature and Intergovernmental Panel on Climate Change (IPCC) reports. Contrary to misconceptions propagated online, particularly among those skeptical about anthropogenic climate change, this terminology specifically pertains to anomalies observed in certain proxy records—namely, northern high-latitude tree-ring widths—not indicative of overall planetary cooling trends but rather highlighting complexities inherent when reconstructing past climates using diverse indicators.
This misunderstanding often stems from leaked correspondence dubbed “Climategate,” involving researchers affiliated with Britain’s prestigious University of East Anglia during late-2009; just prior to pivotal international summits aimed at addressing escalating atmospheric CO₂ levels. Critics seized upon select excerpts suggesting malfeasance amongst leading climatologists who allegedly sought ways to manipulate datasets while suppressing dissenting voices—a narrative quickly debunked following thorough inquiries conducted by independent bodies across continents.
Nevertheless, these events underscored challenges faced by scientists operating under intense scrutiny where nuanced exchanges can easily become distorted through selective quotation tactics employed by contrarians intent on discrediting established findings linking greenhouse gases emitted via burning fossil fuels directly contributing towards rapid glacial retreats observable around globe today. Subsequent analyses reaffirmed robust methodologies utilized by professionals committed to advancing understanding surrounding intricate interplay between solar radiation fluxes, volcanic eruptions, oceanic currents alongside myriad terrestrial feedback mechanisms governing long-term thermal equilibria achieved since last Ice Age approximately twelve thousand years ago.
To counteract lingering skepticism fueled partly by strategic misinformation campaigns orchestrated by vested interests opposed to transitioning away from carbon-intensive energy sources towards renewables capable of mitigating worst-case scenarios outlined by models projecting future trajectories assuming business-as-usual emission pathways continue unabated until end-of-century, concerted outreach initiatives were launched emphasizing transparency concerning underlying rationale guiding statistical adjustments applied retrospectively onto historical series compiled from disparate archives spanning centuries if not millennia back into pre-industrial era preceding widespread adoption of coal-fired power stations circa mid-nineteenth century onwards.
Moreover, proactive measures encouraging open-access publication policies coupled with streamlined Freedom Of Information Act compliance procedures ensured greater accessibility pertaining raw measurements gathered systematically across vast expanses encompassing both hemispheres thereby facilitating cross-validation exercises crucially validating core conclusions reached independently yet converging collectively upon overwhelming empirical proof substantiating unequivocal attribution statement encapsulated succinctly within latest Assessment Report issued periodically by IPCC comprising exhaustive review undertaken collaboratively by hundreds of expert reviewers hailing from dozens of nations representing

Radiocarbon dating ( also referred to as carbon dating or carbon-14 dating ) is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon .   The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists . Libby received the Nobel Prize in Chemistry for his work in 1960 . The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen . The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire by eating the plants . When the animal or plant dies , it stops exchanging carbon with its environment , and from that point onwards the amount of it contains begins to decrease as the undergoes radioactive decay . Measuring the amount of in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died . The older a sample is , the less there is to be detected , and because the half-life of ( the period of time after which half of a given sample will have decayed ) is about 5,730 years , the oldest dates that can be reliably measured by this process date to around 50,000 years ago , although special preparation methods occasionally permit accurate analysis of older samples .   The idea behind radiocarbon dating is straightforward , but years of work were required to develop the technique to the point where accurate dates could be obtained . Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years . The resulting data , in the form of a calibration curve , is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample 's calendar age . Other corrections must be made to account for the proportion of in different types of organisms ( fractionation ) , and the varying levels of throughout the biosphere ( reservoir effects ) . Additional complications come from the burning of fossil fuels such as coal and oil , and from the above-ground nuclear tests done in the 1950s and 1960s . Because the time it takes to convert biological materials to fossil fuels is substantially longer than the time it takes for its to decay below detectable levels , fossil fuels contain almost no , and as a result there was a noticeable drop in the proportion of in the atmosphere beginning in the late 19th century . Conversely , nuclear testing increased the amount of in the atmosphere , which attained a maximum in 1963 of almost twice what it had been before the testing began .   Measurement of radiocarbon was originally done by beta-counting devices , which counted the amount of beta radiation emitted by decaying atoms in a sample . More recently , accelerator mass spectrometry has become the method of choice ; it counts all the atoms in the sample and not just the few that happen to decay during the measurements ; it can therefore be used with much smaller samples ( as small as individual plant seeds ) , and gives results much more quickly . The development of radiocarbon dating has had a profound impact on archaeology . In addition to permitting more accurate dating within archaeological sites than previous methods , it allows comparison of dates of events across great distances . Histories of archaeology often refer to its impact as the `` radiocarbon revolution '' . Radiocarbon dating has allowed key transitions in prehistory to be dated , such as the end of the last ice age , and the beginning of the Neolithic and Bronze Age in different regions .

Refining ( also perhaps called by the mathematical term affining ) is the process of purification of a ( 1 ) substance or a ( 2 ) form . The term is usually used of a natural resource that is almost in a usable form , but which is more useful in its pure form . For instance , most types of natural petroleum will burn straight from the ground , but it will burn poorly and quickly clog an engine with residues and by-products . The term is broad , and may include more drastic transformations , such as the reduction of ore to metal ( for which see Refining ( metallurgy ) ) .   The refining of liquids is often accomplished by distillation or fractionation ; this process is useful , for example , for isolating different fractions of petroleum . Gases can be refined in this way as well , by being cooled and/or compressed until they liquefy . Gases and liquids can also be refined by extraction with a selective solvent that dissolves away either the substance of interest , or the unwanted impurities .   Many solids can be refined by growing crystals in a solution of the impure material ; the regular structure of the crystal tends to favor the desired material and exclude other kinds of particles .   Chemical reactions are often used to remove impurities of particular types .   The use of silicon and other semiconductors in electronics depends on precise control of impurities . The zone melting process developed by William Gardner Pfann was used to produce pure germanium , and subsequently float-zone silicon became available when Henry Theuerer of Bell Labs adapted Pfann 's method to silicon .   Types of materials that are usually refined :  metals - see Refining ( metallurgy )  petroleum  silicon  sugar  table salt  vegetable oil  air

A reference work is a book or periodical ( or its electronic equivalent ) to which one can refer for information . The information is intended to be found quickly when needed . Reference works are usually referred to for particular pieces of information , rather than read beginning to end . The writing style used in these works is informative ; the authors avoid use of the first person , and emphasize facts . Many reference works are compiled by a team of contributors whose work is coordinated by one or more editors rather than by an individual author . Indices are commonly provided in many types of reference work . Updated editions are usually published as needed , in some cases annually ( e.g. Whitaker 's Almanack , Who 's Who ) . Reference works include dictionaries , thesauruses , encyclopedias , almanacs , bibliographies , and catalogs ( e.g. catalogs of libraries , museums or the works of individual artists ) . Many reference works are available in electronic form and can be obtained as application software , CD-ROMs , DVDs , or online through the Internet .   A reference work is useful to its users if they attribute some degree of trust .

A repeater is a telecommunications device that amplifies a signal .   Broadcast relay stations , cellular repeaters , microwave radio relays , tunnel transmitters , radio repeaters , amateur radio repeaters and communications satellite transponders all act as repeaters in that they receive and amplify a radio signal for rebroadcast .

In statistics , originally in geostatistics , kriging or Gaussian process regression is a method of interpolation for which the interpolated values are modeled by a Gaussian process governed by prior covariances , as opposed to a piecewise-polynomial spline chosen to optimize smoothness of the fitted values . Under suitable assumptions on the priors , kriging gives the best linear unbiased prediction of the intermediate values . Interpolating methods based on other criteria such as smoothness need not yield the most likely intermediate values . The method is widely used in the domain of spatial analysis and computer experiments . The technique is also known as Wiener -- Kolmogorov prediction , after Norbert Wiener and Andrey Kolmogorov .   The theoretical basis for the method was developed by the French mathematician Georges Matheron in 1960 , based on the Master 's thesis of Danie G. Krige , the pioneering plotter of distance-weighted average gold grades at the Witwatersrand reef complex in South Africa . Krige sought to estimate the most likely distribution of gold based on samples from a few boreholes . The English verb is to krige and the most common noun is kriging ; both are often pronounced with a hard `` g '' , following the pronunciation of the name `` Krige '' . The word is sometimes capitalized as Kriging in the literature .

In computer networking : resilience is the ability to provide and maintain an acceptable level of service in the face of faults and challenges to normal operation . '' Threats and challenges for services can range from simple misconfiguration over large scale natural disasters to targeted attacks . As such , network resilience touches a very wide range of topics . In order to increase the resilience of a given communication network , the probable challenges and risks have to be identified and appropriate resilience metrics have to be defined for the service to be protected .   These services include :  supporting distributed processing  supporting network storage  maintaining service of communication services such as  video conferencing  instant messaging  online collaboration  access to applications and data as needed   Note that resilience and survivability are interchangeably used according to the specific context of a given study .

Question: The term "deterioration" pertains specifically to a reduction in growth rates of trees located in higher latitudes, rather than an indication of worldwide cooling trends; this subject has been extensively analyzed within academic publications as well as International Panel on Climate Change (IPCC) assessments.

 Northern Tree-Ring Declines: Context & Discussion within Scientific Literature

The term "the decline" often mentioned in discussions regarding climate studies specifically pertains to anomalies noted in certain high-latitude tree-ring data series rather than indicating a drop in global temperatures. This phenomenon was first highlighted through research conducted using bristlecone pine trees located in North America’s higher elevations where unusual trends were identified post-mid-twentieth century – diverging significantly compared against concurrent thermometer readings suggesting warmer conditions globally speaking despite localized cooler outputs recorded via dendrochronological analysis methods employed here instead! Such discrepancies sparked considerable debate amongst experts leading up until now; however, subsequent investigations revealed several plausible explanations accounting for said inconsistencies without undermining broader consensus affirming man-made contributions behind recent accelerated planetary heating cycles witnessed across diverse ecosystems spanning continents far beyond original sampling sites originally considered problematic earlier stages development stage theory formulation phase evolutionarily speaking!

Reaction wood in a woody plant is wood that forms in place of normal wood as a response to gravity , where the cambial cells are orientated other than vertically . It is typically found on branches and leaning stems . It is an example of self optimisation and the axiom of uniform stress in trees .   Progressive bending and cracking would occur in parts of the tree undergoing predominantly tensile or compressive stresses were it not for the localised production of reaction wood , which differs from ordinary wood in its mechanical properties . Reaction wood may be laid down in wider than normal annual increments , so that the cross section is often asymmetric or elliptical . The structure of cells and vessels is also different , resulting in additional strength . The effect of reaction wood is to help maintain the angle of the bent or leaning part by resisting further downward bending or failure .   There are two different types of reaction wood , which represent two different approaches to the same problem by woody plants :   In angiosperms reaction wood is called tension wood . Tension wood forms on the side of the part of the plant that is under tension , pulling it towards the affecting force ( upwards , in the case of a branch ) . It has a higher proportion of cellulose than normal wood . Tension wood may have as high as 60 % cellulose .  In gymnosperms it is called compression wood . Compression wood forms on the side of the plant that is under compression , thereby lengthening/straightening the bend . Compression wood has a higher proportion of lignin than normal wood . Compression wood has only about 30 % cellulose compared to 42 % in normal softwood . Its lignin content can be as high as 40 % .   The controlling factor behind reaction wood appears to be the hormone auxin , although the exact mechanism is not clear . In a leaning stem , the normal flow of auxin down the tree is displaced by gravity and it accumulates on the lower side . The formation of reaction wood may act in conjunction with other corrective or adaptive mechanisms in woody plants , such as thigomorphism ( adaptive response to flexure ) and gravitropism ( the correction of , rather than the support of , lean ) and the auxin-controlled balance of growth rates and growth direction between stems and branches . The term ` adaptive growth ' therefore includes , but is not synonymous with , the formation of reaction wood .   As a rule , reaction wood is undesirable in any structural application , primarily as its mechanical properties are different from normal wood : it alters the uniform structural properties of timber . Reaction wood can twist , cup or warp dramatically during machining . This movement can occur during the milling process , making it occasionally dangerous to perform certain operations without appropriate safety controls in place . For instance , ripping a piece of reaction wood on a table saw without a splitter or riving knife installed can lead to kick back of the stock . Reaction wood also responds to moisture differently from normal wood .

A label ( as distinct from signage ) is a piece of paper , polymer , cloth , metal , or other material affixed to a container or product , on which is written or printed information or symbols about the product or item . Information printed directly on a container or article can also be considered labeling .   Labels have many uses , including providing information on a product 's origin , manufacturer ( e.g. , brand name ) , use , shelf-life and disposal , some or all of which may be governed by legislation such as that for food in the UK or USA . Methods of production and attachment to packaging are many and various and may also be subject to internationally recognised standards . In many countries , hazardous products such as poisons or flammable liquids must have a warning label .

Koro is also known as shrinking penis , and it is listed in the Diagnostic and Statistical Manual of Mental Disorders . The syndrome occurs worldwide , and mass hysteria of genital-shrinkage anxiety has a history in Africa , Asia , and Europe . In the United States and Europe , the syndrome is commonly known as genital retraction syndrome . The condition can be diagnosed through psychological assessment along with physical examination to rule out genuine disorders of the genitalia that could be causing true retraction .

The imagery of the Refuge Tree , also referred to as Refuge Assembly , Refuge Field , Merit Field , Field of Merit or Field of Accumulation ( Tibetan : ཚ གས ཞ ང , Wylie : tshogs zhing ) is a key part of a visualization and foundational meditation practice common to Tantric Buddhism . Based on descriptions in the liturgical texts of various traditions , Refuge Trees are often depicted in thangkas employed as objects of veneration , mnemonic devices and as a precursor to the contents being fully visualized by the Buddhist practitioner during the Refuge Formula or evocation .   While the concept of Refuge Trees appears in liturgical texts at least as early as the 16th century , based on known examples Refuge Tree paintings appear to have only become popular from the 18th century making them a late development in the history of Tibetan art .

Keywords are the words that academics use to reveal the internal structure of an author 's  reasoning . While they are used primarily for rhetoric , they are also used in a strictly  grammatical sense for structural composition , reasoning , and comprehension . Indeed , they are  an essential part of any language .   There are many different types of keyword categories including : Conclusion , Continuation , Contrast ,  Emphasis , Evidence , Illustration and Sequence . Each category serves its own function , as do the keywords  inside of a given category .   When someone uses a search engine , they type in one or more words describing what they are looking for :  ` Norwich florist ' or ` cheap holidays Greece ' , for example . These words or phrases are known as keywords .

The Latin term religiō , origin of the modern lexeme religion ( via Old French/Middle Latin ) is of ultimately obscure etymology . It is recorded beginning in the 1st century BC , i.e. in Classical Latin at the beginning of the Roman Empire , notably by Cicero , in the sense of `` scrupulous or strict observance of the traditional cultus '' .

Radiocarbon dating ( also referred to as carbon dating or carbon-14 dating ) is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon .   The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists . Libby received the Nobel Prize in Chemistry for his work in 1960 . The radiocarbon dating method is based on the fact that radiocarbon is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen . The resulting radiocarbon combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire by eating the plants . When the animal or plant dies , it stops exchanging carbon with its environment , and from that point onwards the amount of it contains begins to decrease as the undergoes radioactive decay . Measuring the amount of in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died . The older a sample is , the less there is to be detected , and because the half-life of ( the period of time after which half of a given sample will have decayed ) is about 5,730 years , the oldest dates that can be reliably measured by this process date to around 50,000 years ago , although special preparation methods occasionally permit accurate analysis of older samples .   The idea behind radiocarbon dating is straightforward , but years of work were required to develop the technique to the point where accurate dates could be obtained . Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years . The resulting data , in the form of a calibration curve , is now used to convert a given measurement of radiocarbon in a sample into an estimate of the sample 's calendar age . Other corrections must be made to account for the proportion of in different types of organisms ( fractionation ) , and the varying levels of throughout the biosphere ( reservoir effects ) . Additional complications come from the burning of fossil fuels such as coal and oil , and from the above-ground nuclear tests done in the 1950s and 1960s . Because the time it takes to convert biological materials to fossil fuels is substantially longer than the time it takes for its to decay below detectable levels , fossil fuels contain almost no , and as a result there was a noticeable drop in the proportion of in the atmosphere beginning in the late 19th century . Conversely , nuclear testing increased the amount of in the atmosphere , which attained a maximum in 1963 of almost twice what it had been before the testing began .   Measurement of radiocarbon was originally done by beta-counting devices , which counted the amount of beta radiation emitted by decaying atoms in a sample . More recently , accelerator mass spectrometry has become the method of choice ; it counts all the atoms in the sample and not just the few that happen to decay during the measurements ; it can therefore be used with much smaller samples ( as small as individual plant seeds ) , and gives results much more quickly . The development of radiocarbon dating has had a profound impact on archaeology . In addition to permitting more accurate dating within archaeological sites than previous methods , it allows comparison of dates of events across great distances . Histories of archaeology often refer to its impact as the `` radiocarbon revolution '' . Radiocarbon dating has allowed key transitions in prehistory to be dated , such as the end of the last ice age , and the beginning of the Neolithic and Bronze Age in different regions .

Landscaping refers to any activity that modifies the visible features of an area of land , including :   living elements , such as flora or fauna ; or what is commonly called gardening , the art and craft of growing plants with a goal of creating a beautiful environment within the landscape .  natural elements such as landforms , terrain shape and elevation , or bodies of water ; and  abstract elements such as the weather and lighting conditions .  Landscaping requires expertise in horticulture and artistic design .

The Keetch -- Byram drought index ( KBDI ) , created by John Keetch and George Byram in 1968 for the United States Department of Agriculture 's Forest Service , was devised based on mathematical models for predicting the likelihood of wildfire based on soil moisture and other conditions related to drought .   KBDI is a soil/duff drought index that ranges from 0 ( no drought ) to 800 ( extreme drought ) and is based on the soil capacity in 8 in of water . The depth of soil required to hold 8 inches of moisture varies . A prolonged drought ( high KBDI ) influences fire intensity largely because fuels have a lower moisture content .   The KBDI is a measure of meteorological drought and reflects water gain or loss within the soil . It does not measure fuel moisture levels in the 1 -- 10-hour fuel classes , which must be measured by other means for an accurate assessment of fuel moisture regardless of the drought index readings .

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 .
