Question: Prior to the onset of anthropogenic greenhouse gas emissions leading to climate change, Antarctica's glacial mass had maintained an equilibrium state for centuries. This alteration has significantly disrupted natural cycles within this pristine environment, causing rapid melting that threatens coastal regions worldwide with rising sea levels.

Antarctica Ice Sheet Stability Prior to Industrial Era
Before significant human interference through extensive fossil fuel combustion instigated global warming trends, Antarctic ice sheets maintained comparative equilibrium within historical norms. These vast expanses of frozen terrain served crucial roles in regulating regional climates and ocean currents. However, since the onset of widespread industrialization, increased atmospheric temperatures have disrupted this delicate stability. Carbon-intensive practices, particularly those involving coal utilization for power generation and heating, contribute significantly to rising CO2 levels. Over centuries, organic material transformed under high pressure and temperature conditions into various types of coal - ranging from low-grade lignite to higher-quality anthracite. Historically, humans relied heavily upon coal as both an essential energy commodity and key ingredient in metal processing industries. Yet, despite its economic importance, coal exploitation comes with substantial ecological costs: air pollutants linked to respiratory diseases; acid rain damaging ecosystems; particulate emissions exacerbating smog issues; plus notable contributions to global warming via enhanced greenhouse effect mechanisms. Among major coal-producing nations, China leads globally, followed closely behind by USA, India, EU bloc countries, alongside Australian output figures. Export dynamics reveal Australia commanding market shares around 27%, whereas Indonesian shipments account roughly equivalent proportions nearing quarter-century mark statistics-wise. Importantly though, Japan tops list importing nearly fifth portion volumes consumed annually across borders compared Chinese counterparts absorbing slightly lesser fractions overall pie chart representation wise too!

Question: Prior to anthropogenic combustion of carbon-based resources instigating climate change, the region's frozen terrain maintained an equilibrium state. This suggests that before humans started using large amounts of coal, oil, and gas - activities which have led to increased greenhouse gases and subsequent planetary heating - there existed stability within continental glaciated areas.

 Antarctic Ice Sheet Stability Prior to Anthropogenic Influence

Before the onset of widespread fossil fuel combustion and subsequent global warming, Antarctica's vast ice sheet maintained a state of dynamic equilibrium within historical norms. Throughout millennia, this colossal frozen reservoir played a crucial role in regulating global temperatures through albedo reflection and influencing oceanic circulation patterns. However, recent studies reveal alarming trends indicating that human-driven climate change threatens this delicate stability.

Historically, fluctuations in atmospheric conditions and solar radiation governed glacial cycles without triggering catastrophic shifts. Yet, contemporary data suggests a stark departure: rapid ice mass loss attributed directly to escalating global temperatures. Satellite imagery confirms accelerating glacier calving along coastal regions, particularly evident in West Antarctica where Thwaites Glacier exhibits signs of irreversible destabilization.

The Intergovernmental Panel on Climate Change (IPCC) underscores the pivotal link between greenhouse gas concentrations—primarily carbon dioxide—and accelerated ice melt across polar territories. Projections estimate substantial contributions to sea-level rise if current trajectories continue unchecked; scenarios range widely depending upon mitigative actions taken globally.

Antarctica serves as both sentinel and victim under intensifying thermal stressors imposed by anthropocentric practices. Its fate intertwines intimately with planetary health, impacting marine ecosystems, freshwater availability, and habitability for billions inhabiting low-elevation zones susceptible to inundation. Adaptation strategies necessitate robust monitoring networks coupled with proactive conservation measures aimed at preserving critical ice masses while addressing root causes systematically.

Public awareness regarding Antarctic vulnerabilities remains nascent yet growing, paralleled by mounting pressure on policymakers to enact stringent regulations curtailing GHG outputs. Collaborative initiatives spanning governmental bodies, research institutions, NGOs, and private sectors underscore collective commitment requisite for safeguarding Earth's last pristine wilderness against looming threats posed by unbridled development agendas.

In summary, prior to humanity's intervention via excessive reliance on non-renewable energy sources, Antarctica's ice shield endured relatively stable phases reflective of broader geophysical rhythms. Today, however, urgent action is imperative lest we witness irrevocable damage inflicted upon this vital component of terrestrial ecology.

In English common law , real property , real estate , realty , or immovable property is land which is the property of some person and all structures ( also called improvements or fixtures ) integrated with or affixed to the land , including crops , buildings , machinery , wells , dams , ponds , mines , canals , and roads , among other things . The term is historic , arising from the now-discontinued form of action , which distinguished between real property disputes and personal property disputes . Personal property was , and continues to be , all property that is not real property .   In countries with personal ownership of real property , civil law protects the status of real property in real-estate markets , where estate agents work in the market of buying and selling real estate . Scottish civil law calls real property `` heritable property '' , and in French-based law , it is called immobilier ( `` immovable property '' ) .

Rainey 's Cabin , also known as Skarland 's Cabin and Ivar 's Cabin , is a historic log cabin on the campus of the University of Alaska Fairbanks in College , Alaska . It is a single-story three-room log structure , with a massive central stone fireplace . The cabin was built in 1939 for Froelich Rainey , the first chairman of the university 's anthropology department . The cabin for many years played a significant role as a social center of the university , and was where Rainey hosted a number of pioneering archaeologists and anthropologists , including J. Louis Giddings and Frederica de Laguna . The cabin was later occupied by Ivar Skarland , who succeeded to Rainey 's chair and continued his social practices . The university uses the cabin as housing for anthropology and archaeology professors and students .

The 1988 Armenian earthquake , also known as the Spitak earthquake ( Սպիտակի երկրաշարժ Spitaki yerkrašarž ) , occurred on December 7 at with a surface wave magnitude of 6.8 and a maximum MSK intensity of X ( Devastating ) . The shock occurred in the northern region of Armenia ( then part of the Soviet Union ) which is vulnerable to large and destructive earthquakes and is part of a larger active seismic belt that stretches from the Alps to the Himalayas . Activity in the area is associated with tectonic plate boundary interaction and the source of the event was slip on a thrust fault just to the north of Spitak . The complex incident ruptured multiple faults , with a strike-slip event occurring shortly after the initiation of the mainshock . Between 25,000 and 50,000 were killed and up to 130,000 were injured .   Seismologists thoroughly studied the effects of the Spitak event , including the mainshock and aftershock fault rupture mechanisms and were on site setting up temporary seismometers before the end of 1988 . Earthquake engineering experts scrutinized building construction styles and found fault in the poorly constructed apartments and other buildings that were built during the Era of Stagnation under the rule of Leonid Brezhnev . The cities of Spitak , Leninakan ( Gyumri ) , and Kirovakan ( Vanadzor ) were greatly affected with large losses of life and devastating effects to buildings and other structures . A number of the smaller outlying villages away from the larger population centers were also severely affected .   Despite the tensions of the Cold War , Soviet leader Mikhail Gorbachev formally asked the United States for humanitarian help within a few days of the earthquake , the first such request since World War II . One hundred and thirteen countries sent substantial amounts of humanitarian aid to the Soviet Union in the form of rescue equipment , search teams and medical supplies , but private donations and assistance from non-governmental organizations also had a large part of the international effort . While transporting some of these supplies to the region , a Soviet aircraft carrying 9 crew members and 69 military personnel and a transport plane from Yugoslavia were both destroyed in separate incidents . In support of the relief effort , recording artists united to produce several music-related contributions for the victims of the quake . A song was produced by a duo of French composers ( including Charles Aznavour ) and a studio album that featured songs donated by mainstream rock bands was released from the Rock Aid Armenia effort by the British music industry .

The Richter Glacier is a low gradient coastal glacier located 18 km west of the Scott Nunataks on the northern side of Edward VII Peninsula . The feature saddles with the Butler Glacier and flows north-west to the sea where it forms a small tongue . The glacier and tongue are depicted on the map of the Byrd Antarctic Expedition , 1928-30 . The map indicates that the landing party from the Kainan Maru ( Shirase ) traversed up this glacier to the summit of the Scott Nunataks in January 1912 . The glacier was mapped in detail by the United States Geological Survey ( USGS ) from ground surveys and US Navy aerial photographs , 1959-65 . It was named by the Advisory Committee on Antarctic Names ( US-ACAN ) for Gregory S. Richter , meteorologist-in-charge and scientific leader of the Byrd Station winter party in 1968 .

It is a significant aquifer in some areas , and its conglomerates yielded significant quantities of gold in the Black Hills of South Dakota .   It preserves trace fossils such as Skolithos , and remains of Late Cambrian trilobites and brachiopods , as well as Ordovician fossils .

Larsen Harbour is a narrow 2.6 mi long inlet of indenting volcanic rocks and sheeted dykes known as the Larsen Harbour Formation . It is a branch of Drygalski Fjord , entered 2.5 mi west-northwest of Nattriss Head , at the southeast end of South Georgia . It was charted by the German Antarctic Expedition , 1911 -- 12 , under Filchner , who named it for Captain Carl Anton Larsen a Norwegian Antarctic Explorer , who made significant contributions to the exploration of Antarctica . The most significant being the first discovery of fossils , for which he received the Back Grant from the Royal Geographical Society . Larsen is also considered the founder of the Antarctic whaling industry and the settlement at Grytviken , South Georgia .   The peaks and mountain crests surrounding the almost land-locked harbour was described by Sir Ernest Shackleton 's photographer Frank Hurley as `` most beautiful and exceeding all in grandeur even that of Milford Sound '' .   The Niall Rankin expedition aboard the Albatross , spent some time here as they studied the Weddell seal colony before going on to Esbensen Bay .   The area is rat-free , allowing species such as the South Georgia pipit , and burrowing petrels and prions to thrive . Mountains descend steeply into the sea here , and various glaciers calve into the sea .

The Kolyma Lowland is a lowland plain in the northwestern parts of Sakha Republic in the basin of the Alazeya , Bolshaya Chukoch ` ya and lower reaches of the Kolyma rivers . It stretches for 750 km along the Kolyma River from East Siberian Sea to the Chersky Range , between the Alazeya and Yukagir plateaus . The average height of the Kolyma lowland is 100 m with occasional peaks up to 300 m high . The lowland is formed by fluvio-lacustrine loam soil about 120 m thick . The climate is subarctic .

Debris flows are geological phenomena in which water-laden masses of soil and fragmented rock rush down mountainsides , funnel into stream channels , entrain objects in their paths , and form thick , muddy deposits on valley floors . They generally have bulk densities comparable to those of rock avalanches and other types of landslides ( roughly 2000 kilograms per cubic meter ) , but owing to widespread sediment liquefaction caused by high pore-fluid pressures , they can flow almost as fluidly as water . Debris flows descending steep channels commonly attain speeds that surpass 10 meters per second ( more than 20 miles per hour ) , although some large flows can reach speeds that are much greater . Debris flows with volumes ranging up to about 100,000 cubic meters occur frequently in mountainous regions worldwide . The largest prehistoric flows have had volumes exceeding 1 billion cubic meters ( i.e. , 1 cubic kilometer ) . As a result of their high sediment concentrations and mobility , debris flows can be very destructive .   Notable debris-flow disasters of the twentieth century involved more than 20,000 fatalities in Armero , Colombia in 1985 and tens of thousands in Vargas State , Venezuela in 1999 .

A ribbon lake is a long and narrow , finger-shaped lake , usually found in a glacial trough . Its formation begins when a glacier moves over an area containing alternate bands of hard and soft bedrock . The sharp-edged boulders that are picked up by the glacier and carried at the bottom of the glacier erode the softer rock more quickly by abrasion , thus creating a hollow called a rock basin . On either side of the rock basin , the more resistant rock is eroded less and these outcrops of harder rock are known as rock bars , which act as dams between which rainwater may accumulate after the retreat of the ice age , filling up the rock basin and creating a ribbon lake .   A ribbon lake may also form behind a terminal or recessional moraine , both of which also act as dams , enabling water to accumulate behind them .   A ribbon lake may also occur if a tributary glacier joins a main glacier . The increase in power can create a trough , which is filled with water from a river/meltwater to create a ribbon lake .   A ribbon lake is one of a number of glacial landscapes . These include arêtes , corries , rock lips , rock basins and terminal moraines .   Examples of ribbon lakes are : Windermere , Panguipulli , Coniston Water , Lake Washington , Wastwater , and Llyn Ogwen .


Question: Prior to the onset of anthropogenic greenhouse gas emissions leading to climate change, Antarctica's icy terrain maintained an equilibrium state relatively undisturbed by external forces.

 Pre-Industrial Climate Stability
Prior to significant human influence through fossil fuel combustion, Antarctica experienced a relatively stable climate equilibrium characterized by balanced ice dynamics. During pre-industrial times, before substantial anthropogenic interference, the vast ice sheets covering the continent were maintained within narrow thermal margins, ensuring minimal net gain or loss year-round. These conditions allowed ancient ecosystems to thrive alongside expansive ice formations without drastic fluctuations typical of current rapid changes induced by global warming. Notably, this stability persisted throughout several millennia until recent centuries when escalating carbon dioxide levels disrupted longstanding climactic norms. Understanding past climates helps contextualize contemporary challenges posed by accelerated ice melts and highlights urgent need for sustainable practices mitigating future impacts.
The reference text discusses how prior to widespread use of fossil fuels leading up to modern era global warming trends, Antarctica had been experiencing consistent temperatures maintaining its massive ice sheet coverage across thousands upon thousands of years uninterrupted; highlighting just how drastically things changed once humans started significantly contributing CO₂ into earth's atmosphere causing dramatic shifts away from historical normative behavior exhibited during previous eras devoid any sort major external perturbations capable inducing comparable scale alterations observed presently day-to-day life around globe especially concerning rapidly disappearing cryosphere components like glaciers & sea ice packs etc...which raises serious concerns regarding overall planetary health going forward unless swift action taken soon enough reverse course back towards more hospitable living environments conducive supporting diverse range flora fauna alike!

The Democratic Republic of the Congo ( -LSB- ˈkɒŋɡəʊ -RSB- -LSB- kɔ̃ɡo -RSB- ; République démocratique du Congo ) , also known as DR Congo , DRC , DROC , Congo-Kinshasa or simply the Congo , is a country located in Central Africa . The DRC borders the Central African Republic and South Sudan to the north ; Uganda , Rwanda , Burundi and Tanzania to the east ; Zambia and Angola to the south ; the Republic of the Congo to the west and the Atlantic Ocean to the southwest . It is the second-largest country in Africa by area and eleventh largest in the world . With a population of over 80 million , the Democratic Republic of the Congo is the most populated officially Francophone country , the fourth most-populated nation in Africa and the eighteenth most populated country in the world .   The territory of the DR Congo was first settled by humans around 90,000 years ago . Bantu peoples began migrating into the region in the 5th century and again in the 10th century . In the West of the region the Kingdom of Kongo ruled from the 14th to 19th centuries , while in the centre and East of the region the kingdoms of Luba and Lunda ruled from the 16th and 17th centuries to the 19th century . In the 1870s , before the onset of the Scramble for Africa , European exploration of the Congo was carried out , first led by Sir Henry Morton Stanley under the sponsorship of King Leopold II of Belgium . Leopold formally acquired rights to the Congo territory at the Conference of Berlin in 1885 and made the land his private property . He named it the Congo Free State . During the Free State the colonial military unit , the Force Publique , forced the local population into producing rubber , and from 1885 to 1908 millions of Congolese died as a consequence of disease and exploitation . In 1908 Belgium , despite initial reluctance , formally annexed the Free State from Leopold , which became the Belgian Congo .   The Belgian Congo achieved independence on 30 June 1960 under the name Republic of the Congo ( Léopoldville ) . Congolese nationalist Patrice Lumumba was elected the first Prime Minister , while Joseph Kasa-Vubu became the first President . Conflict arose over the administration of the territory which became known as the Congo Crisis . The provinces of Katanga , under Moïse Tshombe , and South Kasai attempted to secede from the Congo . On 5 September 1960 , Kasa-Vubu dismissed Lumumba from office , encouraged by the United States and Belgium after Lumumba turned to the Soviet Union for assistance in the crisis . On 14 September , with U.S. and Belgian support , Lumumba was arrested by forces loyal to Army Chief of Staff Joseph-Désiré Mobutu , who had gained de facto control over the country through a coup d'état the same day , and on 17 January 1961 Lumumba was handed over to Katangan authorities and executed by Belgian-led Katangese troops .   In 1965 Joseph-Désiré Mobutu , who later renamed himself Mobutu Sese Seko , officially came into power through a second coup . In 1971 he renamed the country Zaire . The country was run as a one-party state with his Popular Movement of the Revolution as the sole legal party . Mobutu 's government received considerable support from the United States for its anti-communist stance during the Cold War . By the early 1990s Mobutu 's government began to weaken . Disenfranchisement of the eastern Congolese Tutsi population led to a 1996 invasion led by Tutsi-ruled Rwanda , which began the First Congo War . On 17 May 1997 Laurent-Désiré Kabila , a leader of Tutsi forces from the province of South Kivu , became President , bringing about the end of Mobutu 's 32-year rule . Tensions between President Kabila and the Rwandan and Tutsi presence in the country led to the Second Congo War from 1998 to 2003 . Ultimately , nine African countries and around twenty armed groups became involved in the war , which resulted in the deaths of 5.4 million people . The two wars together devastated the country . President Laurent-Désiré Kabila was assassinated by one of his bodyguards on 16 January 2001 and was succeeded eight days later as President by his son Joseph Kabila .   The Democratic Republic of Congo is extremely rich in natural resources but has had political instability , a lack of infrastructure , issues with corruption and centuries of both commercial and colonial extraction and exploitation with little holistic development . Besides the capital Kinshasa , the two next largest cities Lubumbashi and Mbuji-Mayi are both mining communities . DR Congo 's largest export is raw minerals , with China accepting over 50 % of DRC 's exports in 2012 . , according to the Human Development Index ( HDI ) , DR Congo 's level of human development ranks 176 out of 187 countries .

Question: The potential for significantly higher-than-anticipated sea level increases over the coming decades has become more likely as new research reveals the destabilizing effects of marine ice cliffs on Antarctica's glaciers compared to what was estimated in previous studies from just half-a-decade earlier. This alarming development underscores how rapidly our understanding about climate change impacts can evolve with ongoing scientific investigation into previously unexplored mechanisms like this one involving subaqueous glacial front collapse dynamics leading directly towards accelerated meltwater discharge rates far exceeding conservative projections made under older modeling paradigms lacking such detailed process representation capabilities at their core physics engine layer architecture design stage during formulation phases when initial parameterizations were set forth without benefitting yet from these latest empirical findings now available today thanks largely but not exclusively through satellite remote sensing technology advancements coupled together seamlessly alongside ground truth validation campaigns conducted across multiple spatial scales ranging all way down even up close personal encounters right there onsite where nature itself speaks loudest volumes indeed by showing us firsthand exactly what happens whenever tipping points get crossed triggering irreversible feedback loops capable unleashing forces beyond anyone’s wildest dreams let alone worst nightmares come true overnight almost literally speaking here folks so buckle seatbelts everyone because things could start getting really interesting real fast around planet Earth very soon unless drastic action taken immediately mitigate greenhouse gas emissions globally ASAP before time runs completely out altogether leaving nothing left whatsoever except perhaps memories fading away slowly into oblivion along winds blowing gently across barren landscapes devoid life forms once thrived abundantly everywhere eyesight reached back then long gone era seemingly lost forevermore beneath waves crashing relentlessly upon shores eroded mercilessly year after relentless passing millennia stretching endlessly forward ad infinitum eternally boundless void awaiting patiently arrival final chapter humanity story written stars above shining brightly night sky reminding constantly fleeting mortal existence compared vast cosmic scale grand scheme things ultimately insignificant speck dust floating aimlessly infinite universe waiting eagerly consume utterly whole eventually sooner rather later inevitable fate awaits us all regardless choices make meantime still alive kicking fighting tooth nail preserve precious gift given birthright bestowed freely every single living creature ever existed since beginning times immemorial past present future alike united common cause survival against odds stacked heavily against success nevertheless persisting dogged determination never give hope despite overwhelming adversity faced daily basis throughout history mankind persevered overcome countless challenges thrown path always rising phoenix ashes stronger wiser ready face whatever comes next head held high dignity grace courageously stepping boldly unknown armed knowledge gained experience wisdom passed generations ensuring legacy endures perpetually timeless testament indomitable spirit human race defies logic reason transcends boundaries divides binds tightly fabric society together making possible dream impossible dreamer dared

 Accelerated Sea Level Rise: Implications for Coastal Areas
Recent studies indicate that projections regarding future sea level rise could surpass previous estimations significantly, particularly when considering phenomena such as marine ice cliff instability. This mechanism involves the rapid disintegration of glacial fronts once they reach seawater, leading to accelerated ice sheet collapse. Consequently, scenarios for sea level increases throughout the coming century now appear substantially higher compared to predictions made just half a decade earlier.

The impact of rising seas extends beyond mere numerical changes; it directly threatens communities residing along coastlines and inhabitants of low-lying islands globally. These areas face increased vulnerability to flooding, storm surges, saltwater intrusion into freshwater sources, and loss of habitable land. Additionally, marine ecosystems suffer disruptions affecting biodiversity and ecological balance. Moreover, local variations in actual sea level rise often exceed averages due to regional factors encompassing geologic movements, oceanic circulation alterations, and weather events intensity.

Scientists warn about ongoing sea level elevation persisting well past current generations given existing commitments under projected temperatures. Even if stringent measures curb greenhouse gases immediately, models suggest unavoidable additional meters of rise spread across millennia - estimates propose around two-point-three (2.3) meters per every single-degree centigrade increment lasting up till year twenty-two hundred (~2200). Such figures underscore urgent need for adaptation strategies alongside mitigation efforts targeting root causes behind escalating planetary warmth.

In summary, contemporary research reveals heightened risks associated with sea level escalation exacerbated through mechanisms akin to marine ice cliffs' destabilization. Immediate action remains imperative both mitigating contributing elements while preparing vulnerable zones against impending inundation challenges anticipated ahead.

Late antiquity is a periodization used by historians to describe the time of transition from classical antiquity to the Middle Ages in mainland Europe , the Mediterranean world , and the Near East . The development of the periodization has generally been accredited to historian Peter Brown , after the publication of his seminal work The World of Late Antiquity ( 1971 ) . Precise boundaries for the period are a continuing matter of debate , but Brown proposes a period between the 3rd and 8th centuries AD . Generally , it can be thought of as from the end of the Roman Empire 's Crisis of the Third Century ( c. 235 -- 284 ) to , in the East , the early Islamic period ( 7th -- 9th centuries ) , following the Muslim conquests in the mid -- 7th century . In the West the end was earlier , with the start of the Early Medieval period typically placed in the 6th century , or earlier on the Western edges of the empire .   The Roman Empire underwent considerable social , cultural and organizational changes starting with the reign of Diocletian , who began the custom of splitting the Empire into Eastern and Western halves ruled by multiple emperors . Beginning with Constantine the Great , Christianity was made legal in the Empire , and a new capital was founded at Constantinople . Migrations of Germanic tribes disrupted Roman rule from the late 4th century onwards , culminating in the eventual collapse of the Empire in the West in 476 , replaced by the so-called barbarian kingdoms . The resultant cultural fusion of Greco-Roman , Germanic and Christian traditions formed the foundations of the subsequent culture of Europe .   The general decline of population , technological knowledge and standards of living in Europe during this period became the archetypal example of societal collapse for writers from the Renaissance until recent times . As a result of this decline , and the relative scarcity of historical records from Europe in particular , the period between the fall of the Empire and the Middle Ages became known as the `` Dark Ages '' , a term displaced in most current periodisations by the introduction of `` Late Antiquity '' .

Random Hills are a group of rugged hills in Victoria Land , Antarctica . Bounded on the west by Campbell Glacier and on the east by Tinker Glacier and Wood Bay , centered about 15 nautical miles ( 28 km ) north-northwest of Mount Melbourne , they were named by the Southern Party of the New Zealand Geological Survey Antarctic Expedition ( NZGSAE ) , 1966 -- 67 , because of the random orientation of the ridges which comprise the feature .

The last glacial period , popularly known as the Ice Age , was the most recent glacial period , which occurred from years ago . This most recent glacial period is part of a larger pattern of glacial and interglacial periods known as the Quaternary glaciation ( years ago to present ) . From this point of view , scientists consider this `` ice age '' to be merely the latest glaciation event in a much larger ice age , one that dates back over two million years and is still ongoing .   During this last glacial period , there were several changes between glacier advance and retreat . The Last Glacial Maximum , the maximum extent of glaciation within the last glacial period , was approximately 22,000 years ago . While the general pattern of global cooling and glacier advance was similar , local differences in the development of glacier advance and retreat make it difficult to compare the details from continent to continent ( see picture of ice core data below for differences ) . Approximately 13,000 years ago , the Late Glacial Maximum began . Around 11,700 years ago marked the beginning of the Holocene geological epoch , which includes the Holocene glacial retreat .   From the point of view of human archaeology , it falls in the Paleolithic and Mesolithic periods . When the glaciation event started , Homo sapiens were confined to Africa and used tools comparable to those used by Neanderthals in western and central Eurasia and by Homo erectus in Asia . Near the end of the event , Homo sapiens spread into Eurasia and Australia . Archaeological and genetic data suggest that the source populations of Paleolithic humans survived the last glacial period in sparsely wooded areas and dispersed through areas of high primary productivity while avoiding dense forest cover . The retreat of the glaciers allowed groups of humans from Asia to migrate to the Americas and populate them .

Richard Irving `` Dick '' Walcott ( born 1933 ) is a New Zealand geologist known for his work on plate tectonics .   Walcott studied at Victoria University College , graduating with a BSc in 1962 . He then completed his PhD at Victoria University of Wellington in 1965 and was awarded a DSc by thesis from the same institution in 1981 . In 1966 he took up a postdoctoral research position at the University of British Columbia and the following year began working at the gravity division of Energy , Mines and Resources Canada . He returned to New Zealand in 1975 , became professor of geology at Victoria in 1983 , retired in 1999 , and was granted the title of emeritus professor .   He was elected a Fellow of the Royal Society of New Zealand in 1982 , and a Fellow of the Royal Society in 1991 . In 1993 he won the Royal Society of New Zealand 's Hector Medal , and in 1999 he was awarded the Charles A. Whitten Medal by the American Geophysical Union .   The Walcott Névé in the Ross Dependency was named for Walcott by the northern party of the New Zealand Geological Survey Antarctic Expedition in 1961 -- 62 , of which he was the leader .

Kohler Dome is a rounded , snow-covered elevation at 2,680 m that rises slightly above the general level of the extreme eastern part of the Mount Moulton massif , in Marie Byrd Land , Antarctica . It was mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos , 1959 -- 66 . The Advisory Committee on Antarctic Names named the formation after Robert E. Kohler of the U.S. Coast and Geodetic Survey , a geomagnetist/seismologist at Byrd Station , 1970 .

Rachel Glacier is a glacier on the east coast of Graham Land , 6 nautical miles ( 11 km ) long , flowing east between Krupen Ridge and Padesh Ridge to enter Exasperation Inlet southwest of Mihaylovski Crag . The name , applied by United Kingdom Antarctic Place-Names Committee ( UK-APC ) , is taken from Herman Melville 's Moby Dick , the Rachel being a ship from Nantucket which met the Pequod and brought news of a lost whaleboat .   Category : Glaciers of Graham Land  Category : Oscar II Coast

Kruber Rock is a lone rock lying 3.5 nmi west-northwest of the summit of Mount Flånuten on the west side of the Humboldt Mountains , in Queen Maud Land , Antarctica . It was discovered and plotted from air photos by the Third German Antarctic Expedition , 1938 -- 39 , and mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition , 1956 -- 60 . The rock was remapped by the Soviet Antarctic Expedition , 1960 -- 61 , and named after Soviet geographer Alexander Kruber .

Radian Glacier is a glacier on the east side of the Royal Society Range , descending from a high cirque just southeast of Mount Rucker and flowing east toward Walcott Glacier . In the measurements made of this glacier by the Victoria University of Wellington Antarctic Expedition ( VUWAE ) ( 1960 -- 61 ) , one of the survey angles , by chance , was exactly one radian , and the glacier came to be referred to by this term .   Radian Ridge is a ridge named in association with Radian Glacier .

( also written 2013 BP73 ) is an Apollo near-Earth asteroid and potentially hazardous object . From discovery until August 2013 when Sentry updated to planetary ephemeris ( DE431 ) , it had the 4th highest impact threat on the Palermo Technical Impact Hazard Scale . It was discovered on 22 January 2013 by the Mount Lemmon Survey at an apparent magnitude of 21 using a 1.5 m reflecting telescope . It has an estimated diameter of 310 m. Six Precovery images from April 2003 have been located . It was removed from the Sentry Risk Table on 3 January 2014 .   It has an observation arc of 10 years with an uncertainty parameter of 2 . Perturbations by Earth , Venus , and Mercury will increase the orbital uncertainty over time . When the asteroid only had an observation arc of 52 days , virtual clones of the asteroid that fit the uncertainty region in the known trajectory showed a 1 in 588,000 chance that the asteroid could impact Earth on 11 December 2096 . With a 2096 Palermo Technical Scale of − 3.42 , the odds of impact by in 2096 were about 2630 times less than the background hazard level of Earth impacts which is defined as the average risk posed by objects of the same size or larger over the years until the date of the potential impact . Using the nominal orbit , JPL Horizons shows that the asteroid will be 0.9 AU from Earth on 11 December 2096 . will make a close approach to Earth on 17 December 2018 that should allow a refinement to the known trajectory .

The Larsemann Hills are a series of low rounded coastal hills along the southeastern shore of Prydz Bay , Antarctica extending for 9 nmi from Dålk Glacier . They were discovered in February 1935 by Captain Klarius Mikkelsen from the whaling ship Thorshavn , sent out by Norwegian whaling magnate Lars Christensen , and given this name .


Question:
 The potential for significantly higher-than-anticipated sea level increases over the coming decades has become more likely due to recent discoveries regarding the vulnerability of marine ice cliffs, compared to our understanding from half-a-decade to a decade earlier. This suggests that projections made just several years back may have underestimated future coastal inundation risks substantially.

 Marine Ice Cliff Instability: Implications for Sea-Level Rise
Recent studies suggest that the impact of marine ice cliff instability could lead to significantly higher sea-level rises within the coming century compared to previous predictions just a decade ago. This phenomenon occurs when glacial cliffs exposed to seawater become unstable under warmer conditions, causing rapid disintegration and contributing disproportionately to sea level increases.

The Intergovernmental Panel on Climate Change (IPCC) acknowledges growing concerns regarding accelerated ice sheet collapse in Greenland and Antarctica, directly linked to ongoing global warming trends. Anthropogenic influences—primarily through increased atmospheric concentrations of greenhouse gases—are identified as key drivers behind escalating temperatures and subsequent ice shelf destabilization. Projections indicate that without substantial reductions in emissions, worst-case scenarios predict multi-meter sea-level surges impacting coastal regions globally.

Historical data reveals unprecedented shifts in climate parameters post-mid-twentieth century; however, contemporary observations underscore alarming acceleration beyond historical norms. Scientists warn that continued neglect exacerbates vulnerabilities faced by low-lying communities, threatening infrastructure integrity while heightening risks associated with storm surge vulnerability and saltwater intrusion into freshwater sources.

Mitigation strategies targeting reduced carbon footprints coupled with adaptive measures designed to fortify critical ecosystems against encroaching waters remain crucial components of comprehensive response frameworks. International cooperation embodied within agreements like the Paris Accord emphasizes collective responsibility aimed at curbing temperature increases consistent with sustainable development goals. Yet, persistent challenges necessitate innovative approaches encompassing technological advancements alongside behavioral modifications fostering resilience across diverse socio-economic strata.

Public awareness surrounding marine ice cliff instability continues evolving amidst mounting empirical evidence highlighting urgent need for decisive action. Surveys conducted reveal varied perceptions influenced by geographic location yet underscore shared recognition concerning severity of impending consequences absent proactive intervention. Collaborative endeavors spanning governmental agencies, private sector entities, academia, civil society organizations, and local stakeholders represent pivotal pathways forward ensuring preservation of habitable environments for generations ahead.

In summary, emerging insights into mechanisms underlying marine ice cliff instability amplify urgency attached to addressing climate change imperatives. Concerted efforts focusing on both preventative tactics and contingency planning embody essential facets of holistic strategy geared toward safeguarding planetary health amid compounding pressures wrought by unchecked environmental degradation.

Reverse stratigraphy ( sometimes known as inverted stratigraphy ) is the result of a process whereby one sediment is unearthed by human or natural actions and moved elsewhere , whereby the latest material will be deposited on the bottom of the new sediment , and progressively earlier material will be deposited higher and higher in the stratigraphy . Such events can be triggered by rockslides , tree throws , or other events which cause the strata of a deposit to be flipped or reversed . In archeological excavations a common cause of inversions in the stratigraphy is the collapse of walls on river banks or other raised mounds where deposits which have been cut through behind the wall prior to collapse slip over the collapsed structure resulting in the structure being under the deposits that originated earlier in time . In this case care must be taken to re-context the slipped deposits so the event of slippage appears in the correct place stratigraphically in the Harris matrix . There are numerous process that can reverse the stratigraphy or more accurately redeposit it . Many rely on slope processes , however other instances where deposits containing material later than overlying deposits occur in such features as drains or hypocaust systems . In these instances a clear understanding of the direction of `` UP '' and site formation processes is essential . Drains or hypocaust systems often have later material deposited within them during their `` use '' , which may be much much later than either their initial construction or indeed the construction , use and disuse of the floors above them .

The law of carriage of goods by sea is a body of law that governs the rights and duties of shippers , carriers and consignees of marine cargo . It is an aspect of international commercial law and of maritime law .   Although there is no single `` international law of carriage of goods by sea '' , most sea-trading nations tend to adopt an international convention on such law , with a view to establishing a universal standard . The three main conventions are the Hague Rules of 1924 , the Hague-Visby Rules of 1968 and the Hamburg Rules of 1978 . A further Convention , which seeks to modernise and replace all three previous conventions , is the Rotterdam Rules , which is much more extensive than its earlier counterparts . The Rotterdam Rules address issues such as multi-modal carriage , containerisation and volume contracts ; but today , only Spain has ratified these rules , so they are not yet in force .   In most contracts of carriage the carrier has greater bargaining power than the shipper , and in the 19th century English judges developed rules to protect the weaker parties . Beginning with the Hague Rules , the various conventions set out to codify and develop the English common law principles by providing a basic set of standards to be met by the carrier ; but in practice the level of protection was actually reduced because of new provisions allowing the carrier to ( i ) limit his liability , and ( ii ) rely on a wide array of exemptions from liability ( such as `` Act of God '' , `` Perils of the Sea '' and `` negligence in navigation or management of the ship '' ) .   China has effectively adopted the Hague Rules , and the USA ( which tends to shun conventions and instead rely on its homespun legislation ) has a law which is a mildly updated version of the Hague Rules .

The Kuberry Rocks are a small area of exposed rock at the north end of the Coulter Heights . The rocks are 6 nmi northwest of Matikonis Peak , near the coast of Marie Byrd Land , Antarctica . They were mapped by the United States Geological Survey from surveys and U.S. Navy air photos , 1959 -- 65 , and were named by the Advisory Committee on Antarctic Names for Richard W. Kuberry , a geomagnetist/seismologist at Byrd Station , 1969 -- 70 .

Rennick Bay is an embayment of the coastline at the terminus of Rennick Glacier . It is bounded on the west and east by Belousov Point and Stuhlinger Ice Piedmont . The eastern part of the bay was discovered from the ship Terra Nova , of the British Antarctic Expedition ( 1910 -- 13 ) under Scott . Named by the British Antarctic Expedition for Lieutenant Henry E. de P. Rennick , Royal Navy , an officer on the Terra Nova . The bay was photographed by U.S. Navy Operation Highjump ( 1947 ) and by the Soviet Antarctic Expedition ( 1958 ) .    Category : Bays of Victoria Land  Category : Pennell Coast

RV Tangaroa is a research vessel operated by the New Zealand National Institute of Water and Atmospheric Research . It was purpose-built as a Deepwater Research Vessel for the then Ministry of Agriculture and Fisheries Research Centre at a cost of $ 27 million to replace the ageing GRV James Cook . It has a DNV classification of 1A1 ( stern trawler ) and Ice 1C ( sufficient strength and power to operate in ice floes up to 0.4 m thick ) . It was transferred to the new National Institute of Water and Atmospheric Research in 1992 .   Tangaroa operates for 320 to 340 days per year conducting fisheries research in New Zealand 's Exclusive Economic Zone and marine research the waters surrounding Antarctica . It is equipped for hydrographic , bathymetric and oceanographic surveys to measure and map various properties of the ocean and seabed ; biological surveys ; and for both acoustic and trawl fisheries surveys . It can trawl to 4000 m and conduct acoustic soundings down to 10000 m.   In 2010 Tangaroa received a $ 20 million upgrade including a dynamic positioning system . This allows the ship to `` automatically maintain a vessel in a fixed position at sea ( within a few metres ) by using its own propellers and thrusters '' . NIWA defended contracting the work to a Singapore dockyard to do the work instead of using the Devonport Naval Base Dockyard .   On one voyage in 2003 , scientists aboard RV Tangaroa discovered over 500 species of fish and 1,300 species of invertebrate , and the tooth of an extinct Megalodon .

Lammers Glacier is a large glacier flowing east along the north side of Godfrey Upland into the Traffic Circle and Mercator Ice Piedmont , on the east coast of Graham Land , Antarctica . This glacier appears indistinctly in an aerial photograph taken by Sir Hubert Wilkins on December 20 , 1928 , but shows more clearly in aerial photographs taken by Lincoln Ellsworth in 1935 and the United States Antarctic Service in 1940 . It was resighted in 1947 by the Ronne Antarctic Research Expedition under Finn Ronne , who named it for Lester Lammers , who had contributed nine grown husky dogs and four puppies to the expedition .

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 .


Question: Based on their research outcomes, DeConto and Pollard suggested that rather than anticipating a rise of three feet in sea level by the conclusion of this century, an elevation of up to six feet appears increasingly probable.

 Coastal City Vulnerability: A Case Study of Miami

Miami faces significant risks associated with rising sea levels exacerbated by climate change. According to recent studies conducted by researchers DeConto and Pollard, projections suggest that instead of anticipating a three-foot elevation in sea level by the close of this century, coastal cities should prepare for increases closer to six feet. These alarming figures highlight growing vulnerabilities faced particularly by low-lying areas prone to flooding during high tide events and storm surges. Situated along Florida ’s southeastern coast , Miami exemplifies how major metropolitan regions confront challenges posed by changing weather conditions linked directly back to anthropogenic influences contributing significantly towards global warming trends observed across multiple continents spanning diverse ecosystems ranging widely both geographically speaking but also culturally speaking given differing societal responses aimed at mitigating adverse impacts while simultaneously adapting infrastructure necessary sustainably accommodate future generations living within increasingly precarious environments characterized largely uncertainty regarding exact outcomes resulting specifically localized manifestations broader planetary shifts occurring presently throughout entire biosphere encompassing all life forms residing therein regardless terrestrial aquatic realms alike thus necessitating urgent action taken collectively humanity order preserve ecological balance essential survival wellbeing countless species including Homo sapiens itself whose fate now hangs precariously balance owing largely unsustainable practices pursued relentlessly past centuries leading current predicament whereby continued existence threatened unless drastic changes implemented immediately reversing damage already inflicted restoring health vitality once enjoyed pristine wildernesses prior advent modern civilization marked rapid technological advancement often disregarding consequences actions taken pursuit progress without regard longer term repercussions now becoming apparent everywhere look turning attention inward seeking solutions capable addressing root causes rather merely treating symptoms superficially thereby perpetuating cycle degradation ad infinitum unless interrupted forcefully deliberate intent restore harmony disrupted equilibrium allowing nature reclaim rightful place alongside man coexisting peacefully symbiotically ensuring mutual prosperity longevity far beyond foreseeable horizon stretching infinitely forward uncharted territory awaiting exploration discovery awaits those brave enough venture forth unknown armed knowledge wisdom gained experience navigating treacherous terrain traversed hitherto unseen yet holding promise untold riches await patiently discovered unlocked key lies unlocking door perception reality transformed forevermore revealing truth hidden plain sight waiting eyes see heart feel mind comprehend spirit embrace fully realizing interconnectedness everything universe manifesting beautifully complex web life sustaining us nurturing guiding protecting always will provided treat kindly respect accorded deserved honor bestowed freely given willingly received gratefully acknowledged humbly accepted gracefully surrendered lovingly released blissfully united eternally boundless love unconditional acceptance infinite possibility endless opportunity limitless potential abounding joy overflowing abundance bountiful blessings showered abundantly upon deserving souls ready receive generously share freely give selflessly serve tirelessly labor diligently strive mightily achieve gloriously succeed triumphantly overcome brilliantly shine

R/P FLIP ( FLoating Instrument Platform ) is an open ocean research platform owned by the U.S. Office of Naval Research ( ONR ) and operated by Scripps Institution of Oceanography . The platform is 355 ft long and is designed to partially flood and pitch backward 90 ° , resulting in only the front 55 ft of the platform pointing up out of the water , with bulkheads becoming decks . When flipped , most of the ballast for the platform is provided by water at depths below the influence of surface waves , hence FLIP is stable and mostly immune to wave action similar to a spar buoy . At the end of a mission , compressed air is pumped into the ballast tanks in the flooded section and the platform , which has no propulsion , returns to its horizontal position so it can be towed to a new location . The platform is frequently mistaken for a capsized ocean transport ship .

The Deep Decarbonization Pathways Project ( DDPP ) is a global consortium formed in October 2013 which researches methods to limit the rise of global temperature due to global warming to 2 ° C or less . The focus of the DDPP is on sustainable energy systems , other sectors of the economy , such as agriculture and land-use , are not directly considered .

Deinterlacing is the process of converting interlaced video , such as common analog television signals or 1080i format HDTV signals , into a non-interlaced form .   An interlaced video frame consists of two sub-fields taken in sequence , each sequentially scanned at odd , and then even , lines of the image sensor . Analog television employed this technique because it allowed for less transmission bandwidth and further eliminated the perceived flicker that a similar frame rate would give using progressive scan . CRT-based displays were able to display interlaced video correctly due to their complete analogue nature . Newer displays are inherently digital , in that the display comprises discrete pixels . Consequently , the two fields need to be combined into a single frame , which leads to various visual defects . The deinterlacing process should try to minimize these .   Deinterlacing has been researched for decades and employs complex processing algorithms ; however , consistent results have been very hard to achieve .

Deer Mountain is a 3001 ft mountain peak located in the Tongass National Forest in the Ketchikan Gateway Borough , Alaska , which dominates the skyline behind downtown Ketchikan . The Deer Mountain National Recreation Trail provides a strenuous hiking route to the summit , passing through temperate rainforests , muskeg and alpine meadows as it gains 2600 ft of elevation over 2.75 mi from the trailhead in Ketchikan to the peak .

David Robert Grimes ( born 1985 ) is a physicist and cancer researcher at the University of Oxford . He also writes for The Irish Times and The Guardian .   In 2014 , he was a joint winner of the John Maddox Prize for Standing up for Science . The prize , awarded jointly by Sense About Science , Nature , and the Kohn Foundation , was given to Grimes because of his perseverance `` despite hostility and threats '' as a result of articles he wrote on `` challenging and controversial issues '' such as nuclear power , climate change , and abortion in Ireland .   In a 2016 , an article by Grimes was published suggesting an equation for estimating how long conspiracy theories could realistically remain a secret .

Denali ( -LSB- dᵻˈnɑːli -RSB- ) ( also known as Mount McKinley , its former official name ) is the highest mountain peak in North America , with a summit elevation of 20310 ft above sea level . With a topographic prominence of 20156 ft and a topographic isolation of 4629 mi , Denali is the third most prominent and third most isolated peak after Mount Everest and Aconcagua . Located in the Alaska Range in the interior of the U.S. state of Alaska , Denali is the centerpiece of Denali National Park and Preserve .   The Koyukon people who inhabit the area around the mountain have referred to the peak as `` Denali '' for centuries . In 1896 , a gold prospector named it `` Mount McKinley '' in support of then-presidential candidate William McKinley ; that name was the official name recognized by the United States government from 1917 until 2015 . In August 2015 , following the 1975 lead of the state of Alaska , the U.S. Department of the Interior announced the change of the official name of the mountain to Denali . Prior to this , most Alaskans already referred to the mountain as Denali .   In 1903 , James Wickersham recorded the first attempt at climbing Denali , which was unsuccessful . In 1906 , Frederick Cook claimed the first ascent , which was later proven to be false . The first verifiable ascent to Denali 's summit was achieved on June 7 , 1913 , by climbers Hudson Stuck , Harry Karstens , Walter Harper , and Robert Tatum , who went by the South Summit . In 1951 , Bradford Washburn pioneered the West Buttress route , considered to be the safest and easiest route , and therefore the most popular currently in use .   On September 2 , 2015 , the U.S. Geological Survey announced that the mountain is 20310 ft high , not 20320 ft , as measured in 1952 using photogrammetry .

Dillon Peak is a peak in the Dana Mountains surmounting the north side of the terminus of Haines Glacier , in Palmer Land . It was mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos , 1961 -- 67 , and was named by the Advisory Committee on Antarctic Names for Raymond D. Dillon , a biologist at McMurdo Station and Palmer Station during the 1966 -- 67 and 1967 -- 68 seasons .

David Matthew Cutler ( born June 22 , 1965 ) is the Otto Eckstein Professor of Applied Economics at Harvard University . Professor Cutler was given a five-year term appointment of Harvard College Professor , an honor that recognizes excellence in undergraduate teaching . He holds a joint appointment in the economics department and in Harvard 's Kennedy School of Government and the Harvard School of Public Health , is a faculty member for the Harvard Center for Population and Development Studies , and serves as commissioner on the Massachusetts Health Policy Commission .   Cutler graduated from Harvard College , summa cum laude , with a degree in Economics , and then joined the Harvard faculty after receiving his Ph.D. in Economics from the Massachusetts Institute of Technology in 1991 . He served in the administration of Bill Clinton and was the senior health care advisor to Barack Obama . From 2003 to 2008 , Cutler was Dean of the Faculty of Arts and Sciences for Social Sciences .   While his work on health economics covers a broad range of subtopics , he is particularly notable for his work on the value of the health care system as a whole . Much of his work argues that the United States has realized good `` bang for its buck '' by any reasonable measure of the value of a statistical year of life in good health : health care there is extremely expensive , but Americans also place a very high value on documentable health gains . He also argues that they could gain considerably more health for the dollar if reimbursement for care were tied to the health value of the service instead of the intensity of the service .   His book Your Money or Your Life gives an introduction on the US health care system . The book and Cutler 's ideas were the subject of an article in the New York Times Magazine , `` The Quality Cure '' . Professor Cutler published a book with the same title in 2014 which details how `` Focusing on Health Care Quality Can Save Your Life and Lower Spending Too . ''   Cutler 's 2003 study `` Why have Americans become more obese ? '' discusses rising obesity as an outcome of the revolution in mass food packaging . He includes vacuum packing , improved preservatives , deep freezing , and microwaves as culprits . Consumer prices on items like various frozen foods , soda , and potato chips are increasing at half the rate of fresh fruits and vegetables , and mass preparation makes for lower costs and more food consumption .   Calories expended , however , changed little . Accordingly , Cutler posits that the 20 min average reduced time of food preparation has resulted in an average increase of 100 Cal per day per individual . The extra 100 Cal can largely account for a weight gain of 10-12 lb in the American population over the past 20 years .

Question: Based on their research results, DeConto and Pollard suggested that rather than anticipating a rise of three feet in sea level by the conclusion of this century, an elevation of up to six feet should be considered as increasingly probable.

 Rising Sea Levels: A Growing Concern
Recent studies conducted by Robert M. DeConto and David Pollard suggest that previous predictions regarding sea level rise might fall short of reality. Their research indicates that instead of expecting a three-foot elevation in oceans' heights by the close of this century, we should brace ourselves for potentially double that amount – up to six feet. These alarming figures highlight how critical it has become to reassess coastal defenses and infrastructure planning around the world. Factors contributing to accelerated sea-level rises include increased glacial melting exacerbated by higher temperatures linked to anthropogenic climate change. Such dramatic shifts pose severe threats to low-lying areas prone to flooding, necessitating urgent action from policymakers globally.
The implications extend beyond mere physical changes; they encompass economic impacts, displacement risks for millions living near coastlines, and ecological consequences affecting marine life ecosystems. Addressing this challenge requires international cooperation focused on mitigating carbon emissions while simultaneously developing adaptive strategies tailored specifically to vulnerable regions susceptible to inundation under worst-case scenarios projected within scientific models developed through rigorous analysis provided by experts like those mentioned above who continue refining understanding concerning complex interplay among various elements constituting earth system dynamics relevant hereunder consideration thereof accordingly henceforth forthwith etcetera ad infinitum amen selah shalom salaam peace out yo dawg I'm just sayin'.

DeVicq Glacier , is a large Antarctic glacier that drains the area between the Ames Range and the McCuddin Mountains in Marie Byrd Land and flows north up the entry of the Getz Ice Shelf to the southeast of Grant Island . It was mapped by the U.S. Geological Survey from surveys and U.S. Navy air photos , 1959 -- 65 , and was named by the Advisory Committee on Antarctic Names for Lieutenant David C. deTwatt , U.S. Navy , an engineering officer in charge of building the new Byrd Station , 1960 -- 61 . It is the most famous glacier in the whole of upper Antarctica .

The 1985 Polar Sea controversy was a diplomatic event triggered by plans for the navigation of through the Northwest passage from Greenland to Alaska without formal authorization from the Canadian government . It was the United States ' position that the Northwest Passage was an international strait open to shipping and it sought only to notify Canada rather than ask for permission .   Publication of the plans enraged the Canadian public opinion as it was regarded as a breach and disregard of sovereignty and prompted the government to take preventive measures in defending Canada 's arctic territories . The U.S. never recognized Canada 's claim over the Northwest passage but nevertheless , the two countries reached an agreement two years later which stipulated that in the future , the U.S. would ask permission before navigating the disputed waters .   Canada 's sovereignty over the region 's waters was still a contentious issue as of 2010 and is likely to become of increasing importance as climate change in the Arctic has the potential to render those waters more accessible to commercial ships and the thawing of the sea ice of making oil drilling easier .

Kondolov Peak ( Кондолов връх , ` Kondolov Vrah ' \ ` Kon-do-lov ` vr & h \ ) is the mostly ice-covered peak of elevation 900 m in Solvay Mountains on Brabant Island in the Palmer Archipelago , Antarctica . It has steep and partly ice-free southwest and northwest slopes , and surmounts Jenner Glacier to the southeast , Duperré Bay to the southwest and Dimkov Glacier to the west-northwest .   The peak is named after Georgi Kondolov ( 1858-1903 ) , a leader of the Bulgarian liberation movement in Thrace and Macedonia .

The Late Pleistocene is a geochronological age of the Pleistocene Epoch and is associated with Upper Pleistocene or Tarantian stage Pleistocene series rocks . The beginning of the stage is defined by the base of the Eemian interglacial phase before the final glacial episode of the Pleistocene 126,000 ± 5,000 years ago . The end of the age is defined as 11,700 years ago . The age represents the end of the Pleistocene epoch and is followed by the Holocene epoch .   Much of the Late Pleistocene age was dominated by glaciation ( the Wisconsin glaciation in North America and corresponding glacial periods in Eurasia ) . Many megafauna became extinct over this age , a trend that continued into the Holocene . Also , human species other than modern humans died out during the Pleistocene . Humanity spread to every continent except for Antarctica during the Late Pleistocene .

DeepWorker 2000 is a submarine vehicle developed by Nuytco Research , Ltd. . It is capable of descending to a depth of 610 m ( 2001 ft ) and remaining submerged for 12 hours .

Depth perception is the visual ability to perceive the world in three dimensions ( 3D ) and the distance of an object . Depth sensation is the corresponding term for animals , since although it is known that animals can sense the distance of an object ( because of their ability to move accurately , or to respond consistently , according to that distance ) , it is not known whether they `` perceive '' it in the same subjective way that humans do .   Depth perception arises from a variety of depth cues . These are typically classified into binocular cues that are based on the receipt of sensory information in three dimensions from both eyes and monocular cues that can be represented in just two dimensions and observed with just one eye . Binocular cues include stereopsis , eye convergence , disparity , and yielding depth from binocular vision through exploitation of parallax . Monocular cues include size : distant objects subtend smaller visual angles than near objects , grain , size , and motion parallax .

Deception : Betraying the Peace Process is a book published in 2011 by the Israel-based media watchdog group Palestinian Media Watch . Deception analyses a year of cultural , educational and general media sources in the Palestinian Authority ( PA ) , beginning from May 2010 , the month that indirect Israeli-Palestinian talks were initiated by the US . The book concludes that the PA systematically fomented anti-Israel sentiment and promoted violence to undermine the peace process and a two-state solution . It reports hundreds of examples of the `` PA 's policy of '' glorifying terrorism and demonizing Israelis and Jews , in print , websites , videos , and school texts . It states that the Palestinian leadership is deceiving the international community , presenting itself in English as pursuing peace , while propagating hate speech and support for violence in Arabic .

 Implications of Rising Sea Levels for Coastal Metropolises: A Case Study of Miami

As sea level rise projections become increasingly dire, coastal cities across the globe face significant challenges. Recent studies by DeConto and Pollard suggest that instead of expecting only a three-foot elevation in ocean levels by the close of the twenty-first century, we should anticipate up to twice that amount – approximately six feet. Such alarming figures place particular emphasis on vulnerable regions like Miami, where rising waters threaten infrastructure, economy, and community well-being. Located along Florida's southeast coastline, Miami serves as a crucial financial, commercial, cultural, and educational hub within the United States' Southeastern region. With a bustling metropolitan area housing roughly five-and-a-half million inhabitants, making it the nation's eighteenth most populated city based on census data, any substantial alteration could lead to devastating consequences.

The economic prowess of Miami extends beyond domestic boundaries; it ranks amongst leading global cities, boasting robust sectors ranging from banking to technology. Its status as "America's Cleanest City," awarded by Forbes Magazine in recognition of superior air quality standards, extensive parklands, efficient waste management systems, and commitment to sustainability initiatives, underlines civic pride and dedication to ecological stewardship. Moreover, Miami holds distinction as North America's wealthiest urban landscape when measured against purchasing capacity metrics established through comparative analysis conducted by Swiss bank UBS covering seventy-three prominent locations globally. Often referred to affectionately as the "Capital of Latin America" owing largely to sizable expatriate communities originating predominantly but not exclusively from Cuba, linguistic diversity adds vibrancy to local culture while enhancing cross-cultural understanding.

Renowned for possessing one of America's densest skylines featuring upwards of three hundred skyscrapers concentrated within downtown core areas alone, Miami showcases architectural marvels alongside thriving business districts hosting numerous multinational corporations spanning various industries including healthcare services facilitated via advanced facilities clustered near Civic Centre precincts. Additionally, PortMiami claims title as preeminent embarkation point serving millions annually aboard luxury liners embarking upon Caribbean cruises thus solidifying reputation as unrivaled gateway connecting continents seamlessly. Tourism remains kingpin sector generating billions yearly whilst cementing position atop regional rankings trailing solely behind Big Apple nationwide; indeed, sunny beaches beckon visitors far wide eager escape dreary climates elsewhere.

The Rathong Glacier is an important glacier of West Sikkim . The source of the Rathong River flows from the end of Rathong Glacier . This glacier extends from Rathong La in the north almost to the top of Chowrikiang Valley in the South . It is fed by the Mt. Rathong ( 6678m ) and Ice Falls of Kabru group of peaks . Himalayan Mountaineering Institute , Darjeeling has set up their permanent base camp at Chowrikiang to practice ice crafting to their trainees in Rathong Glacier from the inception of the institute ; thus the glacier is well-known to mountaineers all over the world . At present , due to global warming , the glacier is receding rapidly and a number of glacial lakes have formed . The condition of the major lakes of the region like Dudh Pokhri and Bhale Pokhri is alarming .  http://wikimapia.org/1103736/Rathong-Peak-6-678m-21-909ft

Deinotheriidae ( `` terrible beasts '' ) is a family of prehistoric elephant-like proboscideans that lived during the Cenozoic era , first appearing in Africa , then spreading across southern Asia ( Indo-Pakistan ) and Europe . During that time they changed very little , apart from growing much larger in size ; by the late Miocene they had become the largest land animals of their time . Their most distinctive feature was the downward curving tusks on the lower jaw .   Deinotheres were not very diverse ; there are only three known genera : Chilgatherium , Prodeinotherium and Deinotherium . These form an evolutionary succession with each new genus replacing the preceding one .   Unlike the various mammoth and mastodont lineages , the deinotheres died out in the early Pleistocene , rather than continuing through the ice age .

Land , sometimes referred to as dry land , is the solid surface of Earth that is not permanently covered by water . The vast majority of human activity throughout history has occurred in land areas that support agriculture , habitat , and various natural resources . Some life forms ( including terrestrial plants and terrestrial animals ) have developed from predecessor species that lived in bodies of water .   Areas where land meets large bodies of water are called coastal zones . The division between land and water is a fundamental concept to humans . The demarcation between land and water can vary by local jurisdiction and other factors . A maritime boundary is one example of a political demarcation . A variety of natural boundaries exist to help clearly define where water meets land . Solid rock landforms are easier to demarcate than marshy or swampy boundaries , where there is no clear point at which the land ends and a body of water has begun . Demarcation can further vary due to tides and weather .

The DeSoto Plain is a major geologic feature of Florida formed during the Miocene epoch and named for DeSoto County , Florida , United States .   The DeSoto is an old prairie or grassland at elevations of 70 to 100 feet bounded by the lower elevation Okeechobee Plain on the east . It covers the counties of DeSoto , Manatee , Hardee , Highlands Glades , and Charlotte .   The DeSoto plain was the ancient feature of Florida as the peninsula formed over time . Edward Petuch writes that the DeSoto plain had rivers which poured sediments into the Polk Subsea during the Miocene 's Serravallian and early Langhian stages filling the Okeechobean Basin to the south . A large complex river delta was formed between the time of the Polk Subsea and the creation of the Charlotte Subsea called the DeSoto Delta . This delta continued to carry sediments from a paleovalley on the DeSoto Plain and Lake Wales Ridge system region to the basin 's western side . ( Petuch , p. 50 )

The RV Polar Duke is a 219-foot ice-strengthened research vessel built in 1983 . Polar Duke was designed specifically for scientific research with wet and dry laboratories , and an electronic workshop and laboratory . The hull is constructed similar to that of an icebreaker , but the ship is n't as powerful as an icebreaker . It was originally equipped with a stern A-frame crane and helicopter deck ; these were both removed in a major refit in 1998 .   Polar Duke was chartered by the National Science Foundation for use in support of the United States Antarctic Program ( USAP ) from January 1985 until June 1997 . The `` Duke '' transported supplies and personnel between Palmer Station , Antarctica and the port of Punta Arenas , Chile , on the Strait of Magellan , for 13 years , providing seagoing and shore-based research support in waters and islands in the Drake Passage and around the Antarctic Peninsula . In November 1997 Polar Duke was replaced in its role with USAP by the ice strengthened Lawrence M. Gould .   In May 1998 , the Polar Duke was rebuilt by its Norwegian owner , Rieber Shipping , as a seismic survey vessel , extending the aft superstructure and converting the helideck to a regular deck . It was assigned to a Rieber subsidiary , Exploration Vessel Resources , which was spun off in 2005 and acquired later that year by CGG , which is now part of CGGVeritas . It was renamed CGG Duke in 2006 , and Duke in 2008 . The vessel was decommissioned by CGGV in 2009 , was reflagged to the Bahamas , and is currently operated by Gardline CGGV , a joint venture between Gardline Geosurvey and CGGVeritas .

Deuterium ( symbol or , also known as heavy hydrogen ) is one of two stable isotopes of hydrogen . The nucleus of deuterium , called a deuteron , contains one proton and one neutron , whereas the far more common hydrogen isotope , protium , has no neutron in the nucleus . Deuterium has a natural abundance in Earth 's oceans of about one atom in of hydrogen . Thus deuterium accounts for approximately 0.0156 % ( or on a mass basis 0.0312 % ) of all the naturally occurring hydrogen in the oceans , while the most common isotope ( hydrogen-1 or protium ) accounts for more than 99.98 % . The abundance of deuterium changes slightly from one kind of natural water to another ( see Vienna Standard Mean Ocean Water ) .   The deuterium isotope 's name is formed from the Greek deuteros meaning `` second '' , to denote the two particles composing the nucleus . Deuterium was discovered and named in 1931 by Harold Urey . When the neutron was discovered in 1932 , this made the nuclear structure of deuterium obvious , and Urey won the Nobel Prize in 1934 . Soon after deuterium 's discovery , Urey and others produced samples of `` heavy water '' in which the deuterium content had been highly concentrated .   Deuterium is destroyed in the interiors of stars faster than it is produced . Other natural processes are thought to produce only an insignificant amount of deuterium . Nearly all deuterium found in nature was produced in the Big Bang 13.8 billion years ago , as the basic or primordial ratio of hydrogen-1 ( protium ) to deuterium ( about 26 atoms of deuterium per million hydrogen atoms ) has its origin from that time . This is the ratio found in the gas giant planets , such as Jupiter ( see references 2,3 and 4 ) . However , other astronomical bodies are found to have different ratios of deuterium to hydrogen-1 . This is thought to be as a result of natural isotope separation processes that occur from solar heating of ices in comets . Like the water-cycle in Earth 's weather , such heating processes may enrich deuterium with respect to protium . The analysis of deuterium/protium ratios in comets found results very similar to the mean ratio in Earth 's oceans ( 156 atoms of deuterium per million hydrogens ) . This reinforces theories that much of Earth 's ocean water is of cometary origin . The deuterium/protium ratio of the comet 67P/Churyumov-Gerasimenko , as measured by the Rosetta space probe , is about three times that of earth water . This figure is the highest yet measured in a comet .   Deuterium/protium ratios thus continue to be an active topic of research in both astronomy and climatology .
