Antarctica Is The Third Largest Continent On The World Map

The global mean surface temperature is projected to increase by around 0.3 to 4.8 degrees Celsius above the pre-industrial values by the end of the 21th century. Therefore, if we continue to not check the anthropogenic emissions, the increase may be around 8 to 10 degrees Celsius, which is incredibly damaging to various ecosystems internationally. It is difficult to determine the possible aftereffects of the ice sheets melting because the equilibrium-response timescales of them is longer than both the atmosphere and ocean. The ice-sheet/ice-shelf model shows that if the atmospheric warming increases 1.5 to 2 degrees Celsius above the present temperatures, the Antarctic ice shelves will collapse and trigger a centennial scale response –a never-ending

Antarctica is the coldest, driest, and most inhospitable continent on Earth. Yet it is yields some 90 percent of the Earth most precious natural resource: water. But behind this pristine exterior, Antarctica is fighting a losing battle. New data suggests that the continent as a whole is warming at an alarming rate. According to recent studies gathered from Nature Magazine, the western half of the continent is warming five times faster than any other place

Earth has experienced many episodes of dramatic climate changes with different periods in earth history. There have been periods during which the entire planet has been covered in ice and at another time it has been scorchingly hot and dry. In this regards, earth has experienced at least three major periods of long- term frigid climate and ice ages interspersed with periods of warm climate. The last glacial period which current glaciers are the result of it, occurring during the last years of Pleistocene, from approximately 110,000 to 10,000 years age (Clayton, 1997). Indeed, glaciers present sensitive indicators of climate change and global warming and by estimating and monitoring the dynamic evolution of these ice masses, several

Ice ages are well documented in Earth’s history, and they are proven to be relatively frequent. But what if that ice age persisted over not just regions near the poles, but around the equator as well? The term “snowball Earth” refers to a condition where Earth is completely covered by ice. Evidence indicates that snowball Earth may have been around in the Neoproterozoic. In fact, evidence points to the conclusion that these conditions happened three separate times in the Neoproterozoic. A snowball Earth condition is hard to prove, but this theory may explain several different phenomena. However, it is not accepted by all, there is evidence against a snowball Earth as well. Some believe that a snowball Earth would not have been possible in past climate conditions while there are views that defend the idea of more of a ‘slushball’ Earth rather than a planet entirely frozen on the surface.

Collaborating on an international level remains important for conducting ice patch research due to the rapid melting of alpine ice and decay of valuable artifacts. The work conducted for this thesis included cooperation from Parks Canada. Ice patch research was conducted not only on the U.S. side of the international border, but also on the Canadian side of Chilkoot Pass. Parks Canada allowed me and KLGO archaeologists to use the Canadian warden cabin at the summit of Chilkoot Pass as a basecamp for the ice patch study (Figure 1.4). Working between two sovereign countries emphasizes the matter of climate change as a global issue and the importance in maintaining international relations. Maintaining international relations benefits the scientific community on a global scale and provides significant research opportunities.

Has anyone lived a life without misfortune? Doubtable; even the person with what could be described as the ideal life deals with some form of adversity. The novel, Speak, and the short story, The Third and Final Continent, both use plot as a way to convey themes of hardship. Moreover, these texts both use symbolism in order to develop their themes as well. The Art of Resilience and Speak utilize characterization as a method of developing their respective themes. Speak, The Third and Final Continent, and The Art of Resilience each deal with the theme that all people must learn to cope with adverse situations.

Millions of miles of ice and an unfriendly environment make Antarctica an exciting place to study. It is very unique, and doesn’t have the same properties as the other continents do. It is much colder than the rest of the world. For example, the average temperature in Antarctica during the summer months is about 32 degrees fahrenheit! The coldest temperature ever recorded anywhere was in Antarctica, at the Russian Vostok station. It was -129.3 degrees fahrenheit!! In addition, the continent contains 90% of the world’s ice, and it is bigger than the United States. “It is the coldest, windiest, and driest continent in the world”. (Redd) In fact, the average precipitation there is only 2 inches every year. Believe it or not, Antarctica is classified as a desert, because it is so dry, and has such a minimal amount of moisture. “More rain falls in the Sahara Desert”. (Redd) Even though there is very little snow, Antarctica still has massive blizzards. The heavy winds pick up snow from the ground and blow it around. Winds in Antarctica have been known to reach 200 miles

The convention applies to the area south of sixty degrees. Antarctica is an exceptional, remote continent surrounded by a wide, cold and stormy ocean. To some Antarctica is simply a cold, distant uninviting and dangerous place with little to offer the world. Antarctica is the last and largest unspoiled wilderness area on Earth. It is a reminder of what the planet was like before the influence of man. Its unspoiled beauty has inspired people, since first glimpse, to explore and discover the vast desert like continent. Antarctic has stretches of the most pristine oceans on earth with an enormous variety and quantity of marine life, much of which is only found in Antarctica. Antarctica is a continent for science, as it is so unspoiled it acts as a laboratory for the rest of the world where changes can be measured in isolation from the effects of

The last glacial period has encountered numerous large-magnitude, rapid climate change events; characterising the period between 10ka and 50ka (Steig, 1999). During this period was the Last Glacial Maximum (LGM), which occurred approximately 21ka, a glacial period defined by changes in greenhouse gases, sea level and ice sheets (Otto-Bliesner et al., 2006). In comparison the mid-Holocene occurred approximately 6000 years ago, during the current interglacial. The Holocene period is regarded as relatively muted in terms of ‘signals’ of climate change, with changes primarily associated with changes in seasonal solar radiance (Otto-Bliesner et al., 2006; Steig, 1999).

Antarctica is Earth’s southernmost continent.Antarctica is the coldest of Earth's continents and is a frozen desert with little precipitation. There are countless number of animals(including penguins, blue whales, orcas, colossal squids and fur seals), fungi(such as Cryomyces antarcticus, and Cryomyces minteri), plants and other organisms. Nonetheless, the biodiversity is consistently changing over past century and strongly affected by the climate change in recent years.

The West Antarctic Peninsula is one of the fastest warming areas on Earth, with only some areas of the Arctic Circle experiencing faster rising temperatures. However, since Antarctica is a big place, climate change is not having a uniform impact, with some areas experiencing increases in sea ice extent. Yet in others, sea ice is decreasing, with measurable impacts on wildlife. ASOC believes that understanding climate change impacts on Antarctica is a matter of critical importance for the world and for the continent

Antarctica is the Earth’s southernmost continent, it is responsible for the frigid temperatures that have a cooling effect on our atmosphere. The centrally located tropical waters derive their source of heat from the sun; together these two bodies of water combine to regulate our ecosystem. Quite alarming, this delicate temperature balance is at stake due to interference from humankind

Climate record amplifying deep into the Earth past has been Assembled, and keeps on being developed, in view of geographical proof from borehole temperature profiles, centers expelled from profound aggregations of ice, botanical and faunal records, chilly and periglacial

Antarctica was not always the frozen, dry continent we know it to be presently. Two hundred million years ago, it was the center of a “supercontinent” called Gondwana that included parts of South America, Africa, India, and Australia.

After watching the NOVA documentary about Antarctica Secrets, one is amazed at the work done by Scientists, Geologist and Engineers applying innovative drilling technology to study ice sheets and ocean core sediments that can reveal the climate history of Antarctica.
