These models currently predict that as a result of today’s global climate change, Antarctica will warm twice as much as the rest of the planet, though it won’t reach its peak for a couple of hundred years. While the most likely climate change scenario, given business-as-usual greenhouse gas emissions, is a global average increase of 3 degrees Celsius (5 degrees Fahrenheit) by 2100, the Antarctic is predicted to warm eventually by around 6 degrees Celsius (10 degrees Fahrenheit).

About Antarctica: Ice Ages & Global Warming
Ice Ages & Global Warming. Through out its history, the Earth has continuously warmed and cooled. The most recent ice age began 20-30 million years ago. At the time, Antarctica was still undergoing radical changes. It had recently separated from Gondwanaland and began its slow drift southward. ...

Global Warming. Antarctica is one of the world’s greatest wildernesses. ... In Antarctica, global warming has caused ice shelves to disintegrate, collapse or break up, ocean temperatures to increase and ice thickness to decrease. In the Antarctic Peninsula region, an increase in annual temperature has caused the spread of the two owering plants in the last few decades.
Global warming and the stability of
Along with ideas, discussed below, that marine ice sheets may be inherently unstable, Mercer’s ndings led to concern that global warming might cause WAIS to collapse. In contrast, other major ice sheets either are largely grounded above sea level and subject to very gradual ablation from moderate warming (Greenland) or have no clear history of major, rapid, ice mass changes in the recent geological past (East Antarctica).

Greenhouse warming, the Arctic, and Antarctica
It seems likely that global warming will have different effects near the North and South Poles. The Arctic (north of 60° N) is warmed by about 6.5K in the GFDL GCM, whereas the equivalent Antarctic region warms by only 3.5K. This is because more warmth in Antarctica would allow the air to hold more water vapour, leading to increased precipitation and so a thickening of the snow cover.

Don’t attribute a hot day (or reduced Antarctic ice) to global warming; the effect is more subtle. But it is real, and it is very likely that at least some of the warming of the past 50 years has been caused by humans, primarily from our burning of fossil fuels. ... The melting of Antarctica appears to contradict global warming, but uncertainties are so large, that it is best to base conclusions solely on the temperature record.

Global Warming
Global Warming is being caused by the “greenhouse effect.” Gases emitted by cars, factories, home heating, etc. don’t allow heat to escape the Earth’s atmosphere. They allow light to go through but not heat (like a greenhouse). Global warming affects all aspects of life. It has been melting snow and ice in the Arctic regions, which has caused a need for lifestyle changes for animals such as polar bears. Rainfall patterns have changed in the tropics and subtropics.

The problem of global warming
The issue of global warming can seem overwhelming and complex, but the scientific explanation for the phenomenon is relatively simple. Earth has a built-in system for temperature control made up of gasses in the planet's atmosphere. When the sun's rays strike and warm the Earth, these gasses operate like a blanket, trapping some of the sun's warmth inside and allowing some of the heat to be released into space.

One such issue is global warming. The Earth has seen many changes in temperature within its life time but none so dramatic as what has been observed in today’s day in age. There is much scientic evidence to conrm these results. It is predicted that the Earth will go through major economical, social, and environmental changes if the problem of global warming, due to the greenhouse eect, is not addressed soon. There has been some recent movement how to solve these problems but progress is slow.
An Overview of Climate Change/ Global Warming: How It Is...
Global warming has caused the rise in global temperatures, the risk of huge natural disasters, the spread of diseases, and the deaths of about 150,000 people annually according to the World Health Organization. The terms climate change and global warming have been used as interchangeable terms, but there is a difference in the two meanings. ‘Climate change’ helps show that there are other changes besides rising temperatures.

Antarctic fungal diversity blooms as continent warms
Dr Dennis said surface air temperatures in the maritime Antarctic had risen by up to 2.8 °C over the past 50 years, at rates several times that of the global average. “Our research has demonstrated that, in this rapidly warming part of Antarctica, temperature is the main factor that determines soil fungal diversity,” he said. The study found said that the majority of fungi were microscopic – and the average person might not find them as charismatic as animals – but they had important roles to play in soils as plant decomposers and as...

The atmospheric CO2 level has been up to 10 times higher in the past. Why weren't there catastrophic consequences then?

Nakada & Lambeck (1988) argue that the temporal pattern of deglaciation may explain the pattern of global sea level changes resulting from Antarctica meltwater input. Specically, the WAIS and Antarctic Peninsula Ice Sheet are key sectors for watching the meltwater input into the ocean, because most of the glaciers on both areas are grounded below sea level and, thus, most susceptible to global warming and consequent sea level rising.

How can global warming affect sea levels? An average increase of 3oC in atmospheric temperature would cause an increase in global sea levels of 0.2 to 1.5 meters.
