Topic: global warming news - Scientists Confirm Global Warming at North and South Poles - Voice of America
Jumbled ice blocks litter the surface of the floating ice pack at the North Pole While studies are reasonably clear on the role of carbon emissions by humans in causing global warming in the Arctic, less is know about the causes of warming in Antarctica because of its remoteness. In a study in this week's issue of Nature Geoscience , an international team of scientists reports on the results of a new model they say proves the human footprint in global warming
in the Antarctic. The model incorporates 100 years worth of temperature data from the Arctic and about 50 years of recorded temperatures from stations in Antarctica. The temperatures in the Antarctic were gathered along the coastal areas, according to scientists, because it is too difficult to get to the continent's interior. When the temperature data from both continents were plugged into the model, scientists say it clearly showed the human effects of global warming in the South Pole.
