Humans To Artic & Antarctic

The polar bears and penguins (respectively) are already looking for places to hide as man increases his presence on the two least habitable places on earth. The goal, or main goal of, these arctic and antarctic research expeditions, is to study the earth’s warming.


If All Of Greenland’s Ice Melted The Ocean’s Would Rise By 20 Feet

[T]he most pressing questions being pursued relate to warming caused by the atmospheric buildup of heat-trapping gases like carbon dioxide. Experts involved with the polar year say the Earth’s coldest places are likely to be especially affected.

“The poles are going to lead the way in climate change,” said Ted Scambos, a researcher at the National Snow and Ice Data Center in Boulder, Colo. “To know what we’re in for in the next 10 years, in sea level or in climate, we need to look at the poles now. They are the amplifiers of the small warming that greenhouse gases cause.”

Particularly urgent, many experts said, is the need to improve understanding of the complicated forces that might cause warming ice sheets in Greenland and parts of Antarctica to flow more quickly into the sea.

Greenland’s vast ice cap is twice the size of California, and it holds as much water as the Gulf of Mexico.
