Hydrosphere: Vast expanses of Arctic ice melt in summer heat



Standing on the shore of the Arctic ocean 1500 miles north of Seattle in Canada, the ice level has receded twice as far out as it was 40 years ago. It used to be 40 miles out from land, now the ice is 80 miles off shore and still shrinking.


"Global average temperatures rose 1 degree over the past century but twice as much over the Arctic as elsewhere, most likely attributable to manmade greenhouse gases researchers say.

The United Nations Work on Global Climate Change has the UN Secretary General Ban-Ki Moon in the Arctic Rim to see for himself the melting ice. He hopes to use this information to spur a world wide accord this December in the Copenhagen, Denmark to get a petition signed by major countries that would commit to limiting greenhouse gas emissions.
