Hardly a day goes by, it seems, without fresh evidence of climate change. New reports—from Greenland to Antarctica—show rising temperatures at both poles and changing conditions in what were once stable, icebound areas. A sampling:
• Data from NASA, European, and Canadian satellites show a continuing impact from the collapse of the Larsen B ice shelf in early 2002. Nearby glaciers along the Antarctic Peninsula are now flowing into the open ocean three to eight times faster than when they were buttressed by the ice shelf, contributing significantly to rising sea levels. Additionally, NASA satellites found that some glaciers in the area have thinned by up to 125 feet.
• Populations of krill have declined by 80 percent in the Southern Ocean in the last 30 years. An international team of oceanographers attributed the drop to a loss of winter sea ice that supports the algae on which young krill ...
