One might assume that anything that might reflect sunlight back into space, like bright aircraft contrails, would be good for decreasing the effects of global warming, but a new study predicts that the atmospheric heat trapped by the water vapor in the ‘trails will triple by the middle of theread more

Scientists have been concerned for many years that the collapse of a continental glacier on Greenland or the Antarctic could result in a rapid and dangerous rise in sea levels, and now the surprising condition of an Antarctic glacier has seriously increased that concern.

A group of international scientists recently led a two month-long expedition to one of Antarctica’s most remote regions to measure the rate of ice melt under the 50km-long Pine Island Glacier, and the results have concerned glaciologists worldwide. The glacier, which thins out towards the Amundsen Sea at a rate of about 2.5 miles (4 kilometers) each year, has been carefully monitored by scientists because it has been identified as one of the most rapidly melting ice masses in the world.
