A new NASA study revealed that the oldest and thickest Arctic sea ice is disappearing at a faster rate than the younger and thinner ice at the edges of the Arctic Ocean’s floating ice cap. The thicker ice, known as multi-year ice, survives through the cyclical summer melt season, when young ice that has formed […] … learn more→

NASA finds thickest parts of Arctic Ice cap melting faster
As emissions rise, we may be heading for an ice-free planet
Last December’s meeting of the American Geophysical Union featured three of the world’s leading climate scientists: James Hansen (NASA’s chief climate scientist), Elco Rohling (National Oceanography Centre, Southampton) and Ken Caldeira (Stanford School of Earth Science). But it was Hansen who attracted the most attention when he stated: “If you doubled CO₂, which practically all […] … learn more→
Loss of Arctic sea ice: don’t let the GFC distract you, climate change is happening
A few weeks ago, NASA announced that the area of Arctic ice is now almost as low as it was in 2007, its historic minimum. The extent of ice has reduced to 4.33 million km² compared to the mean (1979 to 2000) of 7.04 million km². Simultaneously, three navigation routes have opened across the Arctic […] … learn more→
