NASA: Vast Antarctic ice shelf a few years from disintegration

NASA has found that the last section of Antarctica’s Larsen B Ice Shelf is likely to disintegrate before the end of the decade. Transcript: We know that this ice shelf existed for at least 11 to 12 thousand years. In 2002, two-thirds of it collapsed in less than six weeks. In the intervening period between…

Ocean May Be Melting Totten Glacier Says Study

Ocean access to a cavity beneath Totten Glacier in East Antarctica http://www.nature.com/ngeo/journal/v8/n4/full/ngeo2388.html Totten Glacier, the primary outlet of the Aurora Subglacial Basin, has the largest thinning rate in East Antarctica1, 2. Thinning may be driven by enhanced basal melting due to ocean processes3, modulated by polynya activity4, 5. Warm modified Circumpolar Deep Water, which has…

NASA | 2014 Warmest Year On Record

The year 2014 now ranks as the warmest on record since 1880, according to an analysis by NASA scientists. Nine of the 10 warmest years since modern records began have now occurred since 2000, according to a global temperature analysis by scientists at NASA’s Goddard Institute for Space Studies in New York. 2014’s record-breaking warmth…

Rivers of meltwater on Greenland’s ice sheet contribute to rising sea levels

Using satellite and field work after an extreme melt event in Greenland, a UCLA-led study finds that melt-prone areas on its ice sheet develop a remarkably efficient drainage system of stunning blue streams and rivers that carry meltwater into moulins (sinkholes) and ultimately the ocean. However, the team’s measurements at the ice’s edge show that…
