Antarctica’s expanding sea ice may paradoxically be explained by the phenomenon of melted ice forming plumes of cold water meeting the surface and thus causing an increased sea ice coverage.

The Doha Climate Change conference has ended 24 hours later than intended, & sill without a deal that binds the US, China & India. On a positive note the Kyoto Protocol (which is due to expire later this Year) has however been extended till 2020, this however is of little real consequence as countries like the US have never ratified the original Kyoto Protocol.
A new study by NASA and ESA (European Space Agency) shows that ice in both Polar Regions is melting at an accelerating rate (up to 5 times the rate of a few years ago).
The study was produced by an international collaboration — the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE) — that combined observations from 10 satellite missions to develop the first consistent measurement of polar ice sheet changes. The researchers reconciled differences among dozens of earlier ice sheet studies by carefully matching observation periods and survey areas. They also combined measurements collected by different types of satellite sensors, such as ESA’s radar missions; NASA’s Ice, Cloud and land Elevation Satellite (ICESat); and the NASA/German Aerospace Center’s Gravity Recovery and Climate Experiment (GRACE).
