This Mosaic Of Satellite Images Shows Antarctica Like Never Before
2014-09-02 04:45:00| Climate Ark Climate Change & Global Warming Newsfeed
Gizmodo: The picture above shows a top-down view of Antarctica, the freezing southern end of our planet. Except that it's not a single picture. It's a mosaic of 3,150 satellite images mashed together to form one giant image. The images, which were created by MacDonald, Dettwiler and Associates, which manages the RADARSAT-2 satellite on behalf of the Canadian Space Agency. They're hosted by the Canadian Cryospheric Information Network, at the University of Waterloo, which maintains the Polar Data Catalogue,...

Sea-level surge at Antarctica linked to icesheet loss
2014-08-31 17:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: Sea levels around Antarctica have been rising a third faster than the global average, a clear sign of high meltwater runoff from the continent's icesheet, scientists said on Sunday. Satellite data from 1992 to 2011 found the sea surface around Antarctica's coast rose by around eight centimetres (3.2 inches) in total compared to a rise of six cm for the average of the world's oceans, they said. The local increase is accompanied by a fall in salinity at the sea surface, as detected by research...

MIT Scientists Explain How Global Warming is 'Temporarily' Cooling Antarctica
2014-08-25 16:07:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World: Massachusetts Institute of Technology researchers explain why global warming has led to Arctic losing sea ice, but the same has not been observed in Antarctica. Over the past few years, Arctic has shown considerable reduction in sea ice levels due to global warming. However, Antarctica has cooled and has even gained some ice recently. A new study suggests that ocean circulation can explain why the polar regions have different reactions towards rise in earth's temperature. John Marshall, the...

Antarctica & Greenland Losing Ice at Fastest Rate Ever Recorded
2014-08-21 18:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Environment 360: Ice sheets in Greenland and Antarctica are losing mass at an unprecedented rate of 500 cubic kilometers per year enough ice to cover the Chicago metropolitan area with a layer of ice 600 meters thick according to German researchers. Using data from the European Space Agency's CryoSat 2 satellite from 2011 to 2014, the team created the most detailed maps to date of ice elevations across Antarctica and Greenland, accurate to a few meters in height. The results reveal that Greenland alone is losing...
Oh, Great: Antarctica and Greenland Are Melting Faster Than Ever
2014-08-21 16:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Motherboard: Oh great, ice sheets in Antarctica and Greenland are melting at the fastest rate in recorded history. A group of researchers in Germany spent about three years measuring the two ice sheets melting, and figured out that with the two sheets combined, theyre thinning at the rate of about 500 cubic kilometers every year, according to research published yesterday in The Cryopshere. When we compare the current data with those from the ICESat satellite from the year 2009, the volume loss in Greenland...
