Greenland's melting is real: It is visible from space and from the ground. Radar reflectivity shows the signature of water instead of ice, temperatures went above melting point on top of three kilometers of ice, an anti-cyclone made months long summer holidays over the ice sheet, the albedo is down and giga tons of ice get lost every year. Next year's IPCC WG1 contribution will be an interesting reading in this context.-> continue reading
This report from last November remained a while in the local pipeline before getting blogged. It is a comprehensive and dense reading. Also it it is one of the longest - in terms of scrolling - webpage ever seen. I chose to zoomify it to get an overview and at a first glance I recognized all charts are going down. Except - still naturally - surface mass balance along the K-transect over elevation.
Everybody equipped with good pattern matching wetware will see a link to the sea ice extent graphs of the years 2007 and 2010.
Here are both highlights and a link of the report:
- Total ice sheet mass loss in 2011 was 70% larger than the 2003-09 average annual loss rate of -250 Gt y-1. According to satellite gravity data obtained since 2002, ice sheet mass loss is accelerating. -> continue reading
