I recommend having a look at the Arctic Report Card:

Sobering stuff. I encourage anyone and everyone to consider blogging about anything in this report - there's plenty in there, could make up a series of posts. I'd love to do it but I'm simply swamped in a whole bunch of different SkS projects at the moment. In particular, I would love to expound on the latest melt in Greenland:

 

Cumulative net annual area changes for the 35 widest marine-terminating glacier outlets to the Greenland ice sheet. Year 2010 net area changes are shown with and without the Petermann glacier loss. The trend without the Petermann loss is illustrated by the triangle in year 2010.

Check this out:

"The corresponding time-scale of thermal response is of the order of years-decades, in contrast to conventional estimates of thermal response time-scales based on vertical conduction through ice (∼102–3 m thick), which are of the order of centuries to millennia. We show that CH warming is already occurring along the west coast of Greenland. Increased temperatures resulting from CH warming will reduce ice viscosity and thus contribute to faster ice flow."

Once we figured out the melt water transit through the ice, the revision of the warming scale seems pretty unavoidable. Wow.

Interesting to note that the source institution is Cooperative Institute for Research in Environmental Science (CIRES), which is also where Pielke hangs his hat.

Wonder if he'll have anything to say about that bit of news?
