Here's the full abstract. Note that 1 of 7 computer models showed total ice melt by 2040... the worst case scenario. Gotta love how the media grabs the flashy stuff.

Abstract
We examine the trajectory of Arctic summer sea ice in seven projections from the Community Climate System Model and find that abrupt reductions are a common feature of these 21st century simulations. These events have decreasing September ice extent trends that are typically 4 times larger than comparable observed trends. One eventexhibits a decrease from 6 million km2 to 2 million km2 in a decade, reaching near ice-free September conditions by 2040. In the simulations, ice retreat accelerates as thinning increases the open water formation efficiency for a given melt rate and the ice-albedo feedback increases shortwave absorption. The retreat is abrupt when ocean heat transport to the Arctic is rapidly increasing. Analysis from multiple climate models and three forcing scenarios indicates that abrupt reductions occur in simulations from over 50% of the models and suggests that reductions in future greenhouse gas emissions moderate the likelihood of these events.
a) Operating marine radars on vehicles is illegal.
b) It messes with our X-band research radars out in tornado alley.
Thanks for not using a marine radar!

Hate to break it to you, but DSLR's can't take full motion movies. Second of all, why are you downloading images tethered? Get a usb 2.0 card reader!
Agreed... I like the old UI with JUST the buddy list. I couldn't find any options to turn off account/active status tabs. Talk about annoying.
