Superstar Katey Walter, UAF student, IPY fellow, and now prof, was in the news again last week for getting an article published in Science. She and her co-authors propose that methane released from thawing lakes contributed a third to almost all of the increase in atmospheric methane during the past warm, interglacial period, and could have a big warming impact again.
Here's the Science abstract, and here's the story my paper did.
Walter was also featured last month by NPR.
In other news, NPR has a bit of a primer on the most important greenhouse gas, water vapor. And Doug O'Harra of Far North Science has a good explainer on this year's disappearing sea ice.
