As the frontier of Arctic permafrost recedes, how much carbon dioxide and methane is released?

That's the question INSTAAR PhD candidate Kevin Rozmiarek is hunting down in Alaska in the latest episode of "Ages of Ice." Read more here or stream the show on PBS!

Ancient birch DNA & bacterial lipids in Icelandic lake sediments reveal how shrub ranges expanded as temps rose. The local findings help predict how shrubs will expand across many high latitude areas with future warming, a change that lowers albedo & amplifies warming www.nature.com/articles/s43...

Satellites may be missing the most extreme phytoplankton events in our oceans. New research from Clow, Lovenduski, Mogen, & their partners simulates satellite observations within an Earth system model to reveal a fuller picture of the base of the marine food web. www.colorado.edu/asmagazine/2...

๐ŸงŠ ๐Ÿ’งThawing permafrost can leave a lasting mark on Antarctic streams. New research from the McMurdo Dry Valleys by Anna Wright & her team finds that erosion from thawing permafrost shifted stream chemistry, with effects still evident a decade later.
