Hidden lakes drain below West Antarctica’s Thwaites Glacier
Drainage of four interconnected lakes below Thwaites Glacier in late 2013 caused only a 10 percent increase in the glacier’s speed. The glacier’s recent speedup is therefore not due to changes in meltwater flow along its underside.

Atlantic Ocean’s slowdown tied to changes in the Southern Hemisphere
Unlike in the movies, and in some theories of climate change, the recent slowdown of Atlantic Ocean circulation is not connected with the melting of the Arctic sea ice. Instead, it seems to be connected to shifts around the southern tip of Africa.

CO2 record at Mauna Loa, the music video: The sounds of climate change
University of Washington scientists have put world’s longest-running measure of atmospheric carbon dioxide to music. The result is a 90-second rendition of human-induced climate change: The video project was done by Judy Twedt, a UW doctoral student in atmospheric sciences, and Dargan Frierson, a UW associate professor of atmospheric sciences and amateur musician. Their techno…
