Former PCC graduate student of ESS says goodbye to glaciers

Twila Moon, a PCC Fellow and former Department of Earth and Space Sciences graduate student recently wrote an article in Science talking about the the global retreat of glaciers. Moon states that "photographs and aerial and satellite images of glaciers show consistent, substantial, and anomalous retreat from the Antarctic Peninsula through Patagonia, Kilimanjaro, and the Himalayas to Greenland and the Arctic. Iconic glaciers—such as many in Glacier National Park, Montana—have already disappeared".

Surprising results with the atmosphere from looking at ice cores, bacteria and isotopes!

UW researchers, Lei Geng, Qiang Fu, and Becky Alexander published a study in the journal Nature that shows during large climate swings, oxidants shift in a opposite direction than researchers had expected, which means they need to rethink what controls these chemicals in our air. In their study, they analyzed slices from a Greenland ice core in the UW’s isotope chemistry lab. A new method was created to get a read on changes in the atmospheric oxidants.

Graduate Student Representative, Greg Quetin, has a new paper in the Journal of Climate

Department of Atmospheric Sciences Graduate Student and PCC Graduate Student Representative, Greg Quetin, recently published a paper in the Journal of Climate on the interaction of vegetation and global climate. The study found that the composition of ecosystems can be shaped by climate in order to take advantage of local environmental conditions. Moreover, the interaction between photosynthesis and temperature can respond to different climatological states. The combination of these two factors determines ecological-climate interaction and the pattern can provide a functional constraint for process-based models, helping to improve predictions of the global-scale response of vegetation to a changing climate.

UW Atmos and ESS collaboration—Arctic sea ice loss and natural variability

David Battisti, Edward Blanchard-Wrigglesworth, Stephen Po-Chedley, and Ryan Eastman of the Department of Atmospheric Sciences and Eric Steig of the Department of Earth and Space Sciences recently published a paper in Nature about the influence of high-latitude atmospheric circulation changes on summertime Arctic sea ice. The study found that a substantial amount of summer sea ice loss in recent decades was due to natural variability in the atmosphere over the Arctic Ocean.

UW Glaciologists uncover truths about hidden lakes on West Antarctica's Thwaites Glacier

UW Glaciologists, Alexander Huth and Ian Joughin,and Noel Gourmele of the University of Edinburgh used data from the European Space Agency’s CryoSat-2 to study a sudden drainage of large pools below Thwaites Glacier. Thwaites Glacier is one of two fast-moving glaciers at the edge of the West Antarctic ice sheet. The recently published study in The Cryosphere shows four interconnected lakes that drained in eight months. The glacier sped up by about 10 percent during that time, showing that the glacier’s long-term movement is fairly oblivious to trickles at its underside.

Ocean conditions contributed to unprecedented 2015 toxic algal bloom

“A study led by researchers at the University of Washington and the National Oceanic and Atmospheric Administration connects the unprecedented West Coast toxic algal bloom of 2015 that closed fisheries from southern California to northern British Columbia to the unusually warm ocean conditions — nicknamed “the blob” — in winter and spring of that year.” – Hannah Hickey
