Eric Steig is in The New York Times

The New York Times has been doing a series on Antarctica and the signals of climate change over the past few weeks. In Part 3 of their series, they talk about the culprit for the loss of ice around West Antarctica. Some point to the strengthening of the winds, churning up more warm ocean water. however, Eric Steig, Department of Earth and Space Sciences, mentions that "we’re not sure because we don’t have enough data, for long enough, to separate signal from noise".

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.

Former PCC member Hilary Palevsky discusses the meaning of science activism

Hilary Palevsky, a former member of the Program on Climate Change, talks about the meaning behind the March for Science. Palevsky states that it is important to listen "to the voices of the most marginalized people when we talk about how we stand up for science because in a lot of ways, the organization of the March for Science reproduced a lot of the same issues that have been long standing in the scientific community”.

David Battisti and Tom Ackerman talk about geoengineering in the NYT

David Battisti and Tom Ackerman of the Department of Atmospheric Sciences were quoted in The New York Times this past week. When talking about the uncertainty of putting aerosols in the atmosphere Battisti said it is “not obvious to me that we can reduce the uncertainty to anywhere near a tolerable level — that is, to the level that there won’t be unintended consequences that are really serious". Ackerman said that “we are doing an experiment now that we don’t understand" when talking about the risk of starting to geoengineer.
