Cecilia Bitz is a professor in the Atmospheric Sciences Department at the University of Washington, and she is is part of the UW Program on Climate Change and an affiliate of the Polar Science Center. Cecilia's research focus is on climate and climate change in the high latitudes, especially involving the cryosphere. She uses a variety of models for her research, from simple reduced models to sophisticated earth-system models. Cecilia's group has recently written papers about the delayed warming and sea ice change in the Southern Ocean, Arctic sea ice predictability and reversibility and the influence of black carbon surface deposition on Arctic climate. She has investigated climate change from geoengineering and has worked on understanding climate sensitivity. She recently chaired the advisory board of the US National Science Foundation's Office of Polar Programs and is presently on the advisory board of the Community Earth System Model project. She won the 2013 Rosenstiel award for Oceanography and Meteorology and the 2013 Ascent award for the Atmospheric Science section of the American Geophysical Union. Cecilia is an active volunteer and science adviser to Polar Bears International.
