Traveling Particles

Chalif, a graduate student and technician in professor Eric Osterberg’s Ice, Climate, and Environment Lab, has been featured in Newsweek and Earth.com articles this week about his research into the impact of pollution on the Arctic’s atmosphere. Chalif and Osterberg—along with Dominic Winski ’09, Ursula Jongebloed ’18, and several other scientists—co-authored a new study in the journal Nature Geoscience that links atmospheric change in remote arctic regions to fossil fuel pollution in populated parts of the world. 

"Our study is a stark example of how air pollution can substantially alter atmospheric chemistry thousands of miles away. The pollution emitted in Asia or Europe was not contained there," Chalif said.
