There’s a lot going more on in the skies that’s affecting climate than just increasing CO2! Come hear about some surprising aspects of climate change from local atmospheric scientist Sarah Doherty. Sarah will talk about how particles in the atmosphere -- like smoke from fires and pollution from engines and industrial activities — are affecting our climate, how their influence on climate differs from that of greenhouse gases like CO2, and how we might leverage these effects to reduce global warming and the negative impacts of climate change.

Sarah Doherty is a Senior Research Scientist studying climate at the University of Washington, where she received her PhD in 2001. Her interest in atmospheric science began with a year of work in Antarctica, where she was helping make measurements to better understand the ozone hole. Since getting her PhD, much of her research has involved making measurements of smoke and pollution in different parts of the world, including off the coasts of Africa, China, India and the Arctic, and understanding how they affect climate. She has also been involved with multiple scientific assessments, including the U.S. National Climate Assessment and two international assessments of the state of the ozone layer. In her free time, she likes to spend her time skiing, kayaking, biking and paragliding — and any chance to enjoy this beautiful area where we live.
