Science Faculty Lecture Series: Clouds and Climate Change Featuring Associate Professor Jessica Kleiss

This presentation is the final lecture in a three-part Science Faculty Lecture series being offered this fall. Keep an eye on our virtual events webpage for details on future presentations. Clouds and Climate Change Presented by Associate Professor Jessica Kleiss Join Associate Professor of Environmental Studies Jessica Kleiss as she discusses clouds and their impact as a source of uncertainty in climate model forecasts. Clouds currently account for the greatest source of uncertainty in climate models because clouds can exert both a warming and a cooling effect on Earth’s climate and are involved in many positive and negative feedbacks, amplifying the effects of clouds in the models. In this talk, Professor Kleiss will summarize some of the fascinating ways that clouds interact with earth’s climate, and some of the challenges with model representations. This understanding has inspired a range of geoengineering approaches that aim to artificially mimic clouds’ cooling effect on earth and thus delay global warming. She will discuss the potential benefits and drawbacks of geoengineering approaches in the context of other possible climate actions.
