Ankur Desai studies micro-climate data to better understand how plants and trees contribute to weather patterns on a local scale.

Steve Vavrus is an expert on global climate change, Arctic climate, Wisconsin climate, and extreme weather.

Sara Hotchkiss' research focuses on the paleoecology and history of vegetation, including ecosystem responses to past climate change.

Climate Change Symposium

Join us for UW–Madison’s 2025 Climate Change Symposium on Tuesday, Oct. 7, 2025 from 6:30–8:30 p.m. The Climate Change Symposium is an annual event that brings together experts and community members alike to explore timely issues in climate science. This year, our keynote and panel discussion will explore climate solutions for building resilient communities — both in the sciences and society.

To register and learn more, go to Climate Change Symposium.

The Center for Climatic Research focuses on interdisciplinary research regarding the Earth’s climate system, including the causes and impacts of historical, ongoing, and projected climate variability and change, with geographic focuses that span from local to global scale. The center’s diverse activities and societal contributions include the training of students and postdoctoral researchers as the next generation of climate scientists, development of guidance for state government and regional stakeholders regarding climate change impacts and adaptation, and advancement of scientific understanding of the coupled Earth system.

Tools for Tracking Climate Change

CCR scientists have developed easy-to-understand maps that show historical information and climate projections in Wisconsin and Midwest. The maps provide insights into how temperature, precipitation, length of growing season, and other variables might change in the future.

Excellence in Climate Science
