Free Public Lecture: Earth’s Climate Trajectory, Past and Future

As atmospheric carbon dioxide levels climb higher than they have been in the last two million years, we face the challenge of adapting to and mitigating the effects of climate change. How do we know that humans are responsible for climate change? What effects of climate change can we see already? How can geology help understand what a future warm world might look like? In this talk, Dr. Tierney will take us through the past, present, and future trajectory of Earth’s climate and discuss how paleoclimatologists query the ancient record of climate change to improve our understanding of the future.

This is a free event. A complimentary wine and cheese reception will follow.

Dr. Jessica Tierney is an Associate Professor at the University of Arizona. She is a paleoclimatologist who uses geochemistry, climate models, and statistics to figure out how climate has changed in the past, so we can better prepare for the future. She has won awards for her work including the American Geophysical Union Macelwane medal for her contributions as an early career scientist and a David and Lucile Packard Fellowship. She is a lead author on the upcoming Sixth Assessment Report for the Intergovernmental Panel on Climate Change.
