Public Lecture Event

Title: Past Climates Inform Our Future

Speaker: Professor Jessica Tierney (University of Arizona)

Bio: Jessica is a Professor at the University of Arizona. She studies past climate change (paleoclimatology) to learn how the Earth system works and what's in store for the future. Her research group focuses on studying past climates over a variety of timescales, using organic geochemical techniques and statistical climate reconstruction. She is a Packard Foundation Fellow, an American Geophysical Union Fellow, recipient of the NSF Alan T. Waterman award, and a lead author on the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment report.

Image below: Both past (top) and future (bottom) climates are colored by their estimated change in global mean annual surface temperature relative to preindustrial conditions, ranging from blue (colder) to red (warmer). “Sustainability,” “Middle road,” and “High emissions” represent the estimated global temperature anomalies at year 2300 from the Shared Socioeconomic Pathways (SSPs) SSP1-2.6, SSP2-4.5, and SSP5-8.5, respectively. In both the past and future cases, warmer climates are associated with increases in CO2 (indicated by the arrow). Ma, millions of years ago.
