Department Seminar Series
The 2022-23 Department Seminars will be hosted virtually via Zoom and will take place on Thursdays at 4:00 p.m. The Zoom link for each individual seminar will be sent out in the weekly seminar announcement. If you do not receive these announcements and would like to join us for our virtual seminar, please send us an email so we may send you the appropriate Zoom webinar link. If you would like to be added to the seminar announcement list, please contact Kaleigh Swift at swift095@umn.edu.
If you missed a seminar, make sure to check our department YouTube channel for the recording. Seminar recordings are posted by 12:00 pm on the Friday following seminar. Please note, not all seminars will be posted as it is up to the discretion of our speakers.

How will the tropical Pacific respond to global warming? The importance of timescale when considering apparent paleo-paradoxes
Abstract
Several oceanic and atmospheric mechanisms have been put forward to describe the response of the tropical Pacific to global warming. Still uncertainties persist in their interaction and relative importance, with projections varying substantially across climate models. When we turn to the last time in Earth’s history that atmospheric CO2 estimates exceed 400 ppm, the Pliocene, several apparent paradoxes related to the equatorial east-west sea surface temperature (SST) gradient appear. These paradoxes cloud our view of the tropical Pacific during the Pliocene and its utility as a potential analogue for future warming. However, as I will cover in this talk, when proper consideration is given to the timescales associated with the oceanic and atmospheric mechanisms that support tropical Pacific climate variability, several of these apparent paradoxes can be resolved.
Virtual via Zoom.
