This years’ summer institute was a re-imagining of how to engage across disciplines around an important climate issue of the day. We explored climate extremes, as seen in marine and continental heatwaves, precipitation and hydrology, and related equity issues. Registration closed Sept. 1, 2020.

Most days ran from 10:00am to 12:30pm and included

• (Pre-recorded) Presentations by invited speakers with introductions by faculty and graduate student session leads
• Break out group conversations
• Live panel discussion
• Lightning talks
• Poster session

Registered participants will be emailed the links to our zoom session and to poster/discussion session breakout rooms the day before each session. Watch for Monday’s links Sunday afternoon, Sept. 13.

Wed at 4:30 PM “PCC Trivia Night: Equally Trivial and Extreme” While we recognize that nothing could replace the feeling of being together in person together at Friday Harbor, PCC GSR Greta Shum organized an evening of trivia.

Suggested readings are being compiled for each session. We encouraged all, but especially graduate students and postdocs, to read and discuss prior to the workshop.
