Record-breaking heatwaves and devastating wildfires across Europe serve as yet another call for urgent action in addressing the climate crisis. @columbiaclimate colleague @KKornhuber calls Europe a "heatwave hotspot"; I'm feeling the impacts in the U.K. reuters.com/article/us-europ…

So I was promoted to full professor as of 7/1. I want to thank everyone in my group for your efforts in helping me shape and realize everything we’ve done in the last 12 ish years. You cast your opportunity with me and it means the world to me. I hope I’ve done as well by you.
