📬 ICYMI: I started a newsletter. It's called Heatshed, and it's about how we plan for and govern extreme heat. I've written for journals and op-ed pages for years. This is where I get to think in public at the speed the problem moves. #extremeheat #heatshed #heatplanning #heatgovernance

📬 Wrote a new post for my Heatshed newsletter on air conditioning in Europe and the U.S. and lessons we can learn from each other. I'll post monthly after this, but I had been mulling this one over all summer! heatshed.substack.com/p/air-condit... #airconditioning #extremeheat #heatwave
