📬 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

📢 Heat impacts all communities, not just large cities. In our new American Planning Association PAS Memo, we explain the need for rural heat resilience and outline actionable principles and strategies for rural communities and small towns. www.planning.org/pub... #extremeheat #heatresilience

It's hot out there! Tucson just broke our earliest 100°F on record today, previously set on April 11, 2025. Average first 100°F is supposed to be mid-May. Surface temperatures are much higher of course, this was a random reading of an asphalt road I took. #heatwave #azwx #extremeheat
