Good to see a second state follow Arizona's lead with a state-level chief heat officer position! www.wbur.org/news/20... #extremeheat #heatresilience

Mass. is second state to appoint heat resilience officer

Massachusetts just appointed a heat resiliency officer to coordinate with state government agencies and work with communities to "prepare for rising temperatures, protect public health and reduce the impacts of extreme heat."

Over the years, @sarameerow.bsky.social and I have evaluated many plans to see how well they address extreme heat. In this Global Disaster Preparedness Center project, we explored how heat action plans are actually being implemented and asked officials about their perceived effectiveness.

📬 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

How cities are fighting back against the 'heat island effect'

As temperatures rise, researchers are rethinking how cities measure and respond to urban heat. But experts say successful solutions require finding solutions tailored to local conditions rather than relying on one-size-fits-all fixes.
