A day in the life of a planning professor. 😅 Stay tuned... 🐻⬇️

The first paper in the U.S. Climate Collection, an AMS-@agu.org initiative supporting assessment-ready climate science, is out! Published in #BulletinAMS & Earth’s Future, the paper highlights key needs for future climate assessments and decision-making. Read more: https://bit.ly/46CTg30

I'm honored to contribute to this commentary w/ colleagues from across the United States. Big thank you to Melissa Kenney @costasamaras.com @bobkopp.net for their leadership & public service in the advancement of climate scholarship. READ HERE --> agupubs.onlinelibrary.wiley.com/doi/10.1029/...

NEW PAPER: In a new paper, jointly published in @agu.org Earth's Future & @ametsoc.org BAMS, and co-led by Melissa Kenney, @costasamaras.com and me, 175 authors outline priorities to guide the future of scientific assessments of climate change in the United States. 🧵

Research Priorities for Robust Climate Assessments in the United States

Remember the Sixth National Climate Assessment (#NCA6)? In April 2025, all of its authors were released, and the report was halted. I was a Southwest chapter author. Many of us former NCA6 authors just published what we could in its place. doi.org/10.1029/2025...

This summer was hot. August shattered global heat records

Scientists say that August was the hottest month ever recorded globally. In the U.S., summer temperatures also shattered heat records.

Cities are adopting heat action plans faster than ever. We still have almost no evidence that they work. In our new report, we coded 34 plans, evaluated 12 in depth, and interviewed officials. We found that cities track activities, not outcomes. heatshed.substack.com/p/we-dont-kn... #heatactionplan

We don't know if heat action plans are working

A new international evaluation finds that cities track what they did, not what they changed.

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.
