10/9 4pm CDT: A life-threatening storm surge from #Isaias is expected from the Mouth of the Mississippi River to the Suwannee River, FL.
Residents under evacuation orders should leave immediately & follow advice from local officials. Conditions will deteriorate this evening.
"an even simpler explanation for the continued engagement: the implications of climate change and the related energy issues have only become more important"

I spoke with @mjchiusano about all of the amazing work happening on the NYC subway.
It's a remarkably resilient system but will continue to need creative thinking and massive investment to allow it to safely serve New Yorkers as rain events get more intense from climate change.

Nice writeup in State of the Planet on the community partnership event that @ColumbiaClimate and the Greater Harlem Chamber of Commerce held during #HarlemWeek2026.

After Hurricane Sandy demonstrated our vulnerabilities to climate change, we took action to build resilience. Now, across the five boroughs: "visible results of a multi-decade campaign to keep New York dry and safe in an epoch of rising seas and more violent storms." – at New York, NY

Great perspectives from @JDavidsonNYC
It takes all the tools in the toolkit to make New York safer against the full range of climate risks we face. And when you step back, you can see the full strategy coming together. – at New York, NY
I shared some thoughts with @IEEESpectrum on New York's data center moratorium. ⚡
Bottom line, we have a year to put in place a thoughtful and predictable process that enables growth without undermining our need for reliable, clean, and affordable energy. Let's not waste it.
Some professional news:
After over five years at @Columbia University, I’m stepping down as the Chief Climate & Sustainability Officer.
What’s next? Vacation! Then taking on a new and exciting set of climate resilience challenges. More on that soon enough… – at New York, NY
It has been a privilege to serve @Columbia since 2021. I am proud of what we have accomplished here together, from supporting the creation of the Climate School to accelerating the construction of all-electric university buildings and more!
And I won’t be totally gone from campus: I’ll still be teaching my course this fall on New York City’s climate policy since Hurricane Sandy in the @ColumbiaClimate School.
