I shared some ideas with @gothamist.com to help get New York back on track with its climate goals given the political headwinds of the moment.

Why are flood barriers paramount, will more measures be needed in light of sea level rise, and what are other cities doing that NYC has considered? Our @columbiauniversity.bsky.social chief climate & sustainability officer @dzarrilli.bsky.social discusses these questions with @weather.bsky.social.

"About the only certainty, Mr. Zarrilli said, was that a tariff of 10 percent or more would add costs that would be passed on to consumers to some extent." www.nytimes.com/2025/02/03/u...

"As a warming planet delivers more wildfires, hurricanes and other threats, America’s once reliably boring home insurance market has become the place where climate shocks collide with everyday life." www.nytimes.com/interactive/...

NYC buildings have been getting steadily more energy efficient since the city passed its landmark building emissions law, LL97. 92% of covered buildings are now within the 2024 emissions limits (vs 88% last year). Fresh number crunching from Urban Green Council (h/t @petesikora.bsky.social):

“Any of these projects faltering is just going to keep New York City reliant on an aging and dirty fossil fleet,” @dzarrilli.bsky.social tells @emilypont.bsky.social. How Attentive Energy's offshore wind pause could derail New York's climate plans:

58% of New York's electricity coming from sources other than fossil fuels right now - the highest I've happened to notice... ⚡

"There are all sorts of ways in which, if New York really stepped up to the plate in a vigorous way, it could have a big ripple effect, not just in the United States but around the world." #CLCPA www.nytimes.com/2024/11/29/n...

Ouch Thankfully, two Tier 4 projects were awarded, with CHPE already under construction… ⚡️

Great reporting by Karl Mathiesen on #COP29 - and the promises and flaws of multilateral climate negotiations... www.politico.eu/article/clim...

"The idea assumes there is significant debate among scientists that humans are driving the planet to dangerous levels of warming through the burning of fossil fuels. There isn’t." www.eenews.net/articles/tru...

#but "Scientists say every fraction of a degree of warming caused by fossil fuels brings greater risks from deadly heat waves, wildfires, drought, storms and species extinction. But investors are focused on making money over months and years." www.nytimes.com/2024/11/18/b...

NYC upgrades to a drought warning. Conserve water, folks! 🌧️ www.nydailynews.com/2024/11/18/n...

The youth cross country world has descended #onStatenIsland today for the regional championships at the Ocean Breeze Athletic Complex… #USATF Good luck to all the runners!

After the driest October on record, NYC is now in a drought watch, with brush fires popping up and causing poor air quality in the five boroughs. I spoke with Roger Clark at NY1 today about what it all means - and the climate connection. Check it out ⬇️ ny1.com/nyc/all-boro...

At Columbia, we are building on a rich legacy of research and knowledge to embed climate action and sustainability excellence into every aspect of our work. Check out this video to learn more: vimeo.com/1011032470 #ColumbiaClimateWeek #ClimateWeekNYC

⚡️ Check out my conversation with the NewYork ISO about New York's climate risk and the path forward on resilience, phasing out fossil fuels, and environmental justice. #PowerTrends www.nyiso.com/-/podcast-ep...

I talked with Fox Weather about the flooding in NYC, the state of our infrastructure, and the role of climate change in making these storms worse. Check it out: www.foxweather.com/watch/play-6...

Earlier this week, I joined Shannan Ferry on NY1 to talk about #ClimateWeekNYC, recent floods and fires, and how the pressure is building to phase out coal, oil, and gas. Watch it here: ny1.com/nyc/all-boro...

Join Columbia and the Greater Harlem Chamber of Commerce on August 9 for the fourth in a series of events focused on the growing risks of climate change and the important work to achieve environmental justice in Harlem. #HarlemWeek Register: https://events.columbia.edu/go/harlemweekclimatechange
