Proud to be part of the Expert Working Group on Climate Change and Health that just put together a report summarizing the evidence of health harms of climate change to date. Report is here: zenodo.org/records/1728... 🛟 #climatesky

This is why we fund scientists to study things like oyster slobber even if you don’t think it sounds important

I would like to rebrand climate change as "fossil fuels taking away your temperature freedom" #greensky, 🔌💡 | 🛟 #climatesky How do I do this? Do I submit a formal application somewhere?

Another expert review of the science behind the endangerment finding, this time from health professionals. they conclude that CO2 emissions "pose a clear and indisputable danger to human health and well-being." drive.google.com/fil...

breaking from me: the trump administration just suffered its first major loss in court over its onslaught on offshore wind the revolution wind project can now resume construction after a federal judge found its developer orsted was likely to win against the trump order to stop work @heatmap.news

I can confirm the Nextgen Acelas are really nice.

The Science of Delay The lesson of PFAS is the same lesson we should have learned from lead, asbestos, and air pollution: if we wait until the evidence is definitive, we’ve waited too long.

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report. This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it. Example: refuting one sentence.

My lab's been attacked by an anti-wind group and their lawyers. They threatened the science funding of my whole university, to shut me and my undergraduate research assistants up. NYT just covered it. 1/n www.nytimes.com/2025/08/25/c...

Costa also issuing the same warning

This is fucking crazy! The offshore wind farm is almost finished!

Affordability is an issue everywhere, so everywhere and anyone can benefit from improved bicycle infrastructure. #bikes

Grok showed up in my Tesla this morning, and started speaking to me without me trying to trigger it. I saw a tab called "conspiracy theories", clicked it and asked Grok about climate change. This is what Elon Musk is telling Tesla drivers about climate change.

Love this. Honestly, the env. ethics, env. philosophy, and globalization and environmental policy classes I took in college did as much to influence me as a scientist as my science classes did. theconversation.com/studying-phi...

Interesting new paper from @energymorgan.bsky.social et al. "Households that dont electrify may bear a 46% increase in gas bills on average over the next 15 years (relative to current costs). Targeted electrification may help to alleviate energy burdens." #enegrySky www.nature.com/articles/s41...

Prediction: as electricity costs (continue to) rise in coming years, Trump & the right will falsely blame clean energy & the quiescent US political press will dutifully amplify that message. A coherent, competent communications apparatus would see that coming & do something to forestall it ...

A very good ad, and some very good points!!

Not at all a coincidence that this type of clean-energy comms - which presents a positive case in forceful terms rather than trying to dance around the issue - is coming almost exclusively from non-US firms. The comparison tells us a lot about why the IRA failed. More below: 1/9

Why did I let Outlook update? The ML is clearly trained off its own emails so it predicts to fill in with its own default signature. I am going to regret this...

I've been getting a lot of requests for comments on the DOE report "A critical review of the impact of U.S. greenhouse gas emissions on the U.S. climate". Here are some initial thoughts. More will come later.

I listened to the most recent Ezra Klein where he interviewed @jessedjenkins.com and @janeaflegal.bsky.social on decarbonization and there was one very revealing bit where Ezra started to ask if ChatGPT could do the grid impact studies for the interconnection queue podcasts.apple.com/us/podcast/t...

New article our paper! www.bu.edu/sph/news/art... @busph.bsky.social @joeallenjoe.bsky.social and many others not on here. tl;dr, if you want to improve health and the climate, build renewables in places with coal!

Cleaning up aerosol pollution is critical for public health. But reducing aerosols is also unmasking warming from greenhouse gases - researchers here find this influence is strongest in populated places. 🧪

Congratulations to Bre on this fellowship! It's a very cool project!!

In today's Grad Fellow Friday spotlight, Breanna van Loenen zooms in 🔎 on harmful volatile organic compounds (VOCs) created during #FossilFuel production. With satellite data, she can better monitor these gases across the #US: www.bu.edu/igs/profile/...

"i asked grok" "i asked chatgpt" yeah well i asked carl sagan and he said the greatest enemy of knowledge is not ignorance but the illusion of knowledge 🧪

I would really appreciate it if the #abundance -erati could work on the problem of why US cities can’t have the same abundance and diversity of high quality restaurants as what is available in…. Waterloo, Ontario

haha, "whoops!"

I think it’s really important, when considering what we’re investing in for the future of decarbonization, to consider that techs depending on cooling water might simply be seasonally unviable under future climate conditions

A science fiction trope in real life! @realmsunknown.bsky.social

New paper. I wish this wasn't the case, but most progress on reducing US greenhouse gas emissions is likely spurious. Why? EPA underestimates methane emissions from oil and gas. Relevant today as Repubs vote to gut IRA's methane monitoring/mitigation program. 🧵 authors.elsevier.com/a/1lL4K_6se4...

They're* calling it the blackout bill. With new demands from AI, hotter temperatures, and the return of U.S. manufacturing, pulling back on clean energy deployment puts our electricity system at risk. *ok it's just me but still

Bad AI, bad. Go to your room.

Boston is so hot today, it's almost too hot to e-bike....

are the wireframes green and rendered at 15 FPS? please: of COURSE the wireframes are green and rendered at 15 FPS. does anyone have any ACTUAL questions? www.qwantz.com/index.php?co...

There it is. The first ever Heat Advisory issued in Alaska. This is the first year it has been an option. @alaskawx.bsky.social

Is nobody live-skeeting the EPA press event?

'tis the season to remind everyone that "Wet Bulb Globe Temp" is what we should be using for heat risk. Here's today: LEFT: temperature map (looks pretty good, minus limited parts of desert areas) RIGHT: WBGT (hi, northeast!) Explainer in 🧵

Mission statement:

Also: PJM adjusted how 'firm' it thinks natural gas plants are—not as firm as they thought, given significant correlated forced outages & derates during extreme hot & cold periods! So in short: gas isn't as realiable as we thought, and PJM is constraining pace of new wind, solar & battery build out.

Why are our electric bills going up about 20% in New Jersey and across the PJM region? This is why: electricity demand is growing fairly rapidly now, and we're not adding new supply fast enough to keep up. Why? Mostly because PJM itself is too slow to connect new generation & storage!

Harvard researcher Dr Sarah Fortune was only two years away from creating a vaccine that could have saved the 1.25 million people killed each year by tuberculosis. But last month, she received a letter telling her that the $60 million grant funding her research was being halted by President Trump.

You know what was an awesome abundance agenda? The Green New Deal.

The Environmental Protection Agency has drafted a plan to eliminate all limits on greenhouse gases from coal and gas-fired power plants in the U.S., according to internal agency documents reviewed by The New York Times.

Definitely not a legal expert but does this EO mean studies using private medical records now can’t be used for regulation? If so, this may hit all the evidence underlying air pollution regs www.whitehouse.gov/presidential...
