We annotated some of the most, er, interesting lines in the DOE's new climate report with the help of scientists.

We fact-checked the Trump administration’s climate report
Scientists say the report cherry-picks key data and misrepresents the state of climate research.

🎉 New CATCH publication by @thorbarra.bsky.social et al. This work highlights key open questions in cold-region atmospheric chemistry - from polar sulphur emissions to wintertime haze. Check it out here 👉 pubs.rsc.org/en/content/a...

Atmospheric chemistry is really cool and I wish there was more of it taught in regular chemistry classes. Low-temperature radical reactions in the gas phase are so fascinating! Then add rxns in cold water, on mineral surfaces, and in incredibly concentrated salts/acids. It is such an amazing field.

I owe much to this country: the chance to build a career, a life, make friends, be part of a community, and now to educate others. There is much to stand up for so others will have these same opportunities!

E.P.A. Targets Dozens of Environmental Rules as It Reframes Its Purpose
Lee Zeldin, the E.P.A. administrator, said the agency’s mission was to make it cheaper to buy cars, heat homes and run businesses.

Many, many people are reaching out with questions about the impact of the LA fires on their homes and environment. There are some things we can say based on the research that was done after the Marshall Fire in Colorado. Here is a short thread to summarize what was learned. @ciresnews.bsky.social

Sadly, this story about our work in Chemical & Engineering News a few days ago is very timely again due to the #Palisades and #Eaton fires. bsky.app/profile/cenm...
“The impact of smoke can be retained inside homes for a lot longer than you would expect, so the impact of the fire is not gone after the fire is out,” says atmospheric chemist Joost de Gouw of CU Boulder. cen.acs.org/environment/... #chemsky🧪 #scinews
Compounds from wildfire smoke persist inside unburned homes
Researchers find that people returning to their homes after a Colorado fire were probably exposed to many aromatic VOCs

Also out this week: @andrewrjensen.bsky.social published VOC data from LA from Summer 2022. He found that VOC emissions were lower than in previous studies, but OH chemistry is now faster. As a result, ozone and oxidized VOCs are not lower than in the past. doi.org/10.1029/2024JD041812
