In a speech to the UN yesterday, President Trump falsely claimed that climate change is a "con job," that renewables are "too expensive," and that coal is "clean." @apnews.com takes a closer look at the president's statements and the scientific reality.

COUNTRY ANALYSIS: We have downgraded the #US climate action to "Critically insufficient" - it's the most aggressive, comprehensive and consequential climate policy rollback the CAT has ever analysed. 🔗 bit.ly/CAT_US

I have a new @nytimes.com guest essay w/ @davidkeith.bsky.social about sunlight reflection. We note its not a solution for climate change and at best a band aid to treat systems, and suggest if its ever done it should only be to replace the cooling from air pollution today:

Microsoft gave guidance on H1Bs to its employees last night

i don’t think people on bluesky understand the severity of this situation. i woke up to literally hundreds of texts from friends and family thinking about either moving back home to india or applying to other countries for jobs. this includes me.

Global warming has accelerated since the 2000s. Sea level rise is also accelerating. @hausfath.bsky.social @dananuccitelli.bsky.social @climateconnections.bsky.social yaleclimateconnections.org/2025/09/clim...

It’s remarkable that with everything else that’s raging, climate and energy still managed to dominate the legislative session that just wrapped in Sacramento. My recap: legal-planet.org/2025/09/16/w...

We're halfway between the IPCC 6th and 7th Assessment Reports, and an international team of 61 scientists updated some of the key metrics used in the reports. As I wrote for @climateconnections.bsky.social, the findings were pretty bleak, but there are some glimmers of hope 🧵 (1/6)

🔥 The world’s top climate scientists have found that global warming is accelerating. Oceans are rising faster than ever, and the 1.5°C target is slipping away, but there’s still a narrow path forward. #ClimateAction

EV sales year to date one of these is not like the others... Global: 12.5 million, up 25% China: 7.6 million, up 25% Europe: 2.6 million, up 31% North America: 1.3 million, up 6% Rest of world: 1.0 million, up 44%

On Friday, the EPA proposed killing the program that requires large factories, refineries, and power plants to report their carbon emissions. But its plan would also hobble the carbon capture industry & basically prevent anyone from using the tax credit. New from me: heatmap.news/energy/epa-g...

okay @robinsonmeyer.bsky.social won the email subject line game today, this is 🤌 (good excuse to plug the very good @heatmap.news newsletter too!)

Join us this Saturday at 10 PT/1 ET for CCL's September Monthly Meeting, featuring climate scientist Dr. Daniel Swain! During September's meeting, Dr. Swain will help us understand how climate change is impacting wildfires🔥 👉 Visit cclusa.org/monthly-call/ for more information.

The #FixOurForests Act uses smart, science-based solutions to restore forest health and reduce wildfire risk, while preserving important environmental standards. That's why we've joined 21 other organizations urging the Senate to pass the bill: citizensclimatelobby.org/blog/news/cc...

"Maybe in a few days the DOE will announce the details of a credible review process, including the appointment of expert and unbiased review editors. Maybe pigs will fly. Maybe I’ll win the 2025 AL Cy Young Award. Who knows which of these equally likely things will occur." 😂

On The Climate Brink: More about the DOE Climate Working Group report. The Fix Is In: Without independent review editors, their “peer review” process is a sham. Science and humanity deserves better.

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

Massive lightning outbreak up the Central Valley into parts of the Bay Area this morning. Get ready for a ton of wildfires. Weather impact day across California. #CAwx

Our 400+ page comment on the DOE climate working group report is now out. Our conclusion: The merchants of doubt are back, and they're coming for climate science.

With sufficient data in for July, the year-to-date estimate of India's fossil CO₂ emissions is now +0.3%. See: robbieandrew.github.io/india/

AMS released a statement on climate change today that points out five foundational flaws with the Department of Energy's 2025 climate report: www.ametsoc.org/ams/about-am...

Many of the Inflation Reduction Act's climate measures are expiring soon. But while they were in place, they put us on track to save about 1 billion tons of carbon dioxide pollution over the next decade! "Every ton of avoided carbon pollution makes a difference," says @dananuccitelli.bsky.social.

"The EPA has both the authority and the responsibility to act," says @dananuccitelli.bsky.social. "Americans cannot afford a retreat from science, law, and common sense in the face of a rapidly accelerating climate crisis.” More about CCL's comment to EPA: citizensclimatelobby.org/blog/democra...

🐛 @dananuccitelli.bsky.social explains why it is wrong to revoke the 2009 #endangerment finding (which essentially says that greenhouse gases affect the climate 🌎). This is such a bold move that @cclusa.org submitted a public comment. Read more here ⬇️.

I checked the claim of the DOE report that sea level is rising at a lower rate than predicted by IPCC: it is false. For 2030, the IPCC AR6 predicts a best estimate 9-10 cm relative to 1995-2014 (Table 9.9). The satellite data show a rise of 74 mm until 2025. At this rate that will be 93 mm by 2030.

Trump’s tax, trade, and energy policy is distorting the American economy and robbing it of its complexity. We are becoming a country that only makes crypto, corn, and chemicals. I wrote about it for @nytopinion.nytimes.com: www.nytimes.com/2025/08/10/o...

Looks like 2025 is now almost certain to join the pack of 2023 and 2024 for the three hottest years in more than a century of global data. The scoop from @drjeffmasters.bsky.social and me: yaleclimateconnections.org/2025/08/july...

It’s amazing how every single sentence coming out of Zeldin’s mouth in defending his proposed repeal of EPA’s endangerment finding is a lie. To understand the truth, see: yaleclimateconnections.org/2025/08/the-...

I read EPA’s 302-page proposal to nuke the endangered endangerment finding so that you don’t have to, and wrote about what the insanity all means for @climateconnections.bsky.social. Thanks to @gregdotson.bsky.social, @hausfath.bsky.social, @michaelemann.bsky.social for the input. Article & 🧵(1/14):

The crazy thing is that Burgum's last job was as governor of North Dakota, which gets 36% of its power generation from wind, sixth-highest of any state. But he's just become another Trump yes man. It doesn't matter how stupid and harmful the decision is to Americans, Trump gets what Trump wants.

HUGE: The Trump administration will no longer permit any solar or wind projects on federal lands unless they produce more energy-per-acre than coal, gas or nuclear power plants. Solar and wind literally produce less energy per acre, so simply this may just kill off any project on federal lands.

This action really is insane. These people don't care about reality at all.

Motherfucking wind farms…

Each chapter follows the same pattern. Establish a contrarian position, cherry pick evidence to support that position, then claim that this position is under-represented in climate literature and the IPCC in particular. Include a bunch of references, most of which don't support the central argument.

Revoking EPA’s endangerment finding – the keystone of US climate policies – isn’t simple and could have unintended consequences theconversation.com/revoking-epa...

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.

That new usual suspects (Curry, Spencer, Christy, McKitrick, Koonin) Trump EPA climate denier report? (www.energy.gov/sites/defaul...)? I asked chatGPT to evaluate it. It had no trouble producing a succinct and convincing refutation:
