The Billion Dollar Weather and Climate Disaster dataset is back and now at @climatecentral.org!

Through the first half of 2025, there were 14 separate billion-dollar weather and climate disasters across the United States, costing $101.4 billion. 1/2

Climate-linked escalation of societally disastrous wildfires Climate change and land mismanagement are creating increasingly fire-prone built and natural environments. However, despite worsening fire seasons, evidence is lacking globally for trends in socially ...

Published today: our new paper showing a 44-year trend of increasing global wildfire disasters (fatalities and economic losses) due to climate change-induced extreme weather. www.science.org/doi/10.1126/...

Agreed, it was a great one! We got a Monday afternoon slot this year, though, which feels better.

Screenshot of an ESS Open Archive preprint page. A green “Download PDF” button sits at top left. The title reads “Climate Experts’ Review of the DOE Climate Working Group Report.” Below are subject tags “Atmospheric Sciences” and “Climate Science,” followed by two listed authors. A “Preprint timeline” box shows “Submitted to ESS Open Archive” on 24 Sep 2025 and “Published in ESS Open Archive” on 29 Sep 2025. A citation block includes the DOI 10.22541/essoar.175745244.41950365/v2 and notes version v2 (processing). A right-side box says “Non-exclusive” and “No reuse.” A yellow banner at the bottom states: “This is a preprint and has not been peer reviewed. Data may be preliminary.”

Our comment to the DOE and EPA about the DOE Climate Working Group report is now posted on ESSOAR preprint server. It has a DOI and can now be cited!

Scientists link hundreds of severe heat waves to fossil fuel producers' pollution A new study finds dozens of heat waves would be "virtually impossible" without the activity of major fossil fuel producers, including oil companies.

Dozens of scientists find errors in a new Energy Department climate report More than 85 scientists say that a recent U.S. Department of Energy report is full of errors and misrepresents climate science.

Grateful to @andrewdessler.com for coordinating this (and keeping us on schedule)! I feel proud for having contributed to this monumental effort alongside some of my role models in this field. It felt necessary to respond to the report that was misleading at best and dangerous at worst.

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.

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.

Thanks to the Guardian for covering our efforts.

Law Firm Pressures Brown University to Erase Research on Anti-Wind Groups

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.

Factcheck: Trump’s climate report includes more than 100 false or misleading claims

First comprehensive fact check of the DOE ‘critical review’ of climate science..

Multiple pinocchios!

interactive.carbonbrief.org/doe-factchec...

A bunch of climate scientists, myself included, are currently devoting hours of unpaid and un-rewarded labor to fact-check the DOE’s mountain of bullshit for exactly this reason. They are engaged in a political project that demands explicit pushback.

DOE climate report response form We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me. We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.

🚨 If you're interested in working on a coordinated response to the DOE climate report, please enter your info on this google form 🚨

Please RT this so as many people see it as possible.

Contrarian climate assessment from U.S. government draws swift pushback Researchers say DOE report cherry-picks data to downplay threat of greenhouse gases

Contrarian climate assessment from U.S. government draws swift pushback | Science | AAAS www.science.org/content/arti...

nice article from @voosen.me

Claim: "Water vapor is a greenhouse gas!"
Reality: Yes, and there's more of it in a warmer atmosphere

-"CO2 is plant food!"
-pretty hard to eat when you're on fire

-"Climate has changed before!"
-We know, we told you that

-"Scientists don't know everything!"
- doesn't mean we know *nothing*

Same here!

Going to #AGU25? Today's the last day to submit an abstract to this session we're organizing on climate attribution science and its applications to real-world issues like climate litigation or loss and damage!

Correction to the headline here. It's not the reports that have disappeared - it's the globalchange.gov websites themselves.

The reports are still available buried in the NOAA archives. NCA5 is here: repository.library.noaa.gov/view/noaa/61...

New study w/ @climate-guy.bsky.social ! Increased evaporative demand due to climate change has increased crop irrigation demand; in the Central Valley, this additional irrigation demand is equivalent to ~11% of the region's observed groundwater loss.

⚠️Global warming caused by humans is advancing at 0.27°C per decade – the highest rate since records began.

This is one of the indicators updated every year by over 60 international scientists in the annual Indicators of Global Climate Change report – published today. doi.org/10.5194/essd... /1

Thanks for putting into words the feeling we’ve been struggling with, @climatehuman.bsky.social .

“climate breakdown is nothing more (or less) than the most planetary-scale symptom of the underlying collective trauma from five hundred unhealed, accumulated years of extractive colonial capitalism.”
