Sorry, but disagree with @hausfath.bsky.social here. You open Pandora's box, you ain't closing it again. We've already seen with Paris that well intentioned international agreements do not translate into physical reality and SRM governance is a much harder problem. Zero is the only safe level. /1

Verbatim: "White House spokeswoman Abigail Jackson described Mr Swain as a "longtime Democrat donor who has spent hundreds of dollars supporting liberal politicians, including loser Kamala Harris, with radical climate policies that the American people have repeatedly rejected."

Last week at the Italy–France border: moist valley air rising and forming near-surface clouds, while a higher cloud layer (with a cloud base of around 3,500 metres) tries to grow by convection, but fails to reach the rain stage. Beautiful!

EXCITING NEWS! The Climate.us page has officially launched. Here you will be able to read more about us, our plan, updates, see what real people are saying, view our news coverage, and of course find ways to take action. We look forward to your continued support.

I'm not sure many folks realize just how persistent the warming from CO2 is. Here is a set of 1000-year climate model runs (using FaIR) simulating one year of CO2 emissions (40 gigatons in 2020); a millennia later the world has not cooled back down!

nice article from Nadir Jeevanjee (is he on bluesky?) about predictions climate models got right. successful predictions are the gold standard of science. 5 forecasts early climate models got right – the evidence is all around you theconversation.com/5-forecasts-...

I’m increasingly confident that these quotes are fully and intentionally fabricated, having searched extensively in both reports. The quotes are framed to suggest that the IPCC *concluded* that natural variability undermines attribution of anthropogenic climate change. FYI: It does not.

🌍 New today in Nature: Climate models need faster, more frequent data updates - here's how to do it 🌍 Today, a group of scientists, led by Vaishali Naik published a Comment in Nature calling for a major shift in how we support climate modelling. 🔗 www.nature.com/articles/d41...

“The Office of Management and Budget approved a fiscal 2025 spending plan for the National Oceanic and Atmospheric Administration that would claw back remaining funds at most of the agency’s line offices.”

📢📢 New preprint alert! 📢📢 Radiation is a key piece of climate models, but comes with a trade-off: use an accurate scheme (which is difficult to understand), or a simple scheme (which is not very accurate)... Here I introduce a scheme which bridges this gap! arxiv.org/abs/2508.09353

TL;DR, it only takes six simple equations to do (reasonably) accurate longwave radiative transfer in a GCM! Demonstrated for an Earth-like planet, but the approach could easily be extended to exoplanets!

The recent DOE climate science report misrepresents the work of many researchers. Carbon Brief asked those cited to review the parts of the report where their work was used, and we collectively found 100+ misleading or false statements: interactive.carbonbr...

Awesome thread!

NEW: i spoke to nine (!) scientists across several disciplines whose work was cited in the new Department of Energy report that downplays the severity of climate change. all of them say their work was misrepresented, cherry picked, and/or lacked context —

Every time I open LinkedIn, someone from a science agency shares an unplanned (forced) early retirement or RIF. Lately it’s NASA & EPA. In spring, NOAA. I think people have no idea how deep this loss really is. I don’t know what rebuilding federal science looks like, but it won’t be simple or quick.

Discontinuing the Mauna Loa observing program would be a tragedy. The epitome of sticking your head in the sand. www.nytimes.com/2025/07/17/c... See the compelling case for maintaining the Keeling Curve from Keeling himself: www.youtube.com/live/CcWR6Cd...

This is, to me, the defining dyamic of everything the last six months. Any game theory notion of deterrence or the shoe being on the other foot ever is entirely gone. Either 1) They don't think they'll ever lose power again or 2) they're confident Democrats won't ever do the same things back to them

Under climate change, the polar regions warm *faster* than the rest of the world ("polar amplification", PA). But, is this always the case? In this preprint (with Tim Merlis) we studied the 'state-dependence' of PA—feedback welcomed! :) andrewilwilliams.github.io/papers/pa_widerange_main.pdf

So, what is a “rescissions” bill?

“Vibe physics” is me and my astrophysics friends discussing things at the pub, sometimes leading to actual breakthroughs. Prompting a large language model that can’t even get basic maths correct is not the same.

Just one chart from the @metoffice.gov.uk State of the UK climate report published today. We get used to focusing on the record highs and how 35C has gone from being rare to routine. But just look at all those summers which never got to 30C even in my lifetime. It’s a different UK now.

New York City received 2.07" (52.6 mm) of #rain in the past hour. That is the 4th biggest hourly rainfall on record for July. Moreover, it is the biggest hourly rainfall since an all-time record 3.15" (80.0 mm) of rain fell on September 1, 2021. #nywx

This is so much worse than just the headline (which is already bad). SCOTUS just gave the president the power to dismantle any department that Congress created…

Oh, Mann! ;)

The Trump administration has proposed devastating cuts to NOAA, including the potential closure of multiple cooperative institutes in Colorado. Every American should oppose this reckless proposal — and we are building a coalition of lawmakers to do everything we can to defeat it. 👇🏾 👇🏾 👇🏾

When Earth warms, the total rainfall increases. Here we show that this change in rainfall is also sensitive to the *pattern* of warming, build a theory to explain why, and use it to explain why rainfall increases more in uniform warming exps than abrupt-4xCO2 :) essopenarchive.org/doi/full/10....

If people think American scientists are somehow going to land in Europe, I've got news for you about the difference between millions and billions. www.nature.com/articles/d41...

Nice local news piece covering one of the events on our recent Climate Up Close tour in Nebraska! The tour was incredible, and it is clear that people in the Midwest are hungry for climate knowledge! (I don't have media training and was just put in front of the camera, so be kind)

We are living in a time of bullshit. From AI slop to saturated advertising to institutions too afraid of their own shadow to ever commit to a value or principle, people want connections to authenticity and politicians who seem ‘real’. #CAMRI

🧪 Russ Vought, a Project 2025 architect, is currently withholding $2.5 billion from NSF's budget for this year. This move is: -Illegally secretive -Unusual and suspect -Disrupts science -Subverts Congress It's also urgent because the *fiscal* year ends Sept 30 (call your rep). 🧵 Let's unpack...

More science data loss with potential impact on hurricane season: processing and delivery of Special Sensor Microwave Imager/Sounder ends by 30 Jun. SSMIS is used by forecasters to assess tropical storm location, cloud structure, and intensity. It’ll lead to 📉 in monitoring ability & forecast skill.

Both science and universities in the US are in the process of being devastated by our current president and his administration. I felt compelled to use my little platform to say something about this. So instead of my uncle, I'm talking about this instead, this week on the podcast. bit.ly/3Ta2FIE

The review process has gotten ridiculous. 2 papers in review that took a year(!) to get second round of reviews back to us My working theory is that the number of submissions has gone up, esp from outside US (e.g. China, Europe) but editors have not expanded reviewer pool to include these authors

they’ve gone from “clearly uniformed” to “partially uniformed” to “in no way identifiable” in like three weeks
