Van Gogh distrusted varnish. He left his paintings matte, which he considered closer to the natural appearance of the paint and more aligned with his artistic vision.

Regarding the insurance industry, I'm not an expert, but saying it's "only a stress test" could be a bit misleading if those stress tests are used in rate setting. Jessica Weinkle and Roger Pielke Jr. allege this is the case (again, I'm not an expert). rogerpielkejr.substack.com/p/the-climat...

“The most extreme scenarios have met an overdue but welcome demise,” Roger Pielke Jr. writes. “The question now is whether the rest of the world will follow.”

How Climate Science Lost Its Way on Scenarios A summary of our 2021 deep dive on what went wrong rogerpielkejr.substack.com/p/how-climat...

My colleague @kschake.bsky.social: "Without bases in Europe, US power projection becomes much more difficult and costly. Troops stationed overseas are not a gift to allied countries; they are enablers of America’s global military power." www.aei.org/foreign-and-... #policysky

"The committee responsible for official IPCC scenarios... declared the high-end scenarios... to be implausible. These scenarios have dominated climate research, headlines, and policy for the better part of two decades." by @thehonestbroker.bsky.social www.realclearscience.com/2026/05/11/b...

Just a quick Austria-appreciation post. It's a pretty country with great schnitzel and even better desserts.

Good work, Roger. In the first draft of the SPM of AR6 WGI, a numerical majority of the authors were from western Europe (3% of the global population). After it had been drafted and the main points decided upon, they opened the doors to new authors, which made it look inclusive.

Some interesting statistics from @thehonestbroker.bsky.social, & this is after expanding the steering committee to include more from the Global South! It would be interesting to compare to CMIP6 ScenarioMIP gmd.copernicus.org/articles/9/3... and Moss et al www.nature.com/articles/nat... 1/

Aid to Ukraine from 2022-2026 was a rounding error. We used more in the first two weeks of the Iran war than we provided in the 4 years of aid to Ukraine.
