There have been increasingly shrill accusations against the EU over its digital legislation, based on accusations of "censorship" by defenders of "free speech" -- including, so it appears, the right to peddle an AI app that seemingly produces child sexual abuse material (CSAM). 1/9

While mitigation efforts exist, the broader evidence doesn’t support the idea that beef is a climate solution. A 2021 review of 292 beef systems found only 2% achieved net-zero emissions. Read the full review: science.feedback.org/review/impac...

Viral claims that cows and beef are climate solutions ignore the impacts of cattle farms

At first glance, the idea has intuitive appeal: cows eat grass, grass absorbs CO₂. But this overlooks key emissions from cattle, especially methane, a short-lived but potent greenhouse gas Methane from cattle belching outweighs the CO₂ absorbed by pasture plants in most cases.

We’ve seen recurring claims on social media and in TV segments that cattle are good for the climate, or even 'carbon-negative'. These claims often misrepresent the research they cite or rely on narrow case studies. science.feedback.org/review/impac...

Additionally, it appears that all of EPA's previously extensive "indicators of climate change" pages have been scrubbed entirely. The pages no longer exist; there are numerous dead links on the current/live EPA site, and no indication they have been moved to a new URL.

This can be confirmed using the Wayback Machine's last snapshot (from Oct 8, 2025). At some point between Oct 8 & Dec 8, major changes were made to this and other EPA climate change content. Information has either been removed completely or "adjusted" to emphasize natural causes.

The study also didn’t account for healthcare-seeking behaviour.
 Vaccinated people tend to get tested more often → more diagnoses → not necessarily more illness. Bottom line:
More recorded cases isn't necessarily a sign of weaker immune system.

We also consulted Prof. Helen Petousis-Harris, who highlighted major limitations. Yes, the study found more common colds in people with 4+ doses, but that same group had lower rates of flu-like illness and pertussis. That pattern doesn’t fit the claim of “weakened immunity”.

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.

Nice article about NASEM review of the endangerment finding by @insideclimatenews.org National Academies Will Review Endangerment Finding Science insideclimatenews.org/news/0708202...
Andrew Dessler, director of the Texas Center for Extreme Weather at Texas A&M University, said the new controversy that the Trump administration had stirred around climate science was a fitting subject for a fast-track effort by the National Academies.

“The National Academies [were] established exactly to do things like this—to answer questions of scientific importance for the government,” he said. “This is what the DOE should have done all along, rather than hire five people who represent a tiny minority of the scientific community and have views that virtually nobody else agrees with.”
