Using genetic markers, wind simulations, satellite imagery, property records and more, we found that the virus could’ve been airborne.

We saw it with big tobacco, we saw it with the fossil fuels industry. When their own internal research showed the harm from their product, the defunded the research and attacked independent researchers coming to the very same conclusions.

Was there any coverage of the recent record warmth in both the Arctic and Antarctic? Multiple global datasets now confirm these records, and I think it's really quite striking.

Here's some very quick plots showing NOAAGlobalTempv6 data from October too. And see my earlier posts.

A line graph shows the time series of Arctic mean surface temperature anomalies for each October from 1850 through 2025. There is a long-term increasing trend and large year-to-year variability. The mean surface temperature anomaly in October 2025 was 3.78°C for this region. Anomalies are computed relative to a 1910-2000 climate baseline. All data is from NOAA/NESDIS/NCEI NOAAGlobalTemp v6.0.0 on this graphic.

Breaking News: Robert F. Kennedy Jr. said he personally instructed the CDC to abandon its position that vaccines do not cause autism. The move underscores his determination to challenge scientific orthodoxy — in this case, that vaccines save lives — and bend the health department to his will.

This Atlantic piece significantly underestimates the magnitude of discontinuity around us.

It treats as futures to be avoided realities that are already unfolding now.

I suspect largely because it absolutely sucks to acknowledge we lost the Orderly Transition.

How awful. This is outright health disinformation, lying to the American people. Not only is there massive evidence showing no link between vaccines & autism, there’s not even a plausible mechanism based on what we’ve learned about the genetics of autism, some environmental exposures in pregnancy

Sheryl Gay Stolberg @sherylnyt.bsky.social · 5d

HEADS UP: CDC website now officially asserts that vaccines may cause autism.“Studies supporting a link have been ignored by health authorities.” Also says the “vaccines do not cause autism” header remains b/c of an agreement with Cassidy.

"When the planet heats up beyond 1.5 degrees, the impacts don't get just slightly worse. Scientists warn that massive, self-reinforcing changes could be set off, having devastating impacts around the world.

Such changes are sometimes called climate tipping points..."

As the Earth continues to heat up, it will trigger massive, self-reinforcing changes. Scientists say ice sheets could collapse, permafrost could melt and coral reefs could disappear. Each of these tipping points will have dramatic impacts on humanity.
