In Texas, the State is removing climate change courses from the core curriculum. They have decided that climate change is just too dangerous to teach the students. This is indoctrination. I wrote an oped about it in the SA Express-News. Gift link: www.expressnews.com/opinion/comm...

The literature about changes in nor’easters due to climate change is clear about two things: 1) more intense precipitation due to a warmer atmosphere, and 2) more extensive coastal flooding due to higher sea levels

The total number of tropical cyclones on Earth is pretty constant — around 80 per year — so if there are few in the Atlantic, we would expect to see a lot in other basins.

Letting Hader throw so many pitches was a risk that didn't pay off. Hader obviously not available today and I wonder if he'll be available tomorrow. Unless the Astros or Rangers go 4-0, the winner of the AL West in 2026 will set a record for worst record to win a division.

Given the outrageous, dangerous, and outright false statements made about how the polio (and other) vaccine was a "fraud" (at the Children's Health Defense conference), here's a reminder of what a massive success it was. RFK Jr. & his minions must be stopped from destroying the US healthcare system.

I got a question from @afreedma.bsky.social about what the models show. Here's global average precipitable water for Aug. from CMIP6 models. PWAT increases more in the models than in the observations. The disagreement appears to be linked to a lack of increase in the observations prior to 2000.

A side-by-side comparison of three distinct headlines and subheads published by *The New York Times* for the same article topic, tracking changes in phrasing:

* **First Version (Left):** Headline reads *"More Civics, Less Sociology: How Politics Is Shaping College Requirements"* in bold italic text, accompanied by the subhead: *"Politics and other factors are causing universities to reconsider what classes are core requirements. In some places, civics and classics are replacing climate change and sociology."*
* **Second Version (Middle):** Headline reads *"What Should Be Essential Learning at College? It's Getting More Political."* with identical subhead text below.
* **Third Version (Right):** Headline reads *"How Conservatives Are Changing College Requirements"* with a slightly tweaked subhead reading: *"Politics and other factors are causing universities to reconsider what classes are part of the core required for graduation. In some places, civics and classics are replacing climate change and sociology."*

And yes, it would be worse if a transphobic Dem wins. None of the anti trans policies would be undone and then we get a model for other centrists to abandon trans people.

holy crap it's expensive to go to the AGU meeting. hotels in San Francisco are well above $300/night after you add tax; meeting registration is > $800. then add in $600 for airfare. just this is nearly $3K. and it doesn't include a lot of ancillary expenses like parking at the airport, etc.
