Also, I'd love to know how two different stories -- each written by three reporters, with no overlap in the authors -- managed to find Jolene Riessen and make her the stand-in for apolitical Iowa farmers.

There are only two explanations for the NYT's habit of presenting GOP operatives and donors as true swing voters: 1. Their reporters and editors are somehow incapable of running a simple Google searches, showing just a staggering level of journalistic incompetence 2. They want to the GOP to win

I'll be participating in a #ScienceUnderSiege panel at the #RawScience Film Festival at Lincoln Center in NYC, Friday Nov 6 at 6pm. Come out and join us! www.rawsciencefilmfestival.com/2026-festiva...

What is that vehicle setting a distance driving record on Mars? An EV, of course. They’re reliable on Mars, the moon, and right here on Earth. www.nytimes.com/2026/10/12/s...

Must-watch via @yellowdotstudios.bsky.social And yes, I'm one of those climate scientist "fat cats" they refer to 😂

This is literally right out of the Lord of the Rings

Countries are going to have to start banning these companies. Their leaders think they have a chance at becoming global oligarchs and they're shooting their shot. Cut them down to size.

It’s late October. People are voting right now. If you cannot deliver a convincing, full throated endorsement of the Democratic nominee in the potentially deciding race for the Senate, stay the fuck off television

House Judiciary Democrats have just released a 50-page report that pulls together years of assault allegations against Trump and his reported connections to Jeffrey Epstein. The report calls for a special counsel to investigate Trump's ties to Epstein.

the pleasure is mine folks--thanks for all you do!

Absent deployment of artificial carbon uptake (but we can’t bank on that—and it won’t be deployable at scale for decades anyway, so it is irrelevant to the task of near-term decarbonization)

Well this is a “choice election” after all

The planet’s surface will keep warming until carbon emissions cease. It’s up to us.

Scientists must join larger pro-democracy and people's movements Our training may not have prepared us for such work, but we can no longer sit in the safety of our labs and expect the world to get better @michaelemann.bsky.social @peterhotezmdphd.bsky.social www.thelancet.com/journals/lan...

It's the same PEOPLE actually: rogerpielkejr.substack.com/p/a-covid-19...

Attribution is where the rubber really hits the road. So the denialists (led by fossil fuel tools like Roger Pielke Jr) have focused their attacks on it. Writing about it in my forthcoming book “Back to Earth”

Yes, professional science deniers like Pielke Jr, as Peter Hotez and I discuss in "Science Under Siege", are typically equal opportunity promoter of ideologically-motivated antiscience:

Prof. @michaelemann.bsky.social is quoted in ABC News on UN projections which show a hotter world than experts projected last year. Mann says these temperature increases would shave about $1.2 trillion from the global economy. @upenn.edu

Honestly, I now totally get the whole "YMCA" thing...

“Worse than climategate”!!! It’s hard for any “scandal” not to be worse than a debunked email hacking and disinfo campaign relying on quote mining scientists' emails to make it seem like they were lying about matters they weren't 🙄 No pattern of skewed presentation here. @michaelemann.bsky.social

Trump's closing argument: Make everything white!

What does Jared Kushner actually do with all that Saudi oil-dictator cash? After Trump hyped a massive gas plant and Amazon data center in tiny Homer City, Pa., Kushner and his Arab money bought into the project It's a climate disaster My new column www.inquirer.com/opinion/hype...

yes, but that was factored into the calculations long ago.
