What's this "weave" crap? He rambles; he's incoherent; his mind can't focus. Stop trying to excuse this as some intentional speaking strategy. Any other politician would be excoriated for his inability to string together coherent thoughts.

San Diego's problem isn't an Iranian attack. It's a climate-change-enhanced hurricane.

Powering data centers on nuclear? That's a tough sell in Utah's coal country.
To power two new data centers, Carbon County is getting a massive gas plant and 456 small nuclear reactors. Locals are pushing back.

Check out this amazing story (to me, anyway) of a 1000-mile-long cloud that consistently forms and disappears on #Mars. As a climate and water scientist, this fascinates me. www.livescience.com/space/mars/1...
livescience.com
1,000-mile-long cloud that forms and vanishes on Mars every day obeys 'exotic physics' never seen on Earth
New simulations suggest that the perplexing Arsia Mons Elongated Cloud (AMEC) repeatedly emerges in the Red Planet's skies thanks to a never-before-seen meteorological process.

There's a whole comms team at the White House whose sole job is to say "That's not what he said" or "That's not what he meant" every time Trump speaks.

I'm not weighing in on how to interpret the twisted comments Trump just made. But realize how dangerous it is to have a president whose statements and syntax are incomprehensible, confusing, and confused.

The timing is just a coincidence, but I put the finishing touches on three accepted peer-reviewed journal articles today, one of which has been in the works for 18 months. Now I need a nap. Also, there's a Townsend's Warbler in my backyard that needs to be watched. #birds

This is why I think it's good that Trump plans to spend the next month campaigning for Republicans: every time he opens his mouth, something epically stupid, racist, sexist, or incoherent comes out. His support for candidates (or sports teams, or anything) is now toxic.

Lol. Xi Jinping & Donald Trump agreed for China to buy 10m tonnes of US coal in 2027 and 2028. But in 2024, we exported 12m tonnes to China. When Trump put tariffs on China it dropped to zero. So Trump breaks something and then claims success when he fixes it. www.carbonbrief.org/china-briefi...
