"Dems have got to be prepared to inherit a munitions-and-readiness hole that is going to be expensive to fill, but which will need to be filled." No? Not necessarily? And not without attaching massive audits and institutional reforms?

All the projections I've ever worked with predicted an acceleration in the rate of global warming if we continued to increase our emissions. The fact that so many people are shocked about this honestly surprises me. I guess no one ever reads things like the IPCC or National Climate Assessment 🤷‍♀️

A figure I made for NCA4 about 10 years ago. The world was tracking the RCP8.5 scenario equivalent emissions through about 2020, and that's the temperature change we're seeing today.

You can/should read Emily Wilson's latest take on the Odyssey, but I'm logging on to convey my hairdresser's reaction. She was AGHAST that Nolan, with his million $ budget, gave Matt Damon ONLY 6 hair extensions. As a result, his hair did not blow around properly, & that ruined the film for her.

The cool thing is that this eye leaves behind skeletal evidence. Turns out, if we measure this feature in a large selection of fossils, we might be able to learn a few things about the evolution of thermoregulation...and maybe a few other interesting aspects of animal biology.

New research out today! Some animals have three eyes?! This eye isn't for "seeing" per se, but it's connected to a part of the brain responsible for regulating body temperature. So if you see a lizard basking out in the sun to get warm, oftentimes this eye plays a central role. But there's more...

Images like this make me sad. No incorporation of the mantle whatsoever. Volatile flux into the mantle is *huge* and there's no guarantee all of it gets returned via volcanism over the lifetime of a subduction zone. We're pretty sure whether the upper mantle is reduced or oxidized matters, too.

A figure from an atmospheric CO2 and O2 through geologic time paper. Volcanoes are shown as sources for carbon and material that affects atmospheric oxygen indirectly, everything else is an erosional or sedimentary process. There is no return of anything to the mantle.

Worth emphasizing: *every* good geochemical or geochronologic estimator has a controversial history. That is a big part of what makes it *good*. The arguments are the traces of us figuring out the chemistry & physics of the estimator, & usually mean we can do more with it than originally thought.

The decisive failure of GOP referenda in Kansas Amendment 1 and Missouri Amendment 4 yesterday is yet another reminder of something I've been saying for a while: Voters, even Republican voters, now regularly despise and repudiate GOP attempts to use them to destroy democracy.
