Like all Peters' papers this one's a little mind-blowing. Where in Precambrian, volcanic CO2-turned-limestone kept piling up on seafloor & getting recycled in subduction zones, in Phanerozoic it started piling up on continental crust, leaving deep sea starved of carbonate, worsening the end-Permian
PreꞒ/Ꞓ fundamental change in sedimentation:
"... relatively abrupt shift in the principal locus of CaCO3 burial, from short-lived oceanic crust during much of the Proterozoic to longer-surviving continental crust in the early Paleozoic"

There is, in fact, plenty of money sloshing around that could do things like build a nationwide macrogrid or lots of high-speed rail

Pairs well with news of the 1st private space telescope, a return to the era of Licks and Lowells. Turn out we've lived in a brief window where cosmic exploration was driven by the curiosity of citizens in a democracy, not rich eccentrics, insecure sovereigns, industries, or navies. It was awesome.

I have to say, I’m really not thrilled that my country is devolving into a lawless gangster state abroad, and at home, one officially dead set on destroying science, art, and any shared feeling of common humanity

Earth, I can't emphasize enough, is a very special place
New paper alert!

tl;dr: the seafloor of Europa is probably tectonically inert, meaning little to no active fracturing that could expose fresh rock to seawater.

Without such water–rock reactions the prospect for there being life within Europa just took a big hit.

Made a pilgrimage to 2 ghosts of sea level past & future in Florida, from last time global temp was similar to today 120,000 years ago: an outcrop of oolite in Miami from when it was a sandy shoal under the waves, and in Windley Key a fossil coral reef that now ominously sits 20 feet above sea level

"If we are going to go all in on a fossil fuel future in the U.S., it probably would be good to check if we have the fossil fuels to do that." Geology strikes back
Good morning. How about 2000 words about the state of the US oil industry?

"Hamm admitted the Bakken is 'tapped out.' The reason he is buying shale assets in other countries is because the reality is that the U.S. oil industry is tapped out."
Lessons from the Bakken
The New York Times recently profiled Harold Hamm, Continental CEO Resources chairman emeritus and noted how Hamm is advising Trump to go all in on fossil fuels. This should surprise no one as Harold H...

I've tried and failed a couple times to write a post explaining how serious this would be. NCAR is globally essential to our climate change response. This can't just be replaced. Every scientist in the world will be doing climate research with one hand tied behind their back for at least a decade
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.
