My daughter made her own song for today’s #NoKings. This is her third protest.

The Farm Bureau estimates that a year-round increase from E10 to E15 (15% ethanol blend in gasoline) would increase US corn demand by 2.4 billion bushels a year.

Latest yields per USDA are 188.8 bushels/acre, so growing it requires another 12.7 million acres. That’s about half the size of Indiana.

The study (which I co-authored) looks at the energy content, (or calories) of 50 crops grown globally, which represent 98% of all calories produced on croplands. It does not include dried hay, crop residues, leaves etc.

Two global maps, side-by-side. The map on the left shows calorie production on croplands in shades of blue (in million calories per hectare). The global map on the right shows the percentage of calories production available as food. In the midwest of the U.S. there is high crop calorie production but a small fraction is available as food. in India and countries in central and southern Africa, much of the calorie production is used for food.

In the U.S., out of every 10 calories grown on croplands, less than 2 of those calories (17%) are grown for food.

The rest? Animal feed and biofuels.

Only half of calories produced on croplands are available for human consumption, study finds Study: 1/2 of the calories produced on croplands are unavailable for human consumption

This is one of the most important issues with the global food system, yet it is often ignored.

Put simply, we don't actually grow much *food* in our farms around the world. Instead, we grow grossly inefficient animal feed and biofuels.

Yes, @paul-west.bsky.social and @jamesgerber.bsky.social bravely took this on with the new FAO data, with me on backup vocals. Thanks for the shoutout! 🎤

Congrats to the Project Drawdown team. Looks like a useful update of one of my fav papers, @enviroem.bsky.social et al 2013.

Feeding more crops to people & fewer to animals & vehicles would make it way easier to feed 10B people and end deforestation, stabilize the climate, cut water pollution etc.

I just resigned from NASA. It breaks my heart to leave, but I’ve become convinced the best path forward is to do the best science I can, and that can’t be here anymore. I’m still in love with the promise of those four magic letters. Ad astra per aspera, and remember: Earth is the only good planet.

Climate solutions like protecting peatlands, improving rice production, and better nutrient management will have a real impact on emissions, without reducing yields. A new study published in @nature.com was co-authored by three Drawdown Scientists.

Btw this shouldn’t be a direct quote but captures Jefferson’s writing in Declaration of Independence: "...when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism […] it is their duty, to throw off such Government..."

Q: "Do you think that Donald Trump should be deposed by this Committee?"

Hillary Clinton: "Absolutely."

"Donald Trump has been held civilly liable for sexual assault by a jury of his peers … That is behavior that fits a pattern if one were looking for a pattern."

On top of everything else, oil and gas prices are going to spike because of Trump’s war in Iran.

But guess what doesn’t get disrupted by wars?

Poore and Nemecek's analysis is based on 160-some studies. The results depend heavily on where the cocoa is sourced... (so if Turkey has a source with less land use change, good for them!) There is a lot of deforestation happening for cocoa in West Africa unfortunately.

Reducing food’s environmental impacts through producers and consumers Food producer heterogeneity on a global level creates mitigation opportunities with respect to environmental damage caused by food production.

Sadly, these results may be limited to "the emerging chocolate market in Turkey." Acc. to a more extensive lit. review of GHGs of food products, which incl. a more global perspective on deforestation for cocoa, dark chocolate (70%) contributes ~48% more GHGs than milk. See doi.org/10.1126/scie...

Sam Alito has an oil money problem 30 percent of Alito’s individual stock portfolio is directly tied to fossil fuels.

The Supreme Court has decided to hear a major climate case against fossil fuel companies

Alito has not recused himself, despite owning nearly $200,000 in fossil fuel stocks—including in Phillips 66 and ConocoPhillips, which are being sued in cases that would be directly affected by a SCOTUS ruling

Epstein Files Are Missing Records About Woman Who Made Claim Against Trump

We seem to be nearing the heart of the story, and a lot will depend on the nerve of the journalists--NPR, the NYT, etc--to stay on this story relentlessly. Will they give it the same kind of coverage they gave Biden's age--i.e., full bore, around the clock, 50 opeds?
