Dear climate visionaries: Resist France’s allure

Back in February, when France’s then-presidential candidate Emmanuel Macron thumbed his nose at President Donald Trump and invited jaded U.S. scientists and inventors to come build a sustainable future in France, I applauded and played along.

“[L]et’s face it,” I wrote. “France is a tough sell. The food is irritatingly fresh, the architecture tends to distract people from their cellphones, and the high-speed rail lines get in the way of SUVs.”

But now that Macron is president and has backed up his words with substance, setting up a program to bring American climate visionaries to France, it’s no longer funny. If you’re an entrepreneur, scientist, or engineer disillusioned with Trump’s America and tempted by this offer, please don’t go. It’s a terrible idea. Do you hear me, Katharine Hayhoe?

Mais porquoi? you say, after thumbing through your French phrasebook. Because the United States, the world’s second-biggest polluter, is a much more pernicious driver of climate change than France, the 18th. We need you here. The world needs you here. The future needs you here.

OK, I’ll cop to getting a little carried away. We should give Macron his due. He’s offering a four-year grant to people from anywhere in the world, so they can come work on climate change projects in France. That’s great! Science, technologies, and companies created in France won’t be constrained by French borders. We’ll all benefit. And it’s just for four years, the nominal length of Trump’s (first) term. But c’mon, be real: Nobody goes to France to live for just four years.

This screenshot from Macron’s new website, titled “Make Our Planet Great Again” seems to confirm my concerns that France wants to keep our smarties forever.

I’m worried about a brain drain. We can’t afford to lose the political heft of scientists as communicators and U.S. citizens. The United States needs people who weigh evidence and allow that evidence to change their minds. We need men and women like this of all political stripes living in American towns, talking to their American friends, going to American churches, and helping to make this country sane again. If we all sort ourselves into like-minded factions, and a chunk of the rational faction moves to France, we’re screwed. We really can’t afford to lose Neil DeGrasse Tyson to the Riviera. James Hansen, Pam Ronald … stay!

Here’s how no-slaughter meat goes mainstream.

In a new report, Grist 50-er Liz Specht identifies the obstacles that prevent earth-friendly meat from taking over the world. If meat stopped coming from cows and was instead grown in the lab, she argues, it would slash meat production’s environmental footprint.

So, Specht and her colleagues at the Good Food Institute hope to midwife the birth of a new clean-meat industry. To get there, we’d need some crucial innovations. Here’s a taste:

Better bioreactors: Bioreactors are big tanks that slowly stir meat cells until they multiply into something burger sized. They already exist, but we need the a new generation that do a better job at filtering out waste, adding just the right nutrients, and recycling the fluid that the cells grow in.

Scaffolding: If you want nice tender meat, instead of a soup of cells, you need a scaffold — a sort of artificial bone — for meat cells to cling to so they can take shape. People are experimenting with spun fiber, 3D-printed grids, and gels that cue cells to form “the segmented flakiness of a fish filet or the marbling found in a steak.”

Growth fluid: At the moment, meat cells are mostly raised in fluid taken from cattle embryos. But there won’t be enough embryonic fluid if reactor meat replaces the livestock industry. So scientists are working to mass produce fluid that nurture’s developing cells.

Democrats are proposing a bill to keep farm laborers from being deported.

Kait Parker grew up the daughter of a math teacher and a storm-spotting firefighter, which likely explains her spitfire approach to explaining atmospheric science. Last year, when Breitbart attempted to disprove climate change by misleadingly poaching only a portion of her Weather Channel segment on La Niña, Parker fired back. She called out the alt-right site for its dubious methods in an online video. “Next time you’re thinking about publishing a cherry-picked article, try consulting a scientist first,” she zinged. The response brought a wave of social-media support and shout-outs from mainstream media like Elle.

Parker is currently doubling down on reaching her fellow millennials, producing and hosting shows on digital-only outlets like the Weather Channel app and Snapchat. Her YouTube series, “Science Is Real,” examines the consequences of a warming planet. And later this spring she’ll launch “The United States of Climate Change,” a massive 50-part series that will chart climate impacts in every state through short videos, written pieces, and even graphic novels.

“If 97 doctors told you you were dying of cancer, would you believe them, or the three that didn’t?” she says of climate change. “The more lives I can help save and communicate the risk, the better.”


Meet all the fixers on this year’s Grist 50.
