How Will California’s Climate Ambitions Reshape Food and Agriculture?

At the outset of last month’s Global Climate Action Summit in San Francisco—even before the release this week of a dire U.N. climate report—California Governor Jerry Brown made a bold announcement, setting a target for the state—the world’s fifth-largest economy—to achieve net zero emissions by 2045.

California has taken on a heightened role in climate diplomacy since the United States’ 2017 withdrawal from the Paris Climate Agreement. But even insiders were stunned by Brown’s wide-ranging executive order. Ecologist and incoming executive director of climate advocacy organization Project Drawdown Jonathan Foley hailed the move as “the most ambitious serious climate commitment ever made on earth.”

Brown has signed a number of bills spelling out how California might achieve its goal, including SB100, which commits the state to 100 percent carbon-free electricity by 2045, as well as a series of bills intended to increase the adoption of electric vehicles. But missing from the flurry of legislation are concrete plans for the future of food and agriculture.

These very hungry microbes devour a powerful pollutant

PETALUMA, Calif. — The cows had to be deterred from messing with the
experiment.

Researchers from a Bay Area technology company had come to the sprawling
dairy farm north of San Francisco to test an emerging solution to planetwarming emissions: microscopic pink organisms that eat methane, a potent
greenhouse gas.

Kenny Correia, 35, of Correia Family Dairy, watched the team from Windfall Bio
working near the lagoons used to store manure from the farm’s several hundred
cows. The researchers erected a futuristic system of vats, pipes, tubes and shiny
metal supports. Then, when everything was assembled, they poured pink liquid
into one of the vats. “They were looking like mad scientists out there,” Correia
recounted.

He acknowledged initially thinking it was a “crazy idea” to integrate an outdoor
laboratory into a working farm. There was the potential for the cows to “be all
over it — licking it, pulling out wires and scratching on it,” he said.
But livestock farms are a significant source of methane emissions, and Windfall
wanted to see how much the microbes could help.
