California Gov. Jerry Brown (D) took on protesters at a climate talk on Saturday, saying "let's put you in the ground" in response to the continual disruptions targeting Brown's environmental stances.

Protesters at the "America's Pledge" talk in Germany, an event in support of the Paris climate agreement that the United States withdrew from this summer, called for reduced oil drilling during Brown's talk. According to the Sacramento Bee, protesters chanted, "carbon trading is no solution,” in reference to the cap-and-trade system, as well as “poisoned wastewater” and “keep it in the ground.”

“I agree with you, ‘in the ground,’ ” Brown said amid the protests. “Let’s put you in the ground so we can get on with the show here."

“Anyway,” he later said, “This is very California. Thank you for coming. Actually, that’s very mild.”

At one point in the speech supporters of Brown chanted against the protesters, resulting in chants of "we're still in," "Trump's still out," and "We love Brown."

Environmentalists have previously criticized Brown over his advocacy for hydraulic fracturing, a fossil fuel extraction technique, which some environmentalists see as contradictory to his strong stance on mitigating climate change through the reduction of fossil fuel use.

California led the charge of a coalition of individual states rebelling against the unpopular decision to withdraw from the Paris Agreement, vowing to maintain the pact's environmental goals independently from the federal government.

“Most of these critics ride around in cars and fly in airplanes, so what we have to do is get the end goal in sight," Brown later said of the protesters. The governor is on an 11-day trip through four countries.
