If the world wants an American climate leader, the California governor is happy to play the part, even if his country isn’t quite ready to follow.

BELÉM, Brazil — Gavin Newsom can’t get out of a meeting or a talk at the international climate talks here without being swarmed by reporters and diplomats eager for a quote, a handshake, a photo.

On a tour Tuesday of a cultural center with Gov. Helder Barbalho, the leader of the Brazilian state hosting the talks, a passerby recognized them both. “There’s the governor,” he exclaimed. “And there’s the California governor.” Later in the day, as Newsom rode up an escalator packed with reporters and international officials on his way to deliver a speech, a bystander shouted: “The escalator’s not broken for you!” — a dig at President Donald Trump, who once had an escalator malfunction on him at the United Nations.

Newsom grinned wide: “Oh, I like that.”

The adulation was gold for a governor with presidential aspirations as he steps into a power vacuum. The Trump administration is trying to dismantle climate policies both at home and abroad, and other likely Democratic presidential contenders are absent from the United Nations climate talks. Seeing a chance to plant his green flag on an international stage, Newsom is embracing the role of climate champion as his own party backs away at home and the politics of the issue shift rightward.
