Teen climate agitator Greta Thunberg is looking to hitch another low-carbon ride across the Atlantic — after protests in Chile forced a venue change for an environmental summit.

“It turns out I’ve traveled half around the world, the wrong way,” the Swedish activist tweeted Friday, after officials announced the COP25 climate summit will be held in Madrid next month, instead of in Santiago, Chile, as planned.

“Now I need to find a way to cross the Atlantic in November,” Thunberg added. “If anyone could help me find transport I would be so grateful.”

Thunberg, 16, excoriated world leaders at the United Nations General Assembly in September for their inability to stop carbon emissions.

“How dare you? You have stolen my dreams and my childhood with your empty words,” she said.

To get to New York for the meeting, Thunberg — who shuns airplanes and gas-powered vehicles — took a two-week voyage across the Atlantic in a zero-emissions sailboat.

She has been traveling across North America — on trains and in electric cars — ever since, on a slow journey to Santiago for the planned climate meeting.

A group of 36 climate protesters learned of the summit’s cancellation Thursday, four weeks into their arduous ocean voyage from Amsterdam, CNN reported.
