A 19-year-old German YouTuber is being dubbed the “anti-Greta.”

A US think tank with ties to the Trump administration has tapped Naomi Seibt, 19, who touts “climate realism” over “climate alarmism,” to represent its views, according to the Washington Post.

“Naomi Seibt vs. Greta Thunberg: whom should we trust?” the Illinois-based conservative and libertarian Heartland Institute asked in a video, referring to the 17-year-old Swedish climate activist.

James Taylor, director of the Arthur B. Robinson Center for Climate and Environmental Policy at the institute, called Seibt a “fantastic voice for free markets and for climate realism,” the newspaper reported.

During the UN climate conference in Madrid in December, Heartland headlined Seibt at its forum, where Taylor described her as its “star.”

And in January, the institute hired her to represent its climate skepticism campaign about global warming, according to the news outlet.

Thunberg, who was named Time magazine’s “Person of the Year” last year, has excoriated world leaders for their failure to stop carbon emissions.

“I want you to panic,” she said at the World Economic Forum in Switzerland last year. “I want you to feel the fear I feel every day. And then I want you to act.”

But Seibt says in a video posted on Heartland’s website: “I don’t want you to panic. I want you to think.”

She has also invoked Thunberg’s famous line, saying, “To the media, I have a few last words: How dare you?” — but has disavowed the “anti-Greta” moniker.

“The reason I don’t like the term ‘anti-Greta’ is that it suggests I myself am an indoctrinated puppet, I guess, for the other side,” she says in a video titled “Naomi Seibt vs. Greta Thunberg: Whom Should We Trust?”

“It is important that we keep questioning the narrative that’s out there instead of promoting it,” Seibt said. “These days, climate change science really isn’t a science at all.”

She told Insider she’s “not this evil opposite of Greta — she might be a really nice girl and I would love to talk to her someday.”

Seibt, who is a former “climate alarmist” herself, said that watching people joining Thunberg-inspired “Fridays For Future” helped spark her opposition to climate change activism.

“I get chills when I see those young people, especially at Fridays for Future. They are screaming and shouting and they’re generally terrified,” she told the Washington Post. “They don’t want the world to end.”

Seibt, who will appear at the Conservative Political Action Conference, or CPAC, this week, said she does not dispute that the Earth is being warmed by greenhouse gas emissions — but that their impact has been overstated by many scientists and activists.

“I don’t want to get people to stop believing in man-made climate change, not at all,” she told the paper. “Are man-made CO2 emissions having that much impact on the climate? I think that’s ridiculous to believe.”

Through her reps, Thunberg declined to comment to the Washington Post.
