Naomi Seibt

In a 19 February 2020 interview with Die Weltwoche, Seibt said that she became interested in politics in 2015, when she was 14 years old, and began to attend political events with her mother. At that time, she was critical of the Christian Democratic Union of Germany (CDU). Seibt lives in the suburb of Münster, North Rhine-Westphalia, Germany, with her sister and their mother, a lawyer, who according to The Guardian, "has represented politicians" from the far-right Alternative für Deutschland (AfD) party.

A 28 February 2020 article in The Guardian said that Seibt was inspired by the alt-right, white nationalist Stefan Molyneux, after being introduced to his blogs. She has also been accused of both white nationalism and antisemitism due to her support for some on the Alt-right. She has denied this.

In April 2020, Seibt said her formal work with the Heartland Institute had come to an end. She said that it was her decision not to renew a contract, and it was made because the Landesanstalt für Medien NRW threatened to delete her YouTube channel on the grounds that she wants to influence German politics for an American think-tank.

A 2020 joint investigation by Correctiv and Frontal21 revealed that the Heartland Institute's James Taylor considered Seibt to be the star of their "media strategy for the masses", in their "fight against climate protection measures" which "needs a better image"—to "move away from old white men and instead showcase a younger generation."

Since May 2019, Seibt has recorded YouTube videos using her mobile phone on topics ranging from "migration to feminism to climate change". In them, she calls herself a "climate realist".

On 4 November 2019, the Süddeutsche Zeitung, one of Germany's largest daily newspapers, spoke of her appearance at the end of the European Institute for Climate and Energy (EIKE)'s annual "International Climate and Energy Conference" held in Munich on 2 November, saying, "They have their own Greta. A climate change denier Greta." In her speech, Seibt said that before she started questioning a lot of things, like feminism and "cultural socialism", she too was a "climate alarmist".

On 3 December 2019, Seibt spoke as an invited guest at the Madrid "Climate Reality Forum", a forum organized to rebut the United Nations' climate change warnings, while Greta Thunberg spoke at the 2019 United Nations Climate Change Conference (COP25) several miles away. In 2019, Germany's AfD had embraced climate change denial as part of their political campaign in Europe, and were therefore, also aligned with EIKE. She was the only woman invited to speak at an event that is "traditionally dominated by older men".

Seibt graduated in September 2017 at 16 from Gymnasium St. Mauritz Bischöfl, a Catholic high school. Whilst attending that school, she earned first place in physics during a local regional competition of the Jugend forscht, junior division, called "Students Experiment", and second place in mathematics.

"While it is not outright disinformation, it does bear resemblance to a model we use called the 4d's — dismiss the message, distort the facts, distract the audience, and express dismay at the whole thing. The tactic is intended to create an equivalency in spokespeople and message. In this case, it is a false equivalency between a message based in climate science that went viral organically and a message based in climate skepticism trying to catch up using paid promotion."

Naomi Seibt (born 18 August 2000) is a German climate change denier. Until April 2020, she was employed by the Heartland Institute, an American conservative and libertarian public policy think tank that markets her as the "anti-Greta" (referring to the younger environmental activist from Sweden, Greta Thunberg). She has been a speaker at multiple events organized by conservative think tanks.
