Greta Thunberg, the Swedish teenager who became known after protests to bring attention to global warming, delivered a speech in the United States at the Climate Change Summit, stressing that politicians did not understand the importance of such a problem. Immediately after the speech, she faced a slew of attacks and insults on social media.

American opinionist Michael Knowles called him "a mentally ill child" in one of Fox News' programs. Greta, 16, suffers from Asperger's Syndrome, a form of autism, which she calls "superpower." Fox News apologized for the embarrassing comment and a spokesman said they had no plans to invite Knowles again.

Another conservative commentator, Indo-American Dinesh D'Souza, compared her image to those of Nazi propaganda, posting a photo of Thunberg with a woman holding the swastika flag (the broken cross). "Children - especially Nordic white girls with braids and red cheeks - were often used in Nazi propaganda," he wrote.

In some other cases, her speeches were compared to those of "victims of the concentration camps of Marxism-Leninism ideology".

Donald Trump said of Greta: ?She looks like a happy young girl hoping for a bright future. I'm happy. ?The statement is believed to be ironic. On the other hand, Greta responded by placing the statement on her Twitter account.

Thunberg has described such attacks as an attempt to divert attention from the issue of global warming. "Greta has said from the beginning that they will attack her because they can't handle science," environmentalist Bill McKibben said.

In August 2018, the student from Sweden just launched a strike near Stockholm's parliament building. The minor said she would not go to school on Fridays until the government complied with the terms of the Paris Agreement on climate change, more precisely global warming. Greta has become popular worldwide and its protest has received support from thousands of students from 400 cities in Europe, the US and Australia. For more information click here.
