Trump appears to mock Greta Thunberg, and she returns the favor

Despite being just 16 years old, climate activist Greta Thunberg was not afraid to address a group of the world’s most powerful people, angrily warning them that they’re not doing their jobs when it comes to the climate crisis. Her speech during the United Nations Climate Action Summit gained widespread attention — even from President Trump, who skipped the speech but later appeared to mock the teen on Twitter.

At the U.N. on Monday, for about 10 minutes, dropping in unexpectedly after the White House press secretary said he probably wouldn’t have time. He and Thunberg did cross paths at the U.N., and in a brief moment caught on camera, Thunberg is seen staring intently at Mr. Trump has he talks to reporters. They did not appear to interact.

This is not the first time Mr. Trump has skipped international climate discussions. He declined to appear at annual G-7 climate sessions in France this year and in Quebec in 2018. He has also undone many of President Obama’s environmental initiatives, withdrawing the U.S. from the Paris climate agreement and rolling back emissions regulations like the Clean Power Plan.
