United Nations - Swedish teenage climate activist Greta Thunberg shot back on Tuesday at U.S. President Donald Trump's attempt to mock her on Twitter by changing her profile on the social media site to reflect Trump's taunting remark.
Late on Monday Trump retweeted a clip of the 16-year-old's speech to a United Nations climate summit in which she angrily denounced world leaders for failing to tackle climate change by demanding: "How dare you?"
Trump, 73, commented: "She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!"
By Tuesday Thunberg shot back, changing her Twitter biography to: "A very happy young girl looking forward to a bright and wonderful future."
A Reuters video of Thunberg glaring at Trump as he entered the United Nations in New York on Monday went viral on social media. Trump has questioned climate science and has challenged every major U.S. regulation aimed at combating climate change.
