Greta Thunberg vs Donald Trump: Teen activist changes Twitter bio in response

Swedish teenage climate activist Greta Thunberg shot back at 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?” Thunberg started missing school on Fridays a year ago to protest for climate action outside the Swedish parliament, inspiring millions of children.
