Greta Thunberg changes her Twitter bio to Trump quote

Will Greta Thunberg be the hero who saves the word "clapback?"

Less than a day after Donald Trump mocked her impassioned speech at the U.N. Climate Summit, Thunberg took a subtle dig back at the president by changing her Twitter bio to the text of his tweet: "A very happy young girl looking forward to a bright and wonderful future."

It's clear that Trump's comment was intended to paint Thunberg, who reprimanded world leaders angrily on Monday for failing her generation on climate change, as overly dramatic. (She is not.)

But Thunberg's response asserts that Trump, as usual, is wrong: Her activism is filled with emotion and force precisely because a better world — a "bright and wonderful future" — is possible. It's just that world leaders, despite their immense power, aren't doing anything to make it a reality.

UPDATE: Sept. 25, 2019, 9:24 a.m. EDT Thunberg has removed Trump's quote from her Twitter bio. Her bio now reads, "16 year old climate and environmental activist with Asperger’s Join the global climate strikes on September 27th! #fridaysforfuture."
