Greta Thunberg apparently unmoved by Trump's description

Swedish climate activist Greta Thunberg changed her Twitter biography Tuesday, embracing U.S. President Donald Trump's description of her.

The American president seemed to mock the 16-year-old in a tweet following her fiery speech Monday at the Climate Action Summit at the United Nations in New York, where she shamed leaders and said "How dare you?" for not doing enough to prevent a warming world.

Trump, who had spent only a few minutes at the summit, tweeted late Monday: "She seems like a very happy young girl looking forward to a bright and wonderful future. So nice to see!"

The following day, Thunberg seemed to turn the tables on him with her Twitter bio reading: "A very happy young girl looking forward to a bright and wonderful future."

Her previous bio said: "16 year old climate activist with Asperger's. Join the global climate strikes on Sept. 20-27!" and included the hashtag, Fridays for Future.

Thunberg is scheduled to participate in Friday's climate march in Montreal where she will be given the key to the city.
