the speech she delivered at the u.n. >> this is all wrong. i shouldn't be up here. i should be back in school on the other side of the ocean. yet you all come to us young people for hope. how dare you. people are suffering. people are dying. entire ecosystems are collapsing. we are in the beginning of a mass extinction, and all you can talk about is the money and fairy tales of eternal economic growth. how dare you. >> now, after that speech, thunberg spotted trump in the hallway and glared at him as he walked past her. hours later the president tweeted a sarcastic response. he said, she seems like a very happy young girl looking forward to a bright and wonderful future. so nice to see. chris cilliza, politics reporter and editor at large is here.
