the only major department in the developed world that continues at this late stage to deny climate change, which has left it entirely to democrats to try to talk about or find a solution. democrats in the senate have created a committee to work on climate change issues on their own. the chairman of that subcommittee, brian schatz of hawaii, is here with me now. what do you think about this moment, all the mobilization you're seeing this week? we've got a client forum tomorrow. there's going to be big emphasis on the climate goals and paris goals at u.n. does it mean something in domestic american politics? >> it does. there's a movement building. it's global. it's more diverse than ever, which i think is really important, and it's being led by young people. i used to be one of those young climate activists, but now i'm in the senate. >> that's depressing by the way. >> well, it's true. >> it's depressing in the sense of like enough time has gone by of young people being like, we need to do something, that you're now a u.s. senator. >> i was 19. i read al gore's book, and i decided to devote to my life to this. that's a neat story --
