(CNN) -- It's all about money. That great big money pit where hypocrisy lives and science goes to die. Take climate change. Yeah, I hear some of you. You don't "believe in it," as though global warming is some kind of religion. Well, it sort of is. But it has little to do with God and everything to do with the color green. I discovered just how cynical I am about that "money pit" when I sat down recently with Chloe Maxmin, a 22-year-old climate activist and senior at Harvard University whose idealism shines as bright as the North Star.
