Katharine Hayhoe
Climate Scientist

I’m an atmospheric scientist. I study climate change, one of the most pressing issues we face today. I don’t accept global warming on faith: I crunch the data, I analyze the models, and I help all kinds of people, from engineers and city managers to ecologists and environmental justice advocates, to quantify the impacts. I care about climate change because it affects this amazing world we live in and because, most of all, it affects the poor and vulnerable among us.
