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, I help engineers and city managers and ecologists quantify the impacts. The data tells us the planet is warming; the science is clear that humans are responsible; the impacts we’re seeing today are already serious; and our future is in our hands. As John Holdren once said, “We basically have three choices: mitigation, adaptation, and suffering. We’re going to do some of each. The question is what the mix is going to be. The more mitigation we do, the less adaptation will be required, and the less suffering there will be.”
