You know, when I read stories like this one, I always imagine the problem suddenly reduced to a smaller scale, a scale that humans can proces. Imagine a doctor tells a patient: “I’m afraid I have to tell you that you have lung cancer. But this is a unique business opportunity for the pharmaceutical industry, and don’t worry about giving up smoking, the scientific community is still divided about whether smoking causes cancer.” What would we think of that doctor? And how come we don’t think the same way about people who either deny that global warming exists at all or who merely treat it like an opportunity to make money?
