Is the earth’s climate changing? Most experts believe it is, and they believe they know why. Whether their models, extrapolated out for decades and centuries, are accurate is a legitimate area for debate. What experts cannot answer is what to do about climate change. It might well be that Boston or Shanghai or London will be underwater in fifty years, but it might well also be that voters—who have the right to be wrong—will choose to shift that problem to later generations rather than to risk jobs (or comfort) now.
