Climate change is a polarizing science policy debate the likes of which humankind has never witnessed before. Even President Obama's science advisor John Holdren never dreamed up this kind of doomsday scenario when he was writing books with the king of doomsday predictions, Paul Ehrlich. Women in the workforce, CFCs, acid rain, islands of garbage - nothing from past cultural debates compares to the scariness of rolling drought and melting glaciers.  What to do?
