And yet. The overwhelming consensus among scientists is that global warming is real and the long-term consequences could be disastrous even by Hollywood standards. Global temperatures are expected to rise as much as 10°F by the year 2100. Rising temperatures could melt the ice caps, which would raise the sea level globally, swamping coastal cities like New York. Droughts would follow in some places, torrential rains in others, devastating agriculture. It doesn't take Dennis Quaid to connect the dots. Climate change isn't science fiction; it's already happening. And when the oceans rise and the rain starts falling, Republicans and Democrats will find themselves equally wet.
