  We will soon learn, for example, that what we’ve been calling
“global warming” is better thought of as excess energy trapped
in the atmosphere, which will express itself in every possible
way. Like the Bush administration’s energy bill, these
manifestations will also be about “more”: more evaporation in
arid lands and then more flooding when it eventually rains; more
wind as air pressure rises from warmer areas; more extreme heat
waves like the one that killed tens of thousands of Europeans in
2003 or the one that cut North American grain yields by a third
