Thirty years ago, they were worried about the next Ice Age - remember Buffalo being buried under hundreds of inches of snow? Now it's Global Warming. In another thirty years who knows what. Perhaps the state of the Sun has more to do with our climate than whether a few million environmentally friendly cars are on the road. Note that the Global Warming crisis has come home to roost only after a half century of progressively tougher environmental regulations in the U.S.
I pose the heterodox question: Is it likely that we (the poor dazed American consumer) are not the problem?
