I never really bought the global warning thing. I always thought that the earth goes through natural climate cycles that are not produced by carbon emissions. To be sure, we should try to clean up the air, but the premise that the polar caps were melting because of man made emissions was always suspect in my mind. Today, I write this as a big blizzard has hit the east coast and temperatures all over Europe are setting historic lows. Recently, some emails were uncovered that puts into doubt the conviction of many scientists about global warming.
