Taxes imposed in the name of global warming are completely bogus. There is no global warming if, by that term, you mean a sudden, dramatic increase in the Earth's average temperature. The Earth has been cooling for a decade, not warming.
It is incumbent on all of us to email, fax, call, and write our Congress critters and tell them they must vote against any legislation regarding "greenhouse gas emissions" or "global warming." Tell them that a vote for such legislation will be your vote for whoever runs against them in the next elections.
