Climate change is a given, continual. Man-made is an as yet unproven hypothesis. But there is lots of money to be made and politics to be done.
the temperature may or may not have risen a fraction of a degree in the past 150 years but it hasn't risen in 15 yrs.
20,000 yrs ago the ice was a mile thick at Lake Erie. 20,000 years from now the ice will be a mile thick at Lake Erie.
How will taxing me change any of this?
