The EPA scientists are liers on "global warming".
They say, on the official EPA website:
"Warming is now occurring over most of the globe".
But the fact is that the average global temperature peaked in 1998, nine years ago, and has not gone any higher since, in spite of all addtional man-made CO2.
The C02 gambit is a speculative scam predicting its own answer on data meant to conform to a theory, not data objectively independent of that theory.
