It's been scientificaly and historicaly proven that planet earth has periods of global warmings and coolings every thousand years. The human involvement has nothing to do with it.
The concept that people are responcible for global warming is nothing but a lie, promoted by the leftwing liberals to achieve only one thing: To Subvert National Economy, so there gonna be more unnemployment, more reliance on goverment handouts, and finaly, more votes for the liberal democrats. Because the left knows how to play on the feelings of needy people.
"It's been scientificaly and historicaly proven that planet earth has periods of global warmings and coolings every thousand years. The human involvement has nothing to do with it. "
The fact that the planet has warmed and cooled in the past does not prove that humans are not responsible for warming this particular time.
