"The greenhouse effect is the process by which absorption and emission of infrared radiation by gases in the atmosphere warm a planet's lower atmosphere and surface. It was proposed by Joseph Fourier in 1824 and was first investigated quantitatively by Svante Arrhenius in 1896." [Wikipedia - Global Warming]
It's not a cabal. It's not lies. It's not a world-wide impossible hoax. And it's definitely nothing new. Gore didn't invent it but he did bring Global Warming into the public spotlight where it belongs. Get down from your lofty denier high horses before you take a hard tumble to reality and hurt yourselves.
