The fact that greenhouse gases emitted by humans are changing the global climate system is scientifically undisputed
Just like in the 70’s when the Ice Age was here and we were all going to freeze to death, or how about Acid Rain, Allar, the Ozone hole and CFC’s and of course the $2500 reduction in Health Insurance Premiums per year, ALL GUARANTEED AND UNDISPUTED FACTS.
PUT THE PIPE DOWN UNTIL AFTER WORK, OK.
Actually this statement is correct. The significance of the effect is in dispute though. Its like if you make a campfire you also certainly are warming the planet, but also nobody thinks the amount is significant. CO2 is a greenhouse gas and emitting some into the air will have some warming effect. But the debate at issue is whether its enough to bother about. I think the answer based on data since the early 2000s is no, its not enough to bother with. But the theory won't die because promoting it pays for the research due to the corrupting influence of politics.
