There%26#039;s a lot less controversy about this is the real world than there is on Yahoo answers:

And vastly less controversy in the scientific community than you might guess from the few skeptics talked about here:

%26quot;There%26#039;s a better scientific consensus on this [climate change] than on any issue I know... Global warming is almost a no-brainer at this point. You really can%26#039;t find intelligent, quantitative arguments to make it go away.%26quot;

EDIT - Agent0%26#039;s argument about a flat Earth is a very good one, which shows global warming is real.
2000 years ago Eratosthenes measured the diameter of the Earth. Once the data was in, only ignorant %26quot;skeptics%26quot; who ignored the data said the Earth was flat. The scientists had a consensus that it was round. The same is true today. Being %26quot;skeptical%26quot; about global warming is exactly like believing the Earth is flat. Hey, doesn%26#039;t it look like it is?
