Global warming is a hoax

So is global warming actually a hoax?
This website seems to think so.

And of course we have the counter point here

Now technically, Global warming is the increase in the average measured temperature of the Earth's near-surface air and oceans since the mid-20th century, and its projected continuation.
But is anything besides the debate actually heating up?
The EPA runs a climate change website

"On Feb. 2, 2007, the United Nations scientific panel studying climate change declared that the evidence of a warming trend is "unequivocal," and that human activity has "very likely" been the driving force in that change over the last 50 years."

ABC seems to be fairly even handed, although to me they seem to be leaning more towards myth.

The "company line" seems to be that Global Warming is indeed real.
But in the online world, the opinion seems to be fairly evenly split.
Of course both sides call the other "crazy" for not believing the way they do.
That's pretty much standard.

So as always it's up to YOU to do the research and decide.
