I have read some magazines on different views about it.
Does it really exist?
Is it caused by humans?
If so, how much?
Or is it a natural thing for the earth?
I am under the impression that it is natural for the earth to warm up. I mean, it naturally cooled (ice age) so it obviously can warm by itself.

If it does exist, the only human that is causing it is Al Gore, by blowing a lot of hot air out of his A$$

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:

EVERY major scientific organization has issued an official statement that this is real, and mostly caused by us. The National Academy of Sciences, the American Association for the Advancement of Science, the American Institute of Physics, the American Chemical Society, the American Geophysical Union, the American Meteorological Association, etc.
