No it isn't. That's half right. The expert consensus is that it exists, the debate is how much is human caused. Most climatologists will tell you that we contribute about 5% of the greenhouse gasses into the air.

A normal volcano eruption will put more crap in the air than all human activities combined will in a given year.

What bothers me is how this has become a political debate and not a scientific one.
