I think this poll is irrelevant, because belief doesn't enter into it. That's the beauty of scientific facts - they're going to stay the same, no matter what you think about them. The world is going to stay round even if you really believe it's flat.
As for the policy enacted in regard to these scientific facts, that's something we should all debate. We're all entitled to our political opinion, and we should certainly have our say when it comes to responding to climate change. Hence, a better poll might ask whether or not we believe in carbon regulation and taxation, cap and trade schemes, alternative energy subsidies, and other such environmental policy. But whether or not we believe in the existence of anthropogenic climate change is entirely irrelevant.
True, it doesn't matter if we believe in gravity; we'll still fall to the floor (unless you miss the ground apparently). But when you have representatives in power (US at least) which claim that climate change can't be a problem because god told Noa that the flood wouldn't happen again (or some such nonsense), then we've got a more fundamental problem to deal with first.
EDIT: and I note that while the numbers involved are obviously too low to take any broader conclusions, out of 32 votes, 40.6% are from people that don't believe humans have had a substantial impact on climate, which is worrying. Furthermore, and considering the other thread about this, they are far more vocal.
