No one said you're a loon or a shill. This kind of Dawkins-like extremism and arrogance has no place in science. I apologize if my comment came across that way.

No one said you're a loon or a shill. This kind of Dawkins-like extremism and arrogance has no place in science. I apologize if my comment came across that way. In my view, there is enough evidence right now that the cause of the currently observed climate change is human caused, specifically, due to our massive increase in CO2 production. This evidence comes from multiple independent sources (ice cores, tree rings, satellites) that all point in the same general direction. There isn't any alternative reasonable explanation on the table right now, one that explains all the observations. What other causes do you think there are?
