But, the preponderance of the evidence says that it does, so I choose not to smoke. With respect to global warming, the predictions of studies based on some pretty good science say it is likely to happen and measurements of things like air temperature and glacier ice thickness confirm it. Take a look at the subject "Global Warming" in Wikipedia and you'll see some clear trends.
The debate that continues today is largely political, with those who have a vested interest in continuing to depend on oil and coal continuing to fight attempts to redirect resources to clean energy sources. They have succeeded in delaying a significant effort in the US.
Incidentally, I think there still is a Flat Earth Society that denies that the world is round.

Sorry, but the costs and hardships to the economies, and the people, of industrialized nations (e.g. The United States) are far too much for the infinitesimal results to any "climate change", forecast by even by the most optimistic of warming zealots.
