Science is never settled, although scientific theories that are most widely accepted are considered to be far better than its alternatives. As a result, there is very little active discussion on the alternatives, except by kooks and those with agenda.
I don’t think algore is aware of this.
By kooks do you mean those of us that realize that SUVs weren't around to cause global warming millions of years in the past and therefore this "theory" that man is significantly responsible for global warming (uh wait a minute is it even warming any more?) is a crock? Do you mean us?
