Well there's a silver lining. Global Warming is a very young theory that has been pushed to prominence too soon by politics and money. There is still a lot of SCIENTIFIC opposition to it -- specifically there are other purely scientific explanations for any warming. Thus if GW is taught in schools (it shouldn't, as it's not been properly vetted yet), then other scientific opposition should be taught.
I know. But we can't show that this is a normal, cyclic event if we have to throw out all the evidence that goes back more than 6,000 years. If the only evidence we're allowed to consider is what's occurred in recorded history, and with directly observed climatic readings the debate is heavily weighted in favor of a conclusion that GW is caused by industrialization.
