It seems a lot of the debate centers around whether climate change is happening, or whether it's manmade or a natural cycle. But assuming it IS happening and it IS because of us, what exactly would the solution be? Enact policies to curb carbon emissions and encourage the development of alternative energy sources (aside: why do all you global warming hippies geek over solar and wind and not suggest the obvious pragmatic tech of nuclear power?)? Do we force other countries to do the same? Go to war over it?
