What is "miniscule" to some of us (myself included), who largely feel that we aren't going to be negatively impacted by climate change in our lifetime, isn't quite as small a concern to those trying to make a living, raising a family, or dwelling in the areas of concern ( Asia, Middle East, Africa, S. America). The concerns/actions of their governments will cause impacts on our world political scene. 

When oil companies, the timber and wood products industry, fishing interests, the Department of Defense, state wild land fire agencies, and city and county governments in the SE of the United States are already taking this seriously, it doesn't matter whether you take this agree or not. Climate change denial is increasingly seen as a untenable and reactionary position by many non-Green entities, both private and public. Are they all blind too? 

Your thoughts about the option of nuclear power do mirror my own. I just don't think private industry is going to do it. They'd need help.
