Hi Value, Thanks for the link on that govt report on auto emissions and climate change. You are right, it is a long report.
This is not the board for a discussion on climate change but I do have a problem believing that we in the US can make any meaningful difference when we are only 4% of the world's population. We also lead the world in energy efficiency and technology. Another assumption in that report is that current trends will continue. Maybe they will and maybe they won't. Our planet has gone through cycles of massive warming and cooling throughout history, there is no reason to believe that will not continue, with or without man's influence.
I remember the big concern was global cooling in the 70s, then it changed to global warming and now it is the catchall "climate change". Climate changes, the unknown is how much of it is man-made.
