In any event, it is important to remember that public opinion does not change the physical reality. Even if 100% of people of both parties believe in anthropogenic climate change, if the reality is that mankind is not responsible, then public opinion to the contrary does not change that fact--and vast amounts of money could be wasted in curbing CO<sub>2</sub> emissions when there is no need. On the other hand, if anthropogenic warming is occurring, then no amount of public denial will cool the climate down again--only positive action will, and curbing CO<sub>2</sub> emissions could save people money (such as with more efficient cars and homes). | In any event, it is important to remember that public opinion does not change the physical reality.
