When you can predict the trajectory let me know and we'll get rich selling either A/C's or heaters. At this point I do not believe there is enough unequivocal evidence that individuals are willing to invest their own money in changing their lifestyles. However, they are more than willing to spend somebody else's money to address the "problem".

It's always easier to commit somebody else's wealth to a risky venture than to commit one's own wealth. It's base human nature.
