We have an obligation to maintain the increase in standard of living for everyone. It's going to "get worse" if you mean +ppm.
You have to look at what we've achieved as a society during the period of increased fossil fuel and CO2 emissions and weigh that against what the downturn in the economy will do.
It's foolish to think we can do anything to curb emissions in the next 50 years world wide barring a significant technological breakthrough. Or a war.
You ever seen that Star Trek episode where they go into a nebula and the stuff starts sticking to the hull? The junk piles up on the hull and they're so far in by the time they realize it they have no choice but continue. That's us, we've got to "Push On Through" and hope for the best. The sooner you realize this the happier you will be.
