What's the real obstacle in our fight against global warming?

In 1988, renowned NASA climate scientist James Hansen first approached Congress on the dangers of climate change and global warming. Here we are 20 years later and Hansen is repeating his warnings, but with added urgency and news of the damage that has occurred since his initial warnings went relatively unheeded.

The danger zone when it comes to carbon dioxide content in our atmosphere is no more than 350 ppm (parts per million), reports Hansen. Our current level is already at 385 ppm. "My cynical scenario is that there will be more Katrinas, massive fires, melting of the Arctic, and people will say, 'Oh my God, what have we done. We'd better undo this,'" adds climatologist Stephen Schneider of Stanford University in Palo Alto, California.

One thing all of these scientific researchers can agree on is that it's not a matter of solving the problems through the means we have available to us now; it's a matter of getting the world governments on board. "Solving this problem is technologically and economically not that difficult," said John Harte of the University of California, Berkeley. "It's proving to be politically difficult."
