A friend I were just wondering about this the other day in response to Water crisis looms as Himalayan glaciers melt. Is there anything we can do to stop global warming? Probably not according to a recent study of Arctic ice melting discussed in Global warming 'past the point of no return'. It looks like it's time to start developing technologies to assist in coping with the drastic climatic changes we will see over the next 50 to 100 years.

Side note: As Americans prepare to spend 200 billion dollars, global warming makes one wonder, given the likelihood of increased frequency and strength of hurricanes and higher ocean levels, whether New Orleans can ever be permanently resurrected. We will rebuild to have it destroyed yet again?
