In the April 16 issue of Newsweek, "Save the Planet-Or Else," Newsweek talks to Calif. Gov. Arnold Schwarzenegger about how he's taken the lead in the battle against global warming. Other articles in the issue discuss the businesses and cities that will gain or lose from climate change -- and those that are doing something now.

Global warming is a reality. The evidence makes the few remaining die-hard skeptics scramble for credibility. Temperatures will continue to rise -- and tilt the world's economic and political balance -- no matter what we do. How will we adapt?

Do you think that if we talk too much about adaptation, people will lose interest in mitigating the effects of climate change? If we don't talk about adaptation, then will fear eventually lose its grip on the public? Add your Comment.
