Is there anything we can do about the global increase in tropical storms? Ernst Weizsäcker, co-chair of the U.N.’s International Panel for
Sustainable Resource Management, thinks Hurricane Katrina may have provided a call to action
. Thanks in part to the terrible tragedy, the chances for getting climate change policies through Congress—or through parliaments worldwide—are greatly improving.
The longer we wait to address the problem, the more expensive it will become, says Weizsäcker. In actuality, it could take 20 or 50 years for us to see the fruits of our labor. But that realization shouldn't stop us from moving quickly, he says: Katrina was only the beginning.
