Instead of relying on just computer climate models, which skeptics don't trust, Hansen builds a powerful case for global warming based on the geologic record and simple thermodynamics. He sees undeniable signs of danger, especially from rising ocean levels, but he also believes that we can slow or halt global warming affordably--if we start right away. Politically, that's the rub. As time slips by, our leverage over the problem melts away. President George W. Bush's administration implies that it will get more serious about global warming after further years of study determine the scope of the problem (tick...tick...tick...).
