While President Bush likes to project an image of strength and courage, the real truth is that in the presence of his large financial contributors, he is a moral coward.

When you look at what has happened over the last few decades the natural fluctuations point in the opposite direction of what has actually occurred. When they run the models and plug in the man-made pollution, the correspondence is exact. Beyond that, the scale of natural fluctuations has now been far exceeded by the impact of man-made global warming.

We have to abandon the conceit that isolated personal actions are going to solve this crisis. Our policies have to shift.

Today we're dumping 70 million tons of global-warming pollution into the environment, and tomorrow we will dump more, and there is no effective worldwide response. Until we start sharply reducing global-warming pollution, I will feel that I have failed.

I am old enough to know that a red carpet is just a rug.

I don't really consider this a political issue, I consider it to be a moral issue.
