The only thing that will really change global warming in the long run is if we radically increase the speed with which we get alternative technologies to deal with climate change.

We are the last generation with a real opportunity to save the world.

There is no way that we can predict the weather six months ahead beyond giving the seasonal average

If we invest in researching and developing energy technology, we'll do some real good in the long run, rather than just making ourselves feel good today. But climate change is not the only challenge of the 21st century, and for many other global problems we have low-cost, durable solutions.

On average, global warming is not going to harm the developing world.

Global warming is real - it is man-made and it is an important problem. But it is not the end of the world.
