I think we have a very brief window of opportunity to deal with climate change. No longer than a decade at most.

The scientific excitement in comparing theory with data, and developing some understanding of global changes that are occurring, is what makes all the other stuff worth it.

What has become clear from the science is that we cannot burn all of the fossil fuels without creating a very different planet.

What we are doing to the future of our children, and the other species on the planet, is a clear moral issue.

I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.

Scientists will say we can't blame global warming for any single event. In a sense that's right, but the fact that the frequency and intensity of these events is increasing you can blame on global warming.

Until the public demands otherwise, the policy makers will continue to serve their financiers.
