There's no huge mystery. If you dig up huge amounts of carbon, huge amounts of ancient biology, hundreds of millions of year's worth of ancient biology, and flush it into the atmosphere in a matter of decades, then it stands to reason that we're going to have enormous effects, and now we can see those effects all around us.

If [a student's] college’s endowment portfolio has fossil-fuel stock, then their educations are being subsidized by investments that guarantee they won’t have much of a planet on which to make use of their degree.

In my own faith tradition, these questions have been very important. It has always been easiest for me to apprehend God in the natural world. I love to go to church, but when I really want to feel the presence of the divine I'm more likely to head up into the mountains.

We've abnegated the Kyoto treaty, we've instituted a voluntary program that's obviously not been working, we've taken every effort to excise references to global warming from official documents, to try to undermine international conferences that work on environmental issues, and on and on and on.

Unfortunately, The End of Nature turns out to be correct, although I wish it were not so. The only places that I was incorrect was, as with environmental science at the time, the estimation of the speed at which we see the effects of global warming.

I just keep trying to explain what's going on with our planet - and now, to explain what's going on with our politics, which explains why we're not doing anything about the former.

When we think about global warming at all, the arguments tend to be ideological, theological and economic.
