There is no real scientific debate over what is happening; of course there is debate over exactly how it is going to play out in the decades ahead, because this is a large experiment that we haven't done before, and no one knows precisely how one can ever precisely predict what effects this heat will have. But all the science in the last few years, or almost all of it, really serves to show that the effects are larger and more rapid than we had thought even a decade ago.

I think I have felt most profoundly that in our disruption of the most basic physical processes of creation, we are engaged not only in the act of suicidal self-destructiveness, but also in an act of thorough-going blasphemy.

In certain ways, I think the work in the Evangelical community has been the most interesting and the most promising. Partly because Evangelical congregations may be harder to convince about issues but, on the other hand, are more likely to do something about it.

One degree turns out to be enough to really unhinge all sorts of earth's ecosystems.

All things considered, the internet seems fairly environmentally benign to me. The last stats I saw showed you could do 1,000 Google searches for the gas it took to drive six-tenths of a mile. But the internet can't substitute for real connection and community.

If one wanted to stigmaitise, that's how one would do it - lots and lots of people saying "we're severing our ties".
