If you were running a solar company you may be okay - you may be able to keep growing. The question for physics is: Can you grow fast enough to begin to catch up with the damage?

For the first time in 150 years, the USDA reported there were more farms in America, not fewer. That has to make you happy.

Pat Robertson had decided that global warming was real and we need to do something about it struck me as powerful evidence that the Holy Spirit is hard at work in this question.

Without a movement pressing for change, there's little hope. We've got to work the political system to make this happen fast. The physics and chemistry are daunting. The resources on the other side are very large.

I am still a consumer; the consumer world was the world I emerged into, whose air I breathed for a very long time, and its assumptions still dominate my psyche—but maybe a little less each year....There are times when I can feel the spell breaking in my mind….There are times when I can almost feel myself simply being.

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

I also think we need unconventional political action, and I increasingly think that there is a need for people of faith to be able to do the kind of things that people of faith did 40 years ago in the heat of the civil rights revolution. This is a moral issue of every bit as much importance requiring every bit as much sacrifice, courage, and energy as that crisis did.
