My house is covered in solar panels, I'm a great believer in all this - we all should be doing this.

I think we need to think of lots of ways to communicate. And we tried some at 350. We organised what they called the largest art project in the planet's history. We do a lot with art and music and things.

The models that have been constructed agree that when, as has been predicted, the level of carbon dioxide or its equivalent in other greenhouse gases doubles from pre-Industrial Revolution concentrations, the global average temperature will increase, and that the increase will be 1.5 to 4.5 degrees Celsius or 3 to 8 degrees Fahrenheit... In Dallas, for instance, a doubled level of carbon dioxide and other gases like methane, would increase the number of days a year with temperatures above 100 degrees from 19 to 78 each year.

In the United States, cheap fossil fuel has eroded communities. We're the first people with no real practical need for each other. Everything comes from a great distance through anonymous and invisible transactions. We've taken that to be a virtue, but it's as much a curse. Americans are not very satisfied with their lives, and the loss of community is part of that.

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.

But tolerance by itself can be a cover for moral laziness.

If the Holy Spirit is capable of the heavy lifting required to get Pat Robertson to change his mind, then that strikes me as a very good sign.
