I feel that one of the most important things I can do is connect climate change to the values, the faith, and the issues we already care about. And if, in the process, I have to sidestep around some very explosive mines, I will do that.

Huge advances in clean energy technology are happening all the time. Solar and wind are booming. New ways to generate energy from our windows, the paint on our walls, and even our bike paths are being invented all the time. Technology is moving forward, but it needs to be moving forward faster.

The word "evangelist" means someone who spreads good news. Studying the impacts of climate change as I do, it's hard to come up with good news. In many ways I feel more like a Cassandra or a Jeremiah than a good-news evangelist.

The first thing we can do as individuals and as communities, like a school or a university or a church, is cut our energy use. Do an energy audit or measure our carbon footprint using online carbon calculators that are free, easy, and cheap. Get a list of the ways that we can stop wasting so much energy and save money.

I think it's interesting that the United States and Australia are two of the most individualistic nations in the entire world in terms of national personality.
