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.

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.

We have to fix climate change with the people we have right now, and to a large extent with the perspectives we have right now as well.

It's a common perception that science and religion are mutually exclusive. But there are many scientists who would consider themselves to be spiritual people. Not only that, but in the case of climate change - a scientific issue with strong moral implications and difficult decisions to be made - it's essential to connect the science to our values. And for many of us, our values come from our faith.

It's a new normal and I really do think that global weirding is the best way to describe what we're seeing.

I don't have to change the world all by myself, I just need to partner in the work God wants us to do.

One of the biggest issues with renewables right now is the fact that if the wind isn't blowing, if the sun isn't shining, we don't have energy. Many people are working on storage technology so when the wind isn't blowing, we can use the energy stored in our giant batteries, essentially. But what happens if we don't have enough stored energy?
