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 easier to discredit the science than to say that climate change is a genuine issue but we don't want to do anything about it.

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.

There is no set period of time or total amount of carbon emissions that we can stay below to ensure we stay safe.

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.

People have taken advantage of the very well-trodden pathways that divide science and faith on other issues, such as creation, evolution, and the age of the universe, to pigeonhole climate change as yet another variant on the same theme.

For Christians, doing something about climate change is about living out our faith - caring for those who need help, our neighbors here at home or on the other side of the world, and taking responsibility for this planet that God created and entrusted to us.
