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.

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.

We must also suffer the consequences of our past decisions. And for that, we must open our hearts to those in need.

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.

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.

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.

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.
