I've even had people tell me that I must not be a Christian because I think climate change is real. But you know, there's nothing in the Bible that says that. The sad truth is that our thought leaders - many of them in the conservative media and politics - are the ones telling us this isn't real, and we are believing them.

We must prepare for a changing climate by incorporating climate preparedness into every aspect of our planning - for food, water, health, energy, even national security. We must reduce our emissions to prevent even more dangerous change.

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

For many of us, our values come from our faith.

When I talk to my neighbor, or to someone at church who doesn't accept that the planet is changing, I know that they don't know any better. They've been told this information by somebody they trust and it's not their fault. They've just never heard otherwise.

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.

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.
