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'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.

I feel like a physician, one who's done a scan of the patient's body and seen evidence of a potentially serious issue.

Where I live, if I put solar panels on my roof I'm not allowed to sell that energy back to the grid. I can't change that restriction myself. I need our local decision-makers to fix that.

We're not paying a real price for carbon. If we were, we wouldn't be using as much. We need to have the right perspective. It's not just about next quarter's financial return. It's about where we want to be in ten years.

My faith is an enormous motivator for me to engage as well, because climate change is not just an issue that affects the entire planet, it is one that disproportionately affects those who do not have the resources to cope with this change - those whom we are explicitly told as Christians to care for.

I think the biggest pushback comes from people who perceive me to be a threat. Having bloggers who are dedicated to making up false information about you, having anonymous people write nasty emails and letters, having organizations file legal requests for your work-related emails, and all the other things that happen can be very depressing and discouraging.
