My faith tells me that God does want people to understand climate change and do something about it.

If you can frame climate change as an alternate religion, or as one more of those issues where the pointy-headed liberal atheist scientists are trying to discredit the Bible, then you've already got a ton of people on your side who are concerned about heresy, other religions, or teaching evolution in schools.

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.

There has been a concerted effort to frame caring about climate change and the environment as an alternate religion - one that worships the creation rather than the creator, so to speak.

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.

It is certainly true that conservative Christians are much more likely to doubt the reality of climate change than mainline Christians or the unaffiliated. But when we control for political affiliation and for the important role of thought leaders in determining our opinions on social issues such as climate change, most of the faith-related bias disappears.

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.
