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

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.

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.

There's no question that natural gas is a lot better than coal or oil, in the sense that natural gas produces less carbon per unit of energy produced.

We don't have a hundred years to fix climate change. We don't have a hundred years to wait until we've built all these bridges and rapport and scientific understanding and so on and so forth. 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.

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.

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.
