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

We need a price on carbon that accurately reflects its real costs on our society and our wellbeing.

There is also a great deal of behind-the-scenes pressure from political funders too. And by funders I don't just mean the fossil fuel industry. Many of those exerting pressure on our society to ignore climate change, oppose climate change legislation, and shut down efforts to develop a clean energy economy are doing so out of ideology, not just economics. In the simplest terms, many large industries don't want the government telling them what to do with their businesses and they don't want any restrictions on what they can and cannot do, which includes polluting our shared environment.

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

A person of faith who shares conservative values and who says very clearly that climate change is real - and here's why we have to care about it - I think that we "unicorns" do pose a threat to people who want to muddy the waters and keep others in the dark.

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.
