We have to reach out to churches and schools and help people understand science, and we have to build rapport between scientists and people of faith. Then once we get that understanding and rapport built, then everyone will be on board with climate change.

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

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 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.

When I look around, the biggest way in which we are failing to care for those in need is through ignoring climate change and acting like it doesn't exist. As a Christian, I believe that is something the church needs to know.

If we smoke, there's no magic number of cigarettes, or number of years, that we can smoke before we know we'll get lung cancer.

One of the biggest issues with renewables right now is the fact that if the wind isn't blowing, if the sun isn't shining, we don't have energy. Many people are working on storage technology so when the wind isn't blowing, we can use the energy stored in our giant batteries, essentially. But what happens if we don't have enough stored energy?
