People have taken advantage of the very well-trodden pathways that divide science and faith on other issues, such as creation, evolution, and the age of the universe, to pigeonhole climate change as yet another variant on the same theme.

We must prepare for a changing climate by incorporating climate preparedness into every aspect of our planning - for food, water, health, energy, even national security. We must reduce our emissions to prevent even more dangerous change.

It's easier to deny the reality of the problem altogether than acknowledge that it is real.

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.

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.

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

Natural gas is a very flexible source of energy that can help us bridge the gap between our current high-carbon economy and our zero-carbon future.
