There is no set period of time or total amount of carbon emissions that we can stay below to ensure we stay safe.

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.

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.

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.

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.

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.

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.
