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.

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.

Our carbon emissions have to eventually go to zero. We have to. Otherwise we're never going to have a stable climate and that's what our goal is for human civilization to thrive, a stable climate. We don't want one that's hotter, we don't want one that's colder, we want one that's stable.

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

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.

My faith is an enormous motivator for me to engage as well, because climate change is not just an issue that affects the entire planet, it is one that disproportionately affects those who do not have the resources to cope with this change - those whom we are explicitly told as Christians to care for.

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.
