Cities generate most of the global economy, and most of its energy use, resource demands and climate emissions. How we build cities over the next decades will largely determine whether we can deliver a bright green future.

We unfortunately already live on a planet where the climate has changed and will continue to change no matter what we do now. We're playing a game of making the problem less bad rather than preventing it.

Climate change is not a discrete issue; it's a symptom of larger problems. Fundamentally, our society as currently designed has no future. We're chewing up the planet so fast, in so many different ways, that we could solve the climate problem tomorrow and still find that environmental collapse is imminent.

The most climate friendly trip we are ever going to take is the trip we never had to take because we were close to what we wanted.

I don't know if it's just my age or the climate or the high altitude or some of those old-cowboy values rubbing off on me, but I've grown slightly mellower living in Wyoming. I think if you ride into the West on a high horse, you pretty soon end up in a pile of manure.

Climate change is a security threat that Africans have had to deal with all of our lives.

If every country's climate policy was driven purely by environmental science, we may have no need for international agreements.

We have changing weather patterns, and we have climate change. This is the science. I hope that my party will come to be comfortable with this because we have to operate in the realm of knowledge and science.

My district has been hit with three 500-year floods in the last several years, so either you believe that we had a one-in-over-100-million probability that occurred, or you believe as I do that there's a new normal, and we have changing weather patterns, and we have climate change. This is the science.
