Most people have thought of ... climate change as a problem about the environment that is separate and distinct from problems of human wellbeing.

When God made the planet, he made the plants, he made the animals, he made the Sun and the Moon, and he made us, and we're all interconnected, and when we disregard, disrespect, or damage any part of it, we do violence against creation.

Scientific monitoring is going to be terrifically important, because whatever steps we take ... we will have to monitor those steps in order to know if they're actually working.

Why would scientists dedicated to uncovering the truth about the natural world deliberately misrepresent the work of their own colleagues? Why would they spread accusations with no basis? Why would they refuse to correct their arguments once they had been shown to be incorrect? And why did the press continue to quote them, year after year, even as their claims were shown, one after another, to be false?

We don't survive without plants and animals because we rely on them, we rely on plants to put oxygen into the atmosphere, we rely on ... fish and crops and cows to eat.

It really is a very radical call ... to reject materialism as our central value and to think about the sanctity of life and what that really means if we take it seriously.

I think it is important for people to understand that there are real serious economic costs and real serious economic damages associated with inaction on climate change.
