When we damage the environment, we damage everything we depend on.

The same mentality that leads to environmental despoliation, environmental destruction, also leads to damage to people.

Yet again, unscientific claims were being circulated broadly, but the scientists' refutation of them was published where only fellow scientists would see it.

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.

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.

Many people have the impression that there is significant scientific disagreement about global climate change. It's time to lay that misapprehension to rest. There is a scientific consensus on the fact that Earth's climate is heating up and human activities are part of the reason. We need to stop repeating nonsense about the uncertainty of global warming and start talking seriously about the right approach to address it.

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