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

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?

It's extremely hard to know what the economic consequences of any decision will be. And I'm not a, a, a financial analyst, so I, I generally don't try to make some kind of prediction about that.

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.

At a recent conference, a colleague told one of us that in IPCC discussions, some scientists have been reluctant to make strong claims about the scientific evidence, lest contrarians "attack us". Another said that she'd rather err on the side of conservatism in her estimates, because then she feels more "secure."

Scientists have been saying, for an awfully long time, that we're all interconnected. Scientists would use the word 'ecosystem' to express that idea. Obviously, people can't survive without air and water, and we rely on plants and animals for food, and plants and animals rely on us to preserve their habitats.
