After a mass extinction, it has generally tended to take many millions of years for life to recover. It's not something that you bounce back from, fr… - Elizabeth Kolbert

We are effectively undoing the beauty and the variety and the richness of the world which has taken tens of millions of years to reach... We're sort of unraveling that. ... We're doing, it's often said, a massive experiment on the planet, and we really don't know what the end point is going to be.

I think that people are aware of the potential impacts of climate change on Arctic species. You know, everyone has seen the pictures of the poor polar bears, you know, as the sea ice shrinks. But really, where climate change could have an even more devastating impact is in the tropics, both because most species live in the tropics—that’s just where the abundance of life is—and also because these species tend to have a very, very narrow tolerance for climatic change. They’re used to a lot of climatic stability.

you have a situation where we really need to be taking serious action on climate change, and we’re still having this surreal—I guess I would use the word—debate over whether it’s happening or not. And I think a clip like that shows that, you know, people are really speaking entirely different languages. We’re just not even speaking to each other using—you know, we’re using English, but we’re not really speaking the same language. We’re not looking at the same—well, some people are looking at scientific data, and some people are not, let me just put it that way. And it’s very, very hard to carry on, you know, a reasonable and sort of post-Enlightenment conversation.
