David Attenborough i the Guardian:
“[It] does worry me that most powerful nation in the world, North America, denies what the rest of us can see very clearly [on climate change]. I don’t know what you do about that. It’s easier to deny….The situation is worse than we thought [in the Arctic]. The processes of melting are more volatile than we thought. More complicated. The ice cap is really melting faster than we thought.”
