Hot from Copenhagen, American energy - and the destruction of Africa. Two continents adrift in hard choices. We know climate change is upon us. It's just a matter of how fast, and how bad. The struggle stretches from Washington to Denmark to Kenya, where the President's family live, among the growing millions of climate refugees.

"...civilization as we have known it, is coming to an end; brought down by a rapidly changing climate, a cancerous economic system, and the ongoing mass destruction of the non-human world."

That's the starting point for our next guest, Paul Kingsnorth, a founder of The Dark Mountain Project. Paul is a well-educated, well-published environmentalist in England. He's been arrested, helped edit The Ecologist magazine, and Greenpeace publications. He appears regularly in British newspapers, radio, and television.

I ask Paul: Can we "solve" climate change with conferences - or politics?
