Sandy was a climate change warning. Obama must now take the stage and fulfil the promise of hope the world needs.

Whenever anybody called Nelson Mandela a saint, he would say: "If by saint you mean a sinner who is trying to be better, then I'm a saint."

[Nelson] Mandela was very keen not to be understood as an exceptional person.

I think even though he [Nelson Mandela] was feted and praised as he was, he always was at pains to say, I'm a human being.

Nelson Mandela once said "I can't help it if the ladies take note of me; I'm not going to protest."

The struggle to avert catastrophic climate change is bigger than all the other struggles, whether it is slavery, democracy struggles, the woman's right to vote, and so on I would argue that if what is at stake is securing life as we know it, then there can be no bigger struggle that we face.

Nelson Mandela also spoke about how, as a human being, he's made mistakes.
