One thing that I feel very, very strongly is that we talk about Islamic countries, Islamic people, Islamic leaders, as either moderates or extremists. It's almost like there are only two categories of Muslims. And actually, that doesn't show respect. It shows lack of understanding of the diversity of Muslim thought.

The problems that the world faces - from nuclear proliferation to climate change - can't be tackled by the West alone. They need a coalition of not just West and East, but they need a coalition of Christian and Jew and Muslim.

Dangerous climate change... It's important not to be alarmist but it is very important to be alarmed

I don't think I've ever been accused of being faddish. I'm more Marks & Spencer than Ted Baker.

In the end, human history is made up of all our decisions.

Consuming three planets' worth of resources when in fact we have one is the environmental equivalent of childhood obesity - eating until you make yourself sick.

What's now urgently needed [to stop environmental disaster] is the international political commitment to take action to avoid dangerous climate change.
