I guess for me what is more significant than success is the nature of each of the songs and of the words.

It's absolutely not acceptable for people to argue that, if we are going to do anything about climate change at all, well, the responsibility lies solely with the individual.

Look, very clearly there are things that need to be done urgently in relation to climate change, and of those the most obvious is to have an enforceable and equitable arrangement delivering deep cuts in emissions into the middle of the century.

Some people are born with the necessary gift, and some work hard to build on the few gifts they have.

The core strands of my involvement in public life are a belief in the need to strive wherever possible for equality of treatment and opportunity, to ensure all people have the means to a decent livelihood.

And given that there's been probably a ten-fold amount of information about terrorism through the media than there has about climate change; I think that's quite an interesting statistic.

Life is very short; be willing to serve.
