I haven't chosen to make an issue of faith.

Climate change is so big that people who study it.. and many do.. need to speak to it. They must present scientific papers, they must appear in public, they must speak to the media and we must hear their voices. In order to get policy right, policymakers.. governments.. need to make decisions based on sound science.

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

I don't blame my own parents for the way I grew up, as quite often there is little choice in these issues.

I have always had, as I know many people have, a singular passion for Australia. I do love the sunburnt country, its ancient landscapes, its exhilarating reaches of sand and sea.

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.

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.
