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.

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.

The forces that are in play on climate change essentially revolve around the generation of power, the transportation of goods and services and people, and the sorts of materials that we use to fuel the whole of our civilisation.

Humans remain entirely atmosphere dependent, so there is no choice but to respond to extreme climatic behaviour and its many effects.

The challenge that climate change presents to us, both in Australia and around the world, won't be solved by ramping up the nuclear industry.

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.
