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.

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.

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

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.

I believe that the quantum of our knowledge will increase considerably in the coming years and that scientists will continue to be amongst the brave voices speaking out.

You don't want to spend your life explaining yourself.

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