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.

Well I'm not convinced that expanding uranium mining is in the best interests of the country and the best interests of its environment.

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.

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.

Climate change is also clearly a matter of huge interest and concern for the scientific community.

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.

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