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.

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.

There are a range of associated impacts related to increasing temperatures which affect both evaporation rates and river systems, which are already over stressed, and these will hit farming communities and the health of crop lands.

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.

There is job growth in renewables, there is job growth in energy efficiency and there is job growth in developing innovative industries and technologies to successfully meet the challenge of climate change.

Once you start to look into the guts of climate change you find that just about every scientific institution in the world is conducting research on the issue.
