But no matter how big the effort to push a propaganda line might be, climate change is bigger. This, undoubtedly and regrettably, is the biggest immediate long-term environmental challenge we face. A failure to concretely come to some policy outcome on climate change has not only a negative environmental impact but also social and economic consequences for us.

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.

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

Recently though, our State Governments have discussed instigating a carbon trading scheme - the details are still to be decided - and that's an encouraging sign.

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.

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.
