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.

This is the rollcall of evolution happening in the space of a few generations, the greatest loss of living things that make up our biodiversity since the disappearance of the dinosaurs.

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.

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.

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.

Climate change is such a huge issue that it requires strong, concerted, consistent and enduring action by governments.

Our senses convey that all is not well with the natural world.
