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.

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.

At an everyday level I would reckon myself more than fortunate.

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.

I haven't chosen to make an issue of faith.

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.

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.
