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.

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.

The Pro-Life cause is the preeminent cause of our time, and this struggle between the gospel of life and the culture of death will determine the destiny of mankind.

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.

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

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.

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