Life is very short; be willing to serve.

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.

In particular, Australia, because of its ancient geography, soil profile and distinctive weather patterns, is more adversely affected by climate variability than some other continents.

Humans remain entirely atmosphere dependent, so there is no choice but to respond to extreme climatic behaviour and its many effects.

And living in Australia I am relatively well off.

It's absolutely not acceptable for people to argue that, if we are going to do anything about climate change at all, well, the responsibility lies solely with the individual.

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