I see myself as a climate change skeptic and a skeptic looks at the evidence and bases conclusions on the evidence rather than on belief. To hold the view that this is not an issue that you need to do something about, to hold the view that it's all a furphy takes belief.

Economic development over the past two centuries has taken most of humanity from lives that were brutal, ignorant and short, to personal health and security, material comfort and knowledge that were unknown to the elites of the wealthiest and most powerful societies in earlier times.

Carbon capture and storage, its commercial development.. is going to be the key to the future of coal. If it is successful commercially, then the Australian coal sector will be a center of prosperity and growth if it's not successful then it won't be. I think in the long run it's as simple as that.

A reduction in emissions matters more than what a country pays for it.

It is a simple fact of life on earth that there is going to be no successful mitigation of the climate change problem without a truly global effort. All developing companies or all major developing countries have to be part of that and accept substantial constraints on greenhouse gas emissions.

It crosses my mind that our generation may leave problems that are simply too hard for human society in the generations that follow. The structures that separate civilisation from disorder are thin and fragile. (But) I am not gloomy by nature so don't presume that the global community will fail the young people.
