Every climate scientist has his or her own views on some issues that differ from the mainstream in detail. But the broad findings of the IPCC (Intergovernmental Panel on Climate Change) have general support amongst scientists with relevant specialist expertise. The broad wisdom of the IPCC is strongly contested by a small number, and a small minority, of reputed climate scientists. It is not contested by the large majority of specialists, and by the leaders of the relevant learned academies in the countries of great scientific accomplishment.

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.

The climate change problem is at its heart an ethical problem. It's a problem of income distribution and it's a problem of income distribution with dimensions that we don't usually think about very much.

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.

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.

A revolution in humanity's use of fossil fuel-based energy would be necessary sooner or later to sustain and to extend modern standards of living. It will be required sooner if we are to hold the risks of climate change to acceptable levels. The costs that we bear in making an early adjustment will bring forward, and reduce for future times, the costs of the inevitable eventual adjustment away from fossil fuels.
