It's not exactly some outrageous theory that nobody can agree upon, PB.
The main issues are ocean acidification when it comes to the reef. It will be the combination of the increase in global temperatures peaking around 2030 and ocean acidification which reduces calcification in shallow water tropical corals. There are of course natural cycles superimposed on the anthropogenic warming, and failing a major stratospheric volcano occurring around 2030, that will be the time that reef systems will start to fail due to this 'double whammy' effect.
Quote: Firstly if your subscribe to the AGW theory its thw World's emissions that matter (of which we contribute 1.5%).
The 1.5% is a total strawman. The world's CO2 emissions have been in balance for millions of years. The fact that atmospheric CO2 have been building inexorably since the beginning of Industrialisation is due almost entirely to anthropogenic factors, which include the changes in tropical land use, the burning of fossil fuels and the production of cement. Those are the major factors concerned.
It's not due to changes in solar activity. It's not due to volcanoes, so why deny the inescapable conclusion?
Just because air transport is largely non sustainable today does not mean that it will continue to be non sustainable.
Times change. They always have done. The technology of 2050 will be different to that of today. The factors that will drive the economy in the future will be different to those of today.
We're not talking about sudden changes either. It's sudden change that will cause downturns in the economy.
It doesn't matter what skeptics believe or say. The momentum is there. Solar Thermal Energy and Geothermal energy are already big business in the US, and they will be equally big in Australia.
Solar Themal is already more cost effective than natural gas based power generation, so why would you subsidise inefficient technology that is about to become obsolete anyway?
As far as jobs are concerned. People can be retrained. There is currently a skills shortage in Australia, and that's not going to end any time soon.
