For irritation

I listen to Parliament for information, debate humour and irritation.  It is mainly irritation now having been through rage, disbelief, sadness and back to irritation.  We now have the Howard tried and tested wrapping the flag around our fears and pretending to protect us from all the nasty Muslims who would do us harm at the same time as pretending to take climate change/global warming seriously while snubbing the rest of the world.
​
Imagine the following scenario much of which is already happening.

Coal prices bottom out as more counties move to renewables.  Our vast coal reserves become too expensive to dig up.
We get left behind in the new clean global energy economy.

If the Rockefeller family, the founders of Standard oil, feel that now is the time to divest in favour of investment in green energy do you take the sovereign risk of saying "they don't know" and disagree with thousands of climate scientists worldwide (including your own) and keep spruiking cheap coal?  The price per watt of coal generated power is now more expensive than solar or/and wind.

So it is not science or economics unless it is the economics of favouring your paymaster - but that would be too cynical to do or to surmise.
