The world has much more coal, oil and gas in the ground than it can safely burn. That much is physics.
Anyone studying the question with an open mind will almost certainly come to a similar conclusion: if we and our children are to have a reasonable chance of living stable and secure lives 30 or so years from now, according to one recent study 80% of the known coal reserves will have to stay underground, along with half the gas and a third of the oil reserves.
If only science were enough.
If not science, then politics? MPs, presidents, prime ministers and members of congress are always telling us (often suggesting a surrender of civil liberties in return) that their first duty is the protection of the public.
