Preventing climate breakdown – the four, five or six degrees of warming now predicted for this century by green extremists like, er, the World Bank, the International Energy Agency and PriceWaterhouseCoopers(4,5,6) – means confronting the oil, gas and coal industry. It means forcing that industry to abandon the four-fifths or more of fossil fuel reserves that we cannot afford to burn(7). It means cancelling the prospecting and development of new reserves – what’s the point if we can’t use current stocks? – and reversing the expansion of any infrastructure (such as airports) that cannot be run without them.
