Re: @Ken Hagan
No discontinuity at all - economist Lord Stern authored a highly alarmist document - unimaginatively called 'The Stern Report' which informed government policy abut the alleged impacts and conjectured costs of the 1980-1990s global warming phase, should it continue into the 21st century. This particular economist's actions were amplified when another, London School of Economics graduate Sir John Beddington, was appointed Chief SCIENTIFIC adviser to the Government.
So even if *some* of us know that economics is an underpaid branch of astrology, that particular memo hasn't yet made it to the decision makers in our country.
