This whole thing just boils my blood. The only sound scientific reason to reduce the use of fossil fuels is that they are a finite recourse! Frankly your horoscope has better chance of accurately predicting the future than so called Climate "Science". Man-made global warming is just a political band-wagon that people like David Cameron use to try an appear "cool". The whole thing is based on computer climate models that can be manipulated to predict pretty much anything and attribute it to pretty much anything.
P.S. so there is plenty of oil left for my children to drive round in vintage 997s I walk to work.
