If I wasn't against all this climate change drivel before, I certainly was after last night's shambles on Channel 4.
Firstly, on the climate change issue, the Vostok ice cores, which covered 500,000 years shows that the climate changes naturally and CO2 varies naturally over about a 100,000 year cycle, with the temperature varying by about 11C from base to peak and CO2 levels, which correlate with the temperature change very highly, varies from a low of 180 ppm to a peak at 270 ppm before both world temperature and CO2 dips shortly afterwards, and very quickly.
There's little doubt that we are contributing to atmospheric CO2, but the CO2 level passed 270 pm way back in 1995 and now stands at 408 ppm, well beyond the tipping point.
So to me, its not global warming we need to worry about, but global cooling, and at a staggering rate, we may indeed need more fossil fuels and its highly unclear that wind turbines wouldn't ice up and fail in extreme low temperatures.
However, on to the debate.
The first thing to say was they all talked soundbite rubbish. In the whole debate, only ONE costing was actually mentioned and that was by the greens who quoted 38 bn just to properly insulate the housing stock.
Other than that, there was no costings for anything anyone said. They competed over timescales with the greens sticking to a ridiculous 2030 and Labour was not much better.
On electricity supply, they were equally fantastical. Despite the general acceptance that electricity supply needs to at least double by 2050.
Wind power is now 30% by capacity currently but if supply is to double its only actually 15%. They said they wanted 80-90% from wind and solar, so expect everything to be covered in wind turbines.
They still keep taking about solar, but its counter generative to demand and the solar flux at our latitude is low and not aided by high cloud cover.
But they fail to address the key issue, security of supply. In the event of a UK wide meteorological "blocking high" temperatures in the UK plummet and electricity demand goes through the roof. However, a blocking high, which can last from several days to weeks means there's virtually no wind anywhere in the UK.
Where is the power for our homes, hospitals and businesses going to come from? If its electric cars, where are you going to be able to go to if you can't charge your car?
If Ambulances are batter powered, where are they going to be recharged?
The only thing I found out last night was the hot air coming from the Westminster lefties will be the only thing keeping us warm.
