If you were watching Newsnight on 16/11/09 then you have just witnessed the cheapest conjuring trick ever devised by TV. Not even Derren Brown could have pulled off such a feat. ALL the dopes on the set were bowled over. Here is what happened--- Introduce a large amount of CO2 into an empty water bottle and watch the temperature soar!! But what you saw was quite simply a lie. Not one serious sceptic denies that CO2 is a greenhouse gas, the argument is if it IS A SIGNIFICANT greenhouse gas. The mount of CO2 that was put into the bottle, which incidentally only increased the temperature by 4 degrees, if extrapolated to the earth atmosphere would require the burning 10 times the amount of coal and oil that now exists on earth. The simple fact is that there is only 0.038% of CO2 in the atmosphere and has only increased by 0,01% in over 100 years. This is what is called a TRACE amount. The amount used in the "experiment" was massive by comparison. In the "experiment" no one stood by to assess the amount of CO2 that the nice science lady had spent time generating, but if you dump a spoonful of bicarb into vinegar you could easily introduce a significant percentage into a 5 litre empty bottle. THis was a cheap trick and totally unworthy of the BBC which seems to have joined the faithful throng, by toeing the government line that is being uses as yet another excuse to tax, tax and tax again.
