Since the effect of CO2 on temperature is logarithmic (increasing CO2 in theory leads to a given constant 'forcing' per doubling). I calculate it (log(360/330)/log2)) as 14.94%, or, say 15%. 15% of 3.7W/m2 is 0.55W/m2 (rather than your 0.41W/m2) and gives a factor of 15 (rounded) rather than your 21.<br />I realise this is slightly more favourable to the alarmists, butting getting it righ5t might deflect their criticism!Evil Deniernoreply@blogger.com
