As someone who has not been convinced that recent increases in CO2 are an important or dominating driver of the climate system, I find the speculations about temperature changes as promoted by the IPCC quite hard to get excited about. However that is not the case with many influential or powerful people – they are very excited indeed, and want us all to put a stop to world development in a dramatic fashion. Dramatic reductions in fossil-fuel consumption along with dramatic increases in the use of inefficient generation technology such as windturbines, will in my view increase the cost of energy supplies and thus make it harder to cope with climate variation in years to come.
