0.023 degrees ( present rate of energy production- and you expect it to NOT increase??) a year times 100 years is 2.3 degrees- and ALL the CO2 reduction would not stop it. Look at the numbers the Goreistas have put forward- a single degree speels the death of all civilization ( to them)

A pity that the sun is a variable star, and will ( often, from past records (ie, the dinosaurs et al) )warm things up MOPRE than the greenhouse effect, without any help from man.
