A quick look, more or less at random, at “WG2 chapter 10.2.1. Energy Demand” suggests to me that the whole IPCC process is insane, and that anyone taking it seriously is [...].
Take the introductory paragraph:
The general patterns are that in countries and regions with already high incomes, climate-related changes in energy demand will be primarily driven by increasing temperatures: heavier use of air-conditioning (hence increasing electricity demand) in warm climatic zones, and lower demands for various energy forms (electricity, gas, coal, oil) in temperate and cold climatic zones, while increasing incomes will play a marginal role.
Take a random ten year period in the future for a random country or region, and think about it. Average income will probably increase by anywhere between 0 and 100%. Gas and oil prices may go up 100% or down 50%. Add in political change, technical change, population growth somwhere between -5% and +20%, and anything else you can think of. Then try to estimate what effect a rise in temperature of one fifth of one degree will have on the use of air conditioners.
It’s insane. And the same insanity is repeated page after page for three thousand pages every five years.
