A detailed look at climate sensitivity - Debunking the dangerous anti-science fantasy of the 'lukewarmers'

The amount of warming we are going to subject our children  and countless future generations to depends primarily on three factors:

The sensitivity of the climate to fast feedbacks like sea ice and water vapor (how much warming you get if  we only double CO2 emissions to 560 ppm and there are no major "slow" feedbacks).  We know the fast feedbacks are strong by themselves (see Study: Water-vapor feedback is "strong and positive," so we face "warming of several degrees Celsius" and detailed...
