Global Climate Change Debate • The real question is: What is the change in temperature given some change in radiative forcing? 26
Global Climate Change Debate • For example: Will a 2 W/m 2 increase in radiation flux cause global temperature to rise by 1 or 10ºC? • This is something we’re not really sure about, but we have some guesses. 27
