¥Initially after increasing GHG concentrations, the IR radiation to space decreases, such that
¥Solar in > IR out
–Causing
the Earth to start warming
–
¥IF GHG concentrations level off at some point, then eventually the Earth warms enough that
¥Solar in = IR out
–ÒEventuallyÓ depends on how
fast the oceans warm
¥The warmer Earth represents a new climate regime
–With bad and good consequences that we
partially understand
