¥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
