The global temperature is
determined by:
qHow much solar energy comes in?
è affected by Earth’s obital
parameters
è external forcing to the climate system (discussed
in Weeks 7 and 8)
qHow strong the greenhouse effect
is in trapping terrestrial energy?
è affected by the composition of
the atmosphere
è (1) anthropogenic impacts on the climate system (discussed
in Weeks 9)
(2) internal
interactions among the atmosphere, oceans, and land change
global distribution and amounts of clouds and
water vapor concentration.
è related to the global water and biogeochemical cycle
