Climate Machine: Heat Reservoirs, Ice
The global aggregate of glacial ice and snowpack is referred
to as the cryosphere.
Did you know?
the Antarctic ice sheet is as expansive as the U.S with an
average depth of almost 2 km amounting to more than 20 million cubic kilometers
the global sea level could rise by
80 m if the Antarctic ice sheet melted,
the energy stored in the ice cap (2.6 x 1025
J) is about the same energy content as the upper ocean in Figure
11.15. Moreover, the phase transition of melting the ice cap could
absorb a great deal of excess energy to mitigate climate changes
the transfer of energy to the ice is
small and the effects of the cryosphere are therefore relevant to climate
changes occurring over periods of 1000s of years.
