Document Summary
Anthropogenic climate change & climate change impacts - d"auria (483-506) Climate is determined by uneven distribution of solar irradiation on the planet, which sets the atmosphere in motion. Amount of radiation reaching earth (absorbed - reflected) Energy (solar radiation) is captured into the earth and 30% get reflected and earth gets warm. As the earth gets warmer, radiation and heat gets emitted back into the atmosphere. If the amount of energy-in is balanced by the amount of energy- out, the earth"s surface temperature (cid:355)ill stay constant. Between what we get and what we give, there is an imbalance of. Solar energy = vis + ir constant temperature. Solar energy > vis + ir increase in temperature. Solar energy < vis + ir decrease in temperature. Climate responds to changes within its five component systems: Changes in ice co(cid:354)erage affect earth"s reflecti(cid:354)ity.
