What is the source of energy for atmospheric and oceanic circulations?
the sun
How can solar radiation maintain a steady temperature?
the energy of incoming shortwave solar radiation must equal
the energy of outgoing longwave radiation emitted by Earth/atmosphere
What is albedo?
the fraction of solar radiation reflected by a surface.
How can the Earth’s climate be regulated?
by the amount of incoming
solar radiation (solar constant), the albedo of the Earth, and
the concentration of greenhouse gases.
