Global climate change 5/1 Solar energy: incoming and outgoing -heat is stored and redistributed by winds and currents on Earth’s surface. Earth’s energy budget -temp of the surface of plant, how much energy comes in and how much energy gets radiated. -reflected by atmosphere, clouds, land, water -radiated reflected radiated back to space Sunlight shifts wavelength from short to long Comes in –short wavelength Absorbed by the water/ land –long wavelength Absorbs short wavelength and reflects long wavelength CO2 and other greenhouse gases keep heat from radiating back into space.
