World Meteorological Organization
How does the sun affect climate?
All weather starts with radiation from the sun entering the earth’s atmosphere.
How does the ocean affect climate?
The ocean stores heat, moves heat through currents, and stores carbon dioxide, keeping things from getting too warm.
What effect do abrupt changes in ocean currents have on climate?
Ocean currents can carry warm water, which can raise temperatures and cause more precipitation.
Carbon dioxide released into the atmosphere by meteor impacts immediately cools and then heats the earth’s surface by hundreds of degrees Celsius.
False
