        The Climate Wild Card

        Examine how clouds influence Earth's overall temperature in this video excerpt from NOVA's Cloud Lab. Clouds affect Earth's energy exchange with space in two ways: some clouds reflect incoming solar radiation back to space, and some clouds insulate the planet by absorbing outgoing heat. Overall, Earth's clouds currently have a cooling effect on the planet: they reflect more energy than they absorb. However, the types, numbers, and locations of clouds will be influenced by Earth's changing temperature. Scientists are studying how clouds will respond to a warming planet, and the role they might play in climate change.
