　　5 the energy of sunlight is concentrated, to pass

　　through, they absorb some of the longer-wavelength,

　　infrared emissions radiated from the Earth‘s surface,

　　radiation that would otherwise be transmitted back

　　into space. For the Earth to maintain a constant aver age

　　10 temperature, such emissions from the planet must

　　balance incoming solar radiation. If there were no

　　car-bon dioxide in the atmosphere, heat would escape

　　from the Earth much more easily. The surface temperature

　　would be so much lower that the oceans might be a solid mass
