UNIT 1 Global Warming
greenhouse effect：The atmosphere allows a large percentage of the rays of visible light fromtheSunto reachtheEarth’S surfaceandheatit．ApartofthisenergyiS reradiatedby the Earth’S surface in the form of long．wave infrared radiation．much of which iS absorbed by molecules of carbon dioxide and water vanour in the atmosphere and which iS reflected back to the surface as heat．This is roughly analogous to the effect produced by the glass panes of a greenhouse，which transmit sunlight in the visible range but hold in heat．
ThetrappingofthisinfraredradiationcausestheEarth'S surfaceandloweratmospheric layers to WalTll to a higher temperature than would otherwise be the case．Without this greenhouse heating，the Earth’S average temperature would be only about-73C （-100F）； even the oceans would be frozen under such conditions．Alternatively．a“runaway” greenhouse effect like that found on the planet Venus would result in surface temperatures as high as 500C（932F）．
