Abstract. Global warming or Climate change refers to long-term fluctuations in temperature, precipitation, wind, and other elements of the Earth's climate system. Natural processes such as solar-irradiance variations, variations in the Earth's orbital parameters, and volcanic activity can produce variations in climate. The climate system can also be influenced by changes in the concentration of various gases in the atmosphere, which affect the Earth's absorption of radiation.
Key words:  global warming, greenhouse gases, carbon dioxide, methane, nitrous oxide, ozone, Kyoto protocol.

GLOBALNO ZAGREVANJE I EFEKAT STAKLENE BAŠTE Globalno zagrevanje ili promena klime se odnosi na dugovremenske fluktuacije temperature, padavina, vetrova i ostalih elemenata klimatskog sistema Zemlje. Prirodni procesi kao što su varijacije u solarnoj iradijaciji, varijacije parametara Zemljine orbite ili vulkanske aktivnosti mogu da izazovu promene klime. Klimatske promene medjutim mogu da budu izazvane i promenama u koncentraciji odredjenih gasova u Zemljinj atmosferi koji utiču na apsorpciju zračenja na Zemlji i u njenoj atmosferi putem tzv. antropogenog efekta staklene bašte.
