全球变暖是指全球气温升高。近100多年来，全球平均气温经历了冷－暖－冷－暖两次波动，总得看为上升趋势。进入八十年代后，全球气温明显上升。1981～1990年全球平均气温比100年前上升了0.48℃ 。导致全球变暖的主要原因是人类在近一个世纪以来大量使用矿物燃料（如煤、石油等），排放出大量的CO2等多种温室气体。由于这些温室气体对来自太阳辐射的短波具有高度的透过性，而对地球反射出来的长波辐射具有高度的吸收性，也就是常说的温室效应
全球气候变暖的原因有哪些--

-------------原因有自然、人为的两方面！

人为：
1.人类大量使用矿物燃料，排放二氧化碳、甲烷、氯氟烃等温室气体；
2.森林被破坏！
