全球變暖指的是在一段時間中，地球大氣和海洋溫度上升的現(xiàn)象，主要是指人為因素造成的溫度上升。目前世界范圍內(nèi)認(rèn)為主要原因很可能是由于溫室氣體（代表氣體二氧化碳）排放過多造成。近100多年來，全球平均氣溫經(jīng)歷了：冷→暖→冷→暖四次波動，總的看氣溫為上升趨勢。進(jìn)入八十年代后，全球氣溫明顯上升。Whatarethecausesoftheglobewarming?工業(yè)廢氣的排放Themainreasonistheexcessivecarbondioxideemissions.PlantdamageTheeffectsofglobalwarmingcanhavemanyunforeseensideeffects.
