Unit 4 Global warming
vocabulary
What is global warming
全球气候变暖是一种和自然有关的现象。由于人们焚烧化石燃料,如石油,煤炭等,或砍伐森林并将其焚烧时会产生大量的二氧化碳,即温室气体,这些温室气体对来自太阳辐射的可见光具有高度透过性,而对地球发射出来的长波辐射具有高度吸收性,能强烈吸收地面辐射中的红外线,导致地球温度上升,即温室效应。而当温室效应不断积累,导致地气系统吸收与发射的能量不平衡,能量不断在地气系统累积,从而导致温度上升,造成全球气候变暖这一现象。
全球变暖会使全球降水量重新分配、冰川和冻土消融、海平面上升等,不仅危害自然生态系统的平衡,还威胁人类以及动物的生存。
另一方面,由于陆地温室气体排放造成大陆气温升高,与海洋温差变小,近而造成了空气流动减慢,雾霾无法短时间被吹散,造成很多城市雾霾天气增多,影响人类健康。
