气候变化,全球变暖对海洋及其影响

作者(年代):巴德伊斯兰教

突然的气候变化发生在世界各地。温室气体二氧化碳的水平增加在世界不同的地方。其他温室气体是水蒸汽,甲烷、臭氧、氧化氮、氟化气体。温室效应是一个过程,使地球温暖足以让人,植物和动物生活。在过去的十年中表面空气温度没有上升太多而深海洋的温度上升。世界海洋商店97%的水。这水吸收大气的90%的能源。地球的能量和温度的增加是由于温室气体增加。人类活动的温室气体量变化三个方面。热带雨林砍伐。 The fossil fuels are being burned. The world’s population has been increased. Global warming is affecting the world. The oceans and atmosphere interact both physically and chemically. They exchange energy, water, gases and particles. This exchange influences the earth’s climate. It also changes the state of oceans. The salinity of the oceans has been changed, which accelerated the global rainfall and evaporation, which is responsible for climate change. The sea levels are expected to rise as the water expands due to rise in temperature. The sea levels also rise as a result of melting of polar caps. Rising sea levels impact many coastlines, and a large mass of humanity lives near the coasts or by major rivers. More CO2 in the atmosphere more CO2 in the oceans. This CO2 is dissolved in water and reacts with it forming carbonic acid. The water becomes more acidic. This acidification of water significantly impacts upon the health of some fish and coral species. There are many millions of species in the oceans and each will have different sensitivities to acidification and respond in different ways. It is likely that acidified sea water will alter the makeup of marine ecosystem.
