资料简介

二氧化碳(CO2)是大气中天然的重要组成部分:动植物在呼吸过程中产生二氧化碳,植物需要二氧化碳进行光合作用;然而,大气中高浓度的二氧化碳会产生“温室效应”,将热量困在地球大气中。人类活动造成的全球二氧化碳排放量已从200年前微不足道的水平增加到2003年的每年210多亿公吨(美国能源部,2007年a)。与二氧化碳排放相关的最显著的人类活动是碳基燃料(包括石油、天然气和煤炭)的燃烧。包括政府间气候变化专门委员会(IPCC)在内的许多科学家都认识到这样一种危险,即即使是地球温度的小幅上升(称为“全球变暖”)也可能改变全球气候,并对人类健康和福利造成严重的不利后果(DOE, 2007a)。

Carbon dioxide (CO2) is a natural and important component of the atmosphere: animals and plants produce CO2 during respiration, and plants need it for photosynthesis; however, high concentrations of CO2 in the atmosphere can exert a “greenhouse” effect that traps heat within the Earth’s atmosphere. Global emissions of CO2 from human activity have increased from an insignificant level two centuries ago to over twenty-one billion metric tons per year by 2003 (DOE, 2007a). The most notable human activity associated with the generation of CO2 emissions is the combustion of carbon-based fuels (including oil, natural gas, and coal). Many scientists, including the Intergovernmental Panel on Climate Change (IPCC), recognize a danger that even a modest increase in the Earth’s temperature (called “global warming”) could alter the global climate and cause significant adverse consequences for human health and welfare (DOE, 2007a).
