Global Warming 全球暖化 温室效应导致全球变暖 global warming“温室效应”是指地球大气层上的一种物理特性。假若没有大气层，地球表面的平均温度不会是现在合宜的15℃，而是十分低的-18℃。这种温度上的差别是由温室气体导致的，这些气体吸收红外线辐射而影响到地球整体的能量平衡。受到温室气体的 影响，大气层吸收红外线辐射的份量比它释放到太空外的垛，这使地球表面温度上升，这个过程就是“天然的温室效应”。但由于人类活动释放出大量的温室气体，结果让更多红外线辐射被折射到地面上，加强了“温室效应”的作用。 全球变暖是目前全球环境研究的一个主要议题。根据对100多份全球温度变化资料的系统分析，发现全球平均温度已升高3～6摄氏度。其中11个最暖的年份发生在80年代中期以后，因而全球变暖是一个毋庸置疑的事实。全球变暖将带来非常严重的后果，如冰川消退、海平面上升、荒漠化等等，还给生态系统、农业生产带来严重影响。全球变暖现象最终可能会导致全球变冷，形成另一次冰河时代。就像我们在美国电影《后天》里面看到的可怕情景。 因此，探求全球变暖的起因成为重要的研究课题。分析表明，虽然地球演化史上曾经多次发生变暖--变冷的气候波动，但人类活动引起的大气温室效应增长可能是主要因素。 各国政府、企业和科学家们逐步达成共识，大家必须迅速行动起来，与气候变化作斗争。目前人们已经采取措施限制二氧化碳的排放量。许多公司正积极应对二氧化碳限排时代的到来。Global Warming 全球暖化 温室效应导致全球变暖 According to the National Academy of Sciences， the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century， with accelerated warming during the past two There is new and stronger evidence that most of the warming over the last 50 years is attributable to human Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases – primarily carbon dioxide， methane， and nitrous The heat-trapping property of these gases is undisputed although uncertainties exist about exactly how earth’s climate responds to Energy from the sun drives the earth's weather and climate， and heats the earth's surface; in turn， the earth radiates energy back into Atmospheric greenhouse gases， such as water vapor， carbon dioxide， trap some of the outgoing energy， retaining heat somewhat like the glass panels of a Without this natural "greenhouse effect，" temperatures would be much lower than they are now， and life as known today would not be Instead， thanks to greenhouse gases， the earth'
