美国国家航空航天局之所以使用“气候变化”这个词，是因为这个词更准确地反映出由于大气中温室气体总量增多而对地球造成的大范围变化。
NASA used the term "climate change" because it more accurately reflects the wide range of changes to the planet caused by increasing amounts of greenhouse gases in the atmosphere.

但是随着新线索的发现，NASA科学家们对水体总量的推测进行修正。NASA空间科学首席助理说。
But as new clues emerged, NASA scientists revised their theories about the amount of water, said Ed Weiler, NASA associate administrator for space science.
信息产业在全球产生的温室气体总量与航空业相当，约占二氧化碳总排量的百分之二，这有谁能料到呢？
Who would have thought that, globally, the IT industry produces about the same volumes of greenhouse gases as the world's airlines do-roughly 2 percent of all CO2 emissions?
而我们人类为了避免气候发生这样危险的变化，就必须限制排放的温室气体总量，而不是仅仅限制排放率来延长使用期限。
To avoid dangerous climate change we will have to limit the total amount of carbon we inject into the atmosphere, not just the emission rate in any given year.
全球范围内，信息技术行业与航空业产生的温室气体总量相同——约占二氧化碳排放总量的2%，这有谁曾想到过？
Who would have thought that, globally, the IT industry produces about the same volumes of greenhouse gases as the world's airlines do-rough 2 percent of all CO2 emissions?
译文：气体透过率(GTR)：在试验环境下，在单位时间内、单位面积上透过塑料薄膜两平行平面的特定气体总量。
Gas Transmission Rate (GTR) : the quantity of a given gas passing through a unit of the parallel surfaces of a plastic film in unit time under the conditions of test.
