Human activities add greenhouse gases to the atmosphere.For example,buring carbon-containing fuels such as coal,gasoline,and natural gas releases huge amounts of carbon dioxide (CO2) into the atmosphere.Growing crops and raising livestock release large amounts of methane (CH4) and nitrous oxide (N2O).There is considerable and growing evidence that these inputs are increasing the natural greenhouse effect and warming the earth's atmosphere and surface-something often referred to as human-enhanced global warming.We discuss this at length in Chapter 16.

人類活動增加溫室氣體排放到大氣中。例如，掩埋含碳燃料，如煤炭，汽油，天然氣排放大量的二氧化碳（ CO2 ）到大氣中。種植作物和飼養牲畜釋放大量的甲烷（ CH4 ）和氧化亞氮（ N2O ）。有相當多和越來越多的證據表明，這些投入是不斷增加的自然溫室效應和氣候變暖對地球大氣層和表面的東西通常被稱為人類增強全球變暖。我們討論這個問題終於在第16章。
