Human activities add greenhouse gases to the atmosphere. For example, burning 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.

人類的生活會增加那些造成溫室效應的氣體到大氣中，舉例來說，燃燒含有CO2的燃料，如...煤，汽油和天然氣體將會釋放大量的CO2到大氣中，種植穀物和飼養家畜同樣也會釋放大量的甲烷，氧化亞氮，這裡有相當多的證據證明那些投入物(那些氣體)會增加自然界的溫室效應和使大氣變溫暖，然而在地球表面上的某些物質跟人類增加地球暖化有關聯，我們將在第16章詳細討論
