After falling for three years, carbon emissions in the United States rose in 2018. That information is based on early estimates(预测) from an independent(独立的) research group. Its new report estimates that the country's carbon emissions increased 3.4 percent last year. This would be the largest yearly increase since 2010, when the nation was recovering from a financial crisis known as Great Recession. The research also suggests that the American coal industry continues to struggle because of low-cost, plentiful natural gas. Natural gas is now by far the energy of choice in the United States. American power consumption(消费,消耗) - and carbon emissions - increased in 2018. The transportation industry was largely responsible for the nation's record emissions. Demand for gasoline(汽油) -- the fuel used in most motor vehicles -- decreased. But increases in the demand for other fuel(燃料), such as diesel(柴油) and jet fuel(空涡轮发动机燃料), made transportation the industry most responsible for U.S. carbon emissions. The report said another big producer of carbon emissions is the construction industry. Emissions from buildings and homes also were up last year, partly because of very cold winter weather in parts of the country.

背景知识:

温室效应,又称“花房效应”,是大气保温效应的俗称。大气能使太阳短波辐射到达地面,但地表受热后向外放出的大量长波热辐射线却被大气吸收,这样就使地表与低层大气温作用类似于栽培农作物的温室,故名温室效应。自工业革命以来,人类向大气中排入的二氧化碳等吸热性强的温室气体逐年增加,大气的温室效应也随之增强,其引发了一系列问题已引起了世界各国的关注。
