For, as we fill the atmosphere with heat-trapping greenhouse gases, the blunt truth is that the good times are over.

因为，当我们用热传递温室气体填充大气时，我们面对的严酷事实就是，好时光结束了。

Methane leaks have long been a concern because while methane dissipates in the atmosphere more quickly than carbon dioxide, it is far more efficient at trapping heat.

甲烷泄露一直以来就是一个隐忧因为虽然甲烷在空气中比二氧化碳分散地快但是它保温的效率却更高。

On the upside, agriculture can also dispose of heat-trapping gases, by increasing the carbon content of soils.

从好的方面讲，农业可增加土地有机炭的含量，从而将温室气体固定下来。

Production of carbon dioxide, the main heat-trapping gas, is proportional to fuel use, and the Smart claims to be the highest-mileage car powered by gasoline on the American market.

作为一种主要的截热气体，二氧化碳的产生量与燃油用量成正比，而奔驰精灵自称是美国市场单位燃油行驶里程最长的汽油驱动车辆。

The Nobel Prize winning group of scientists says carbon and other heat-trapping greenhouse gas emissions must stabilize by 2015 and then decline to head off the worst consequences from climate change.

诺贝尔奖获得者组成的科学专家组称，2015年之前，必须稳定控制碳化物等导致气温上升的温室气体排放，从而才能防止气候变化带来最糟的结果。

Carbon dioxide from the burning of oil, natural gas and coal is the main gas blamed for trapping heat in the atmosphere.

石油、天然气以及煤炭燃烧产品的二氧化碳是造成地球大气温室效应的罪魁祸首。

Only an increased greenhouse effect caused by higher amounts of heat-trapping gases in the atmosphere can explain it.

唯一合理的解释是，越来越多吸收热量的气体逐渐积累带来愈加严重的温室效应。

The amount of energy emitted by the Earth depends significantly on the chemical composition of the atmosphere, particularly the amount of heat-trapping greenhouse gases.

而地球向太空所辐射的能量多少，则在于大气层中空气成分构成，尤其是温室气体的含量大小。

The research suggests that the seas cannot indefinitely be considered a reliable "carbon sink" as humans generate heat-trapping gases linked to global warming.

该研究建议，人类再不能把各大洋当作可以依赖的“碳库”而随意制造导致全球气候变暖的温室气体。

Carbon dioxide is the second most important greenhouse gas (after water vapour), trapping heat in our atmosphere and increasing global temperatures via the greenhouse effect.

排在水蒸气之后，二氧化碳是第二大重要的温室气体，它阻止我们的大气散热，并通过温室效应增加全球温度。

For nearly 20 years, the United States has resisted mandatory limits on heat-trapping emissions.

将近有20年美国一直抵制强制性限制温室气体排放措施。

The timing of yesterday's report was also significant, with the House of Representatives considering a bill that would cap heat-trapping emissions.

昨天报告发布的时间也很有意义，那时众议院正在讨论一项减少温室气体排放的方案。

Emissions from cars, trucks, buses and other vehicles in the booming cities of Asia, Africa and Latin America account for a rapidly growing component of heat-trapping gases linked to global warming.

在亚洲、非洲和拉丁美洲的那些蓬勃发展的城市里，小轿车、卡车、公交车以及其他车辆产生的排放在飞速增长，而这些排放的温室气体和全球变暖直接相关。
