the bill would require refineries, factories and power plants to reduce greenhouse gases by 20% by 2020, and roughly 80% by the middle of the century.

该法案要求炼油厂、工厂和发电厂在2020年前减少20%温室气体排放量，而到本世纪中叶削减量大致为80%。

attempts to extend it to other sources of greenhouse gases may prove more difficult and would almost certainly face challenges in court.

打算把该项裁决扩展到其它温室气体排放源的尝试会非常困难，肯定会面对诸多法律难题。

each and every one of us is responsible for the greenhouse gases we emit in our daily actions and choices.

我们中的每个人都应该对自己日常生活活动和选择所产生的温室气体负责。

and these greenhouse gases perturb the radiation balance of climate.

这些温室气体会扰乱气候的辐射平衡。

we've gone one step further than the work that only looked at greenhouse gases and found some surprisingly large effects.

我们已经比只盯着温室气体的研究更进一步了，而且还发现了一些极为重大的影响。

agriculture produces more greenhouse gases than all methods of transport put together, and contributes to a host of other problems, from nitrogen pollution to soil erosion.

农业产生的温室气体比交通运输所有方式加起来还要多，并且还进一步促成了从氮污染到水土流失等许多其它问题。

we should be looking at the full spectrum of greenhouse gases produced during food production.

我们应该着眼于全系列的过程中产生的温室气体的粮食生产。

those in favour of a more holistic approach argue that disaggregating greenhouse gases could undermine the effort to solve the problem as a whole.

那些支持进一步通盘考虑的人认为，分开解决温室气体[问题]可能会逐渐破坏以整体方式解决问题的努力。

industrialised countries should recognise their role in the accumulation of greenhouse gases in the atmosphere and respond with bolder initiatives to cut back on future emissions, singh said.

辛格说，工业化国家应该认识到自己在大气温室气体累积过程中充当的角色，应该更大胆主动地削减未来的排放量。

we must face the facts: our emissions of greenhouse gases probably are at least partly to blame for this summer of extremes.

我们必须面对这些事实：我们的温室气体排放至少可能是造成今年夏天极端气候事件的部分原因。

until now, they were not thought to absorb and store significant amounts of greenhouse gases from the atmosphere.

直到此前，人们认为它们不能吸收和贮存显着数量的大气中的温室气体。

the finding set the stage for the government to regulate greenhouse gases for the first time, an initiative that will resonate through the economy for decades.

该发现首次为政府控制温室气体打下了基础，这一开创性行动将在今后几十年的经济活动中引起共鸣。

「we believe our approach will be the key to cost-effective transformation of greenhouse gases to fuel on a global scale, 」 he says.

「我们相信，在温室气体低价转换为燃料这一技术全球化的进程中，我们的技术将成为关键，」他说。
