The concentration of carbon dioxide in the atmosphere is rising and climate change is occurring, both due to human actions...

大气中的二氧化碳浓度正在上升，气候变化正在发生，这些都缘于人类活动…。

These particles bring with them many gigawatts of power that Dr Wong wants to harness to reduce the concentration of greenhouse gases in the atmosphere.

这些微粒携带数十亿瓦特的电力，王博士希望利用这种力量来降低大气中温室气体的浓度。

Nordhaus's preferred policy, for example, would stabilize the concentration of carbon dioxide in the atmosphere at a level about twice its preindustrial average.

比如诺德·豪斯所倾向的政策，将大气中的二氧化碳的浓度设定为前工业化时期平均值的两倍。

So if you are going to release 7 to 8 billion metric tons a year into the atmosphere, predictably that increases carbon concentration in our atmosphere.

Although the carbon dioxide in the atmosphere remains at a concentration of 0.03 percent all over the world, the amount in the air has not always been the same.

Before we started torching carbon stored in forests and then carbon stored underground as coal and oil, the carbon dioxide concentration of our atmosphere was about 280 parts per million (ppm).
