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

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。

The first bacteria, for instance, consumed carbon dioxide, removing it from the atmosphere and limiting the effect of this greenhouse gas.

举例说，最初的细菌消耗了二氧化碳，从大气中吸收了它并限制这一温室气体的作用。

If this phenomenon, called "outgassing," were to kick in, it could inundate the atmosphere with carbon dioxide, perhaps doubling or tripling the effect of the past century of human industry.

如果这种被称为“出气”的现象开始发挥作用，它可能以二氧化碳淹没大气，也许比过去一个世纪人类工业的影响还要大一倍或两倍。

Since both of these chemicals are more potent greenhouse gases than carbon dioxide, this effect, too, should help combat global warming.

The award winning Bengtsson, highly decorated by scientific bodies across the globe, also pointed out that the heating effect of carbon dioxide (CO2) is logarithmic, which means the higher the concentration is, the smaller the effect of a further increase.

It said the gases had "very high global warming potentials compared to carbon dioxide", as an amount about 1g in weight could have the same effect as 1 ton of carbon dioxide being released into the atmosphere.
