Methane, the primary component of natural gas and among the more potent greenhouse gases, has far more of an effect on climate change than carbon dioxide.

甲烷是天然气的主要成分，也是温室效应相对比较高的气体之一，它对气候变化的影响远比二氧化碳强得多。

Without this so-called "greenhouse effect," Earth would probably be too cold for life to exist, although a runaway greenhouse effect led to the hellish conditions now seen on Venus.

如果没有这种“温室效应”，地球将变得非常寒冷，而不适于生命的存在。但过度的温室效应导致了现在金星上所见的地狱般的景象。

But the strength of the greenhouse effect depends on the chemical composition of the atmosphere, because the phenomenon is due to the absorption of infra-red radiation by various gases in the air.
