Greenhouse gases (also known as GHGs) are gases in the earth’s atmosphere that trap heat by acting in a similar way to the glass walls of a greenhouse. Without this 'greenhouse effect', temperatures would drop to temperatures too cold to sustain life on

The definition of a greenhouse gas is at the same time very simple and very complicated for the ordinary man (or woman !) : such a gaz is “just” a gas mixed in the atmosphere thatabsorbs the infrared radiation emitted by the earth’s surface. We are not accustomed to these gases bec...
许多地球大气层中的化合物都是“温室气体”。这些气体让阳光自由地进入大气层。当阳光照射到地球表面，一部分阳光作为红外辐射（热）被重新辐射回太空。 温室气体吸收红外辐射的热量，并且把这个热量保存在大气层中。许多气体都有这些“温室”属性。 其中一些是大自然产生的（水蒸汽，二氧化碳，甲烷和一氧化...

before this heat gets escape back into the space, it is absorbed by the greenhouse gases present in the atmosphere. This is what makes the Earth’s surface warmer too that makes it possible for the survival of human beings on this planet. Without greenhouse effect, this planet would be a ...
