Greenhouse gases (also known as GHGs) are gases in the earth’s atmosphere that trap heat. During the day, the sun shines through the atmosphere, warming the earth’s surface. At night the earth's surface cools, releasing heat back into the air. But some of the heat is trapped by the...
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...

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 that absorbs the infrared radiation emitted by the earth’s surface. We are not accustomed to these gases ...
