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，甲烷和一氧化二氮） ，而另一些完全是人为的（某些工业气体）。随着时间的推移，如果大气中温室气体浓度保持相对稳定，太阳发送到地球表面的能源总量应该与辐射回太空的能源总量大致相同，使温度的地球表面大体不变。
