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...
A carbon footprint refers to the greenhouse gases released into the atmosphere because of what we do or buy. 碳足迹指的是由于我们的行为或购买的东西而释放到大气中的温室气体。 What are these greenhouse gases? 这些温室气体是什么? Carbon dioxide or CO2 is the most dominant of the greenhouse gase...

Greenhouse gases are gases in Earth's atmosphere that trap heat, and without them, the Earth would be too cold to support life. But what if there are too many greenhouse gases? This lesson will explore these gases and the greenhouse effect. ...
1. Definition of Greenhouse Gases (GHGs): Greenhouse gases are gases in the Earth's atmosphere that have the ability to absorb and re-radiate infrared radiation. This process contributes to the greenhouse effect, which leads to global warming. 2. Mechanism of Action: The key characteristic of ...
What are the main types of greenhouse gases? Experts consider carbon dioxide (CO2) the primary driver of the greenhouse effect, but it isn’t the only contributor. The impacts of other greenhouse gases, including methane (CH4),nitrous oxide (N2O) and fluorinated gases such as chlorofluorocarbons...
