Unit 2 explains the radiation budget of the Earth, incoming and outgoing energy and what the role of greenhouse gases is in this. Carbon dioxide and methane are discussed more in detail with their sources. A special role plays water vapour. It is the most important natural greenhouse gas and we are very unsure about the role it will play on a warming Earth in the future.

 

global warming trend

During the recent decades the average temperature of the Earth has been dramatically increasing. The greenhouse gases play an important role in this.
