What is global warming?
Question asked by: mrquestion
Asked on: 07 Jan 2010
Global warming is the phenomenon where the world increases its mean temperature.
For instance if it warms by 2 degrees then that is global warming.
What is interesting is that the global temperature has varied a lot over the history of the earth, but the point is that the current potential increase is supposedly caused by human action rather than a natural cyclical stage.
