The '''average earth temperature''' (about 50° Fahrenheit) is useful in determining whether [[Global Warming]] is occurring. [[Meteorology|Meteorologists]] find it through measuring the heat in the [[ocean]]s, [[atmosphere]], as well as different places on the land. Primarily satellites are used today. | The '''average earth temperature''' (about 50° Fahrenheit) is useful in determining whether [[Global Warming]] is occurring.
