The Arguments
In fact, what is known of solar activity over the last several hundred years correlates very well with temperature. This is what some scientists are beginning to believe causes climate change. Others feel that solar activity only explains the fine details of temperature change.
So how does the sun affect the earth's temperature? The process scientists suggest is that as earth moves through space, the atmosphere is constantly bombarded by ever-present cosmic rays. As these particles hit water vapour evaporating from the oceans, clouds form in the atmosphere. Clouds shield Earth from some of the sun's radiation and have a cooling effect.
