In this way, the Earth maintains a stable average temperature and therefore

How Does the Sun Affect Our Climate?

Jul 16, 2009· It has been suggested that changes in solar output might affect our climate—both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes. Over the time-scale of millions of years, the change in solar intensity is a critical factor influencing climate (e.g., ice ages).

The solar atmosphere is made up of: the Photosphere (the visible surface of the Sun), the Chromosphere (an irregular layer above the photosphere where the temperature rises from 6000°C to about 20,000°C), a Transition Region (a thin and very irregular layer of the Sun''s atmosphere that separates the hot corona from the much cooler
