Sun's activity shown to influence natural climate change

By analyzing trace elements in ice core samples in Greenland and cave mineral formations in China, the scientists assert that regional climate is more influenced by the sun than previously thought.

The effect of the sun on natural climate change has been one of constant debate, and its degree of influence varies dependent upon the climate modelling used. However, this recent study by Lund University may suggest that direct solar energy input affects parts of the atmosphere which then indirectly changes atmospheric circulation, resulting in increases or decreases in temperature over certain regions.

According to the researchers, a measurable variance in solar activity during the last glacial maximum (22,500 - 10,000 years ago) resulted in increased winter precipitation during periods of low solar activity.
