The Sun

…

…cycles of the Sun give rise to important oscillations in the Earth's climate. Between 1645 and 1715 no sunspots were detected at all. This sudden solar inactivity coincided with a decrease in temperature on our planet, called the 'little ice age'. It is possible that the main ice ages are also correlated with the Sun's activity, although this conjecture has not been sufficiently corroborated, and the Sun may be just a co-factor in this equation. ------------------------------------------------------------------------ **Bibliography**
