The Sun is the biggest external source of energy which affects Earth’s climate. Long-term variations of the Earth’s orbit lead to long-term (~20-400,000 year) variations in the total energy received from the Sun (Milankovich cycles) and respectively in the terrestrial temperature. For shorter time-scales, decades to centuries, the reason for solar-induced changes in the Earth’s climate are changes in the Sun itself. read more
