How often does earth's climate naturally change?
There are naturally occurring variations that affect climate and the cycles are different:The Eccentricity Cycle (Elliptical Cycle) - This occurs about every 100,000 years and is the longer cycle. It causes the earth to cool.The Obliquity Cycle (Axial Tilt) - 41,000 years. Increased obliquity can cause summers to be warmer and winters to be colder.The Precession Cycle (Wobble) - This cycle occurs every 26,000 years and can cause seasonal changes.
What concept explains the fact that the water you drink is about three billion years old?
