Are natural cycles causing the current warming?
Over many thousands of years, the earth naturally goes through various “wobbles” in its rotation and in its orbit around the sun.

Their cycle lengths vary from 21,000, to 400,000 years, with the strongest one for earth’s climate being the 100,000 year cycle.
