Earth’s climate follows a natural cycle of ice ages and warm periods. A new study shows that small orbital changes drive these shifts.

Scientists have determined exactly how Earth's orbit and tilt affect glaciation and deglaciation, based on the length of these parameters' cycles and clues hidden at the bottom of the ocean.

Carbon emissions probably canceled Earth’s next icy climate appointment, expected to occur in 10,000 years In a nutshell Earth naturally cycles between ice ages and warm periods based on three astronomical cycles: precession (Earth’s wobble),
