WebAxial Tilt. Axial tilt, the second of the three Milankovitch Cycles, is the inclination of the Earth's axis in relation to its plane of orbit around the Sun. Oscillations in the degree of Earth's axial tilt occur on a periodicity of 41,000 years from 21.5 to 24.5 degrees.. Today the Earth's axial tilt is about 23.5 degrees, which largely accounts for our seasons. WebJul 21, 2024 · Solar Cycles. Magnitude: 0.1 to 0.3 degrees Celsius of cooling.
