Earth's wobble cycle
WebMar 5, 2024 · The vortex slows, and it may wobble, slide off the pole, split into several lobes, or—in the most extreme cases—temporarily reverse direction. Regardless of their “flavor,” these disruptions have one thing in common: a spike in polar stratosphere temperatures, which is why they’re called sudden stratospheric warmings. WebJul 8, 2024 · The main reason is a regular wobble in the Moon's orbit that takes 18.6 years to complete. There's nothing new or dangerous about the wobble; it was first reported in 1728.

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. Time frame: 30- to 160-year downturns in solar activity separated by centuries. Every 11 years, the sun’s magnetic field flips, driving an 11-year cycle of solar brightening and dimming. But the variation is small and has a negligible impact on Earth’s climate.
WebJul 16, 2024 · NASA said the main reason was a regular wobble in the Moon's orbit — first detected in 1728 — that takes 18.6 years to complete. The agency said what was new was how the wobble's effects on the Moon's gravitational pull – the main cause of Earth's tides – would "combine with rising sea levels resulting from the planet's warming".
