WebThis changing of the obliquity-- or the changing of the tilt-- is one of these changes in Earth's rotation or Earth's orbit around the sun that might have long-term cycles or effects on Earth's climate, and maybe they do help cause certain ice ages when they act together with each other over certain cycles.

WebJun 11, 2024 · 6. Warming can disrupt ocean currents. Ocean currents and wind systems are important components of the climate system. As a result of differential heating, whereby the equator is hotter than the Earth’s poles, convection currents in the oceans and the atmosphere move thermal energy towards the poles. WebHow does the change in Earth’s tilt affect climate? The Earth’s axial tilt The tilt in the axis of the Earth is called its ‘obliquity’. This angle changes with time, and over about 41 000 years it moves from 22.1° to 24.5° and back again. When the angle increases the summers become warmer and the winters become colder.
