Why the Tilt Has Changed Over Time

Earth 's obliquity is not fixed. It varies between about 22.1 ° and 24.5 ° over a cycle of routly 41,000 years due to gravitational interactions with otherplanet, primaryly difficer and Saturn. These subtle changes in tilt can an ammplify or dampen seasonal differences across millennia, profoundly influencing Earth' s long-term climate Patterns. Thi variation in axial tilt is a key diment of the longer- m climate shifts known ai knows Milankovcles.

For example, when the tilt angle is larger, seasonal contrasts intensify - summers presente hotter and winters colder. Conversely, a smaller tilt reduces seronal extremes, producing milder winters andd cooler summers. These variations feult the growth andd retreret of ice sheets and can trigger shifts between glacial and interglacial perios, making obliquity a culal diretraf Earth 's paleoclimate.
