Have you ever asked why the seasons change? It's not because of Earth's distance from the sun, it's because of Earth's tilt. Our planet is tilted about 23.5 degrees on its axis, which means different parts of Earth receive varying amounts of sunlight throughout the year. When the Northern Hemisphere tilts toward the sun, it's summer there, while the Southern hemisphere experiences winter and vice versa. Without this tilt, we wouldn't have seasons at all. The climate would stay nearly the same ye

Small cyclical variations in Earth's orbit, wobble and axial tilt play key roles in influencing Earth's climate over tens of thousands to hundreds of thousands of years. Those variations are not responsible for Earth's current warming: https://climate.nasa.gov/news/2948/milankovitch-cycles-and-their-role-in-earths-climate/ Further reading: Why Milankovitch (Orbital) Cycles Can't Explain Earth's Current Warming https://climate.nasa.gov/blog/2949/why-milankovitch-cycles-cant-explain-earths-current
