The seasons are the most obvious changes.

How do changes in heat energy affect the density of earths mantle material
Climate
Earths Orbit? Earths Orbit?
The Earth's orbit affects its temperature primarily through variations in solar radiation received at different times of the year due to its elliptical shape and axial tilt. These factors create seasonal changes, influencing climate patterns. Over long periods, shifts in the Earth's orbit, known as Milankovitch cycles, can lead to significant climate changes, contributing to glacial and interglacial periods. Ultimately, these orbital variations play a crucial role in regulating the Earth's overall climate and temperature.
progressive cooling of earths surface. earths heat balance could change as orbit alters.solar radiation fluctuations, periodic changes in earth tilt and orbit. loss of heat from earths surface through reduction of carbon dioxide content of atmosphere. volcanic eruptions, short term cooling of globe could increase effect if lots erupted over longer periods of time. volcanoes and climate, the little ice age 1645-1715.
The changes in the distance from the sun (due to elliptical orbit) make marginal differences in the amount of energy recieved by the earth,. > The major contributor to seasonal differences is essentially due to the tilt from perpindicular of the earths rotational axis and the fact that the axis will remain parallel throughout the earths yearly orbit around the sun, so in the northern hemisphere the winter equinox is when the top of the axis is at maximum tilt away from the sun, resulting in diffused sunlight and less daylight hours.
Mostly solar variability and changes in green-house gasses; but changes in Earth's orbit over time also has an effect.
Actually, it doesn't. The TILT of the Earth on it axis causes seasonal changes.
