Hint: Milankovitch cycles describe the collective effects of changes within the Earth's movements on its climate over thousands of years. The term is known as for Serbian geophysicist and astronomer Milutin Milankovic.
Complete answer:
These cycles affect the quantity of sunlight and thus , energy, that Earth absorbs from the Sun. they supply a robust framework for understanding long-term changes in Earth's climate, including the start and end of Ice Ages throughout Earth's history.
Of all the orbital cycles, Milankovitch believed that obliquity had the best effect on climate, which it did so by varying the summer insolation in northern high latitudes.
Milankovitch cycles operate while scales, starting from tens of thousands to many thousands of years. In contrast, Earth’s current warming has taken place over time scales of decades to centuries. Over the last 150 years, Milankovitch cycles haven't changed the quantity of solar power absorbed by Earth considerably .
Second, Milankovitch cycles are only one factor which will contribute to global climate change , both past and present. Even for glacial period cycles, changes within the extent of ice sheets and atmospheric have played important roles in driving the degree of temperature fluctuations over the last several million years.
Note:
Earth's elliptical orbit around the sun changes during a cycle of around 100,000 years in two respects: on the one hand, it changes from a weaker elliptical (circular) form into a stronger one. On the opposite hand, the axis of this ellipsis turns within the plane of Earth's orbit.
