|
Milankovitch Cycles only change seasons.

Milankovitch cycles only change the tilt of the Earth.

Detailed explanation-1: -Second, Milankovitch cycles are just one factor that may contribute to climate change, both past and present. Even for Ice Age cycles, changes in the extent of ice sheets and atmospheric carbon dioxide have played important roles in driving the degree of temperature fluctuations over the last several million years.
Detailed explanation-2: -Milankovitch cycles are variations in the orbit, axial tilt, and wobble of the Earth over extended periods of time. These variations contribute to changes in climate over long periods of time. They initiate the beginning of ice ages and natural periods of global warming. (wobble) all affect climate.
Detailed explanation-3: -Milankovitch Theory has become an important tool in geologic practice and thought, and is sufficiently conspicuous to provide a rewarding target for criticism. The chief problem arising has to do with the prominence of a cycle near 100, 000 years, whose origin is not clear.
Detailed explanation-4: -For hundreds of thousands of years, the concentration of carbon dioxide in the atmosphere stayed between 200 and 300 parts per million. Today, it’s up to nearly 400 parts per million, and the amount is still rising.
