Consider the fact that today, the Perihelion of Earth's orbit around the sun occurs in the Northern Hemisphere winter. In 10,500 years, the Perihelion will occur during the Northern Hemisphere summer.
1. Explain how the Northern Hemisphere winter temperatures and summer temperatures would each change in 10,500 years, just due to precession. Be sure to justify your answer.
2. How would this affect the presence of Northern Hemisphere glaciers (grow, decay, or stay constant)? Explain why.
