Questions:

When is Earth closest to the Sun in its present orbit? How does this "close pass" position affect the amount of solar radiation received in the Northern Hemisphere and in the Southern Hemisphere?
Earth's tilt has been slowly decreasing from its maximum of 24.5° ~11,000 years ago. In which season, winter or summer, were the polar regions receiving above long-term average solar radiation 11,000 years ago and how did it affect the glacial volume in the Northern Hemisphere?
Imagine that the Earth's axial tilt is not 23.5 degrees but 43.5 degrees. How different would Earth's seasons and seasonal temperature distribution be compared to our present situation?
What evidence did the scientists use to prove that the monsoons weaken and strengthen cyclically on the orbital time scale?
How do scientists use fossil corals to determine the volume of water that was tied up in ice sheets on land during the past Ice Ages?
