Daily Review #7Describe 4 different ways that the Sun/Earth relationship changes that have an impact on Earths climate. In general, what are the Milankovitch cycles?If you wanted to have the warmest climate on Earth, according to Milankovitchs cycle, what would be true?What season is occurring in Africa in the picture labeled B in the picture to the right?

Paleoclimate RecordShows climate changes and major eruptions:Mt. TamboraKrakatoaMt. PinatuboLittle Ice Age

Daily Review #8 List as many natural causes to climate change as you can. How does a massive volcanic eruption change the climate? What would the albedo be of the Chaparral parking lot? How could we decrease the Chaparral parking lot albedo and why would we want to do that?
