Natural & Anthropogenic Forces
Work through the following sets of readings dealing with some of the different causes and effects of climate change. All students will do the reading on Milankovitch's theory, then the class will be divided to complete the IPCC readings (which will then be shared between partners). To end students will work through what effect those changes are having on the plants and animals of our planet.

Thought Questions
Answer the following series of thought questions connected to the ideas presented in the Milankovitch theory, and then the two IPCC reports.
2. How do the ideas of climate dynamics and the variability of climate connect to the idea to the causes of climate change? (Connect in what impacts an areas climate versus what is causing it to change) *

3. How do you respond to the argument that what we are witnessing with our climate changing is nothing new, and that humans should not worry? (Support your argument with information from at least one of the articles). *
