1 Title: Greenhouse Gases & Climate Change 2/19 You should take notes for today s lecture & put the notes into your notebook
2 Summary of topics to will be discussed What causes climate to change? (2/19) Is there evidence that climate is changing? What will be the future effects of climate change?
3 Climate Change What causes climate to change? Variation in the Earth's Orbit Greenhouse effect and albedo variations
4 Past Climate = Continenal Glaciation (= "Ice Age) Figure 17-26
5 Figure Effects of Glaciation Sea-level change
