Before one can talk about climate change, one has to understand what climate is. How is it different from weather? What determines global and regional climates, and how does the carbon cycle—which connects the atmosphere, hydrosphere, geosphere, and biosphere—influence climate? How do we measure the characteristics of climate?
This chapter addresses these questions.
