    In chapter 1 we examined what physical geography is, and how geographers study the geographic patterns found in earth systems. We have found that physical geographers are particularly well-suited for answering questions about how the future geography of planet Earth will evolve as a result of global warming and climate change. Though there are those who dispute that the current warming trends are part of a natural cycle, the vast majority of geoscientists and physical geographers agree that global warming is affecting the planet and it is caused linked to human activities. The evidence for global warming and its effects on physical and biological systems as shown in are mounting. Throughout the world, nearly 90%, and in most regions more, of the significant observed changes in physical and biological systems are consistent with warming. The earth system is quickly approaching a point when new geographies will appear.

    Chapter 2 concerns the earth system, what it is, how it formed, and the energy and material that cycles between the various system components. In this chapter we'll examine how the earth system formed and its present day functioning. We'll conclude the chapter by looking out how climate change may affect the functioning of the earth system.

    What you should already know...

    You should have a good understanding of how physical systems are visualized and modeled.
