While several natural processes add CO2 to the atmosphere, the most significant source today in light of global warming is the human contribution—the anthropogenic effect. Until this source of CO2 is brought under control and regulated worldwide, global warming will continue to escalate, worsening each decade. This chapter looks at that dilemma. First, it examines the carbon footprints left by people and nature, then the effects that land use has on the environment. Next, it looks at the role of public land and the incurred responsibilities of the U.S. government. It will also explore issues closer to home: Which cities are at risk and what is facing society today with irreplaceable cultural losses, as well as the impacts to people and society that global warming will have. Finally, it examines the economic pressures now being felt by insurance companies as a result of climate change.
