As we saw in Chapter 6, the Earth's weather has probably already been affected by the enhancement of the greenhouse effect due to increasing atmospheric concentrations of carbon dioxide and other gases. A continuing buildup of C02 in the air leads to the conclusion that we are in store for further increases in global air temperatures and other changes to our climate. In this chapter, we shall inquire into predictions of the likely trends in energy usage and consequently of carbon dioxide emissions that will occur for the rest of the twenty-first century. The nature of fossil fuels and their role in generating COz are then analyzed, and the prospect of burying the emissions as they are generated is then explored. We finish by considering the predictions of the consequences to the climate, and of ramifications to civilization that follow from it, if greenhouse gas emissions continue unabated or with only weak controls.
