Evidence of rising temperatures, melting ice, rising sea levels, and damage to flora and fauna on land and in the oceans has been accumulating for several decades. Scientific bodies around the world have traced this trend to increasing levels of carbon dioxide and other greenhouse gases in the atmosphere, most of it attributable to the consumption of fossil fuels. Despite the evidence, political debate rages about the existence of global warming. "Global Warming in the 21st Century" provides a detailed review of the accumulating evidence for global warming, from the Arctic and Antarctic to the tropics, with special attention to processes that will accelerate warming as the century progresses. The book also explains scientific theories on the subject that sometimes conflict with popular assumptions. This three-volume work proposes detailed solutions, including a worldwide overhaul in energy sources.
