Global Warming: A Science Overview for the A/C Industry

Fossil fuels (i.e., coal, oil, and natural gas) provide about 85% of the world's energy, sustaining our standard-of-living. They are inexpensive, transportable, safe, and relatively abundant. At the same time, their use contributes to problems such as air quality and acid rain that are being addressed through various control efforts and to the problem of global warming, which is now being considered by governments of the world. This talk will focus on six key aspects of the scientific findings that are leading to proposals for significant limitation of the emissions of fossil-fuel-derived carbon dioxide and limitations on emissions of other greenhouse gases that can influence the global climate, including substances used in the refrigeration and air-conditioning industries
