The climate change induced by man-made releases of carbon dioxide and other trace gases is discussed. The level of carbon dioxide in the atmosphere has increased from an estimated 293 ppm in 1880 to 335 ppm in 1980, due mainly to the increased use of fossil fuels. That level is expected to double in the next century. Several carbon dioxide models are discussed, along with trends of global temperatures. The effects of the global warming are also discussed along with future research needs. (JMT)
