The current concentration of carbon dioxide in the atmosphere is about 350 parts per million. Human activities are having a serious influence on atmospheric carbon dioxide concentrations, which are rising so fast that current predictions are that atmospheric concentrations of carbon dioxide will double in the next 60 to 100 years. The Intergovernmental Panel on Climate Change (IPCC) report in 1993, which represents a consensus of most atmospheric scientists, predicts that a doubling of carbon dioxide concentration would raise global temperatures anywhere between 1.5° C and 4.6°C. The IPCC report issued in 2002 raised the temperature prediction almost two-fold. The recommended rise in temperature is greater than the changes that occurred in the past between ice ages. The rise in temperatures would not be uniform, with the smallest changes at the equator and changes 2 or 3 times as great at the poles. The local effects of these global changes are tough to predict, but it is generally agreed that they may include alterations in ocean currents, increased winter flooding in some areas of the Northern Hemisphere, a higher incidence of summer.
