Computer models forecast sharp increase in temperature if heat-trapping emissions continue to rise

DENVER, CO Powerful computer models predict that winter temperatures in the polar regions of the world could rise as much as 10 degrees centigrade in the next hundred years, if no efforts are made to control production of carbon dioxide, methane and other gasses.

With projections to the year 2100, we can show what will happen if we continue with business as usualif we dont do anything to curb emissions of greenhouse gasses, said Warren M. Washington, senior research scientist for the National Center for Atmospheric Research (NCAR) and a speaker at the AAAS Annual Meeting.

Noting that concentrations of carbon dioxide and methane did not start to increase significantly until the 20th century, Washington demonstrated with charts and graphs worldwide projections for average temperature in 2050 and 2090, and compared the data to the relatively stable temperature pattern in the 1000 years that preceded the growing presence of greenhouse gasses in the atmosphere.

The greatest warming takes place in the winter hemisphere, and is strongly influenced by the retreat of snow and ice in high latitudes, said Washington, who is also chairman of the National Science Board. The range of (computer) models for global climate change at end of the century is 1.5 to 6 degrees centigrade, with most of the models in the range of 2-4 degrees. In the polar regions the changes of the order of 8 to more than 10 degrees in the winter time of the years.

The computer predictions, produced by the NCAR Parallel Climate Model and by other computer systems, are made by interpreting data gathered on sea ice, land-vegetation, ocean and atmospheric components of the climate system, and creating an interactive system for understanding how they work together to influence the earths climate.

The atmospheric, ocean and sea ice components make use of the fundamental laws of physics, Washington said. In the atmosphere, for example, equations describe the wind, tempe
