Abstract

If man-made dust is unimportant as a major cause of climatic change, 
then a strong case can be made that the present cooling trend will, 
within a decade or so, give way to a pronounced warming induced by 
carbon dioxide. By analogy with similar events in the past, the natural 
climatic cooling which, since 1940, has more than compensated for the 
carbon dioxide effect, will soon bottom out. Once this happens, the 
exponential rise in the atmospheric carbon dioxide content will tend to 
become a significant factor and by early in the next century will have 
driven the mean planetary temperature beyond the limits experienced 
during the last 1000 years.
