Abstract

The surface temperature curve for the Northern Hemisphere was extended to include the years 1969 through 1973 following the same procedure used by H. C. Willett, J. M. Mitchell, Jr., and C. H. Reitan. The analysis showed a slight warming of 0.02°C between the periods 1965–1969 and 1970–1973, and a significant decrease in the number of negative temperature changes at individual stations (indicating a decrease in the total area experiencing temperature decrease).
