1940s-’80s global-mean-surface-temp normalization: Were Earth-covering sulfate aerosol clouds the cause?
Between roughly 1850 and the present day, the trend in global mean surface temperature (GMST) has, generally speaking, been positive, meaning the GMST has been rising. Interestingly, though, from 1940 to 1980 GMST stabilized. (See temperature plot at bottom). Incidentally, as reported by NASA’s Earth Observatory the GMST has increased a total of 0.7 degrees […]
