Abstract: We analyze global surface temperature data obtained at 13472 weather stations from the year 1702 to 1990. The mean annual temperature of a station fluctuates from year to year by typically +-0.6oC (one standard deviation). Superimposed on this fluctuation is a linear increase of the temperature by typically 0.40oC per century ever since reliable data is available, i.e. since 1702. The world population has doubled from 1952 to 1990, yet we see no statistically significant acceleration of global warming in this period. We conclude that the effect of humankind on global warming up to 1990 is 0.0 +- 0.1oC.

Abstract
We analyze global surface temperature data obtained at 13472 weather
stations from the year 1702 to 1990. The mean annual temperature of
a station fluctuates from year to year by typically  ±0.6oC (one standard
deviation). Superimposed on this fluctuation is a linear increase
of the temperature by typically  0.40±0.01oC per century ever since
reliable data is available, i.e. since 1702 (errors are statistical only,
one standard deviation). The world population has doubled from 1952
to 1990, yet we see no statistically significant acceleration of global
warming in this period. We conclude that the effect of humankind
on global warming up to 1990 is 0.0 ± 0.1oC. Therefore, contrary to
popular belief, the data support the view that human activity has had
no significant effect on global warming up to the year 1990 covered by
this study.
