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