Global warming:数据告诉我们什么?
Global warming: What does the data tell us?
摘要:
我们分析了全球地面温度的数据,从1702年到1990年在13472个气象站。一个台站的年平均温度每年的波动幅度通常为+-0.6oC(一个标准差)。叠加在这种波动上的是自1702年有可靠数据以来,温度每世纪通常以0.40 oC的线性上升。从1952年到1990年,世界人口翻了一番,但我们没有看到这一时期全球变暖的统计显著加速。我们的结论是,到1990年,人类对全球变暖的影响是0.0 +- 0.1oC。
英文摘要:
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.
