Ever since we have accurate measurements of the temperature of theAlltså: “We observe no correlation of the global temperature with the consumption of oil, coal and gas, or with population. [...] So, the observed global warming since 1702 is part of the natural variability of the climate as we pull out of the “little ice age” three centuries ago.”
atmosphere, i.e. since 1702, we observe a global increase of tempera-
ture of about 0.40C per century. This warming does not accelerate in
the second half of the XX century. In fact, we see no statistically signif-
icant global warming since 1940.[2, 5] We observe no correlation of the
global temperature with the consumption of oil, coal and gas, or with
population. The atmospheric concentrations of CO2 begins to increase
around 1940[2] when oil consumption takes off, yet we observe no corre-
sponding increase of the slope of global warming.[2, 5, 10] Some studies
suggest that this is due to a balance between the heating effect of CO2
and the cooling effects of aerosols and deforestation.[1, 4] From the data
it is concluded that the accumulated effect of humankind on the global
temperature until 1990 is not statistically significant: 0.0±0.10C.[5] So,
the observed global warming since 1702 is part of the natural variability
of the climate as we pull out of the “little ice age” three centuries ago.
