German physicists: “CO2 plays only minor role for global climate”
In a just published study in The Open Atmospheric Science Journal here, German scientists Horst-Joachim Lüdecke and Carl-Otto Weiss have used a large number of temperature proxies worldwide to construct a global temperature mean over the last 2000 years, dubbed G7, in order to find out more about the sun’s role on climate change.
Their results drop a huge surprise on the laps of scientists who have long believed the earth is warming due to human-emitted CO2.
...The authors used extensive local temperature proxy data [2 – 6] together with Britain’s Hadley CRU temperature records since 1870 and the recent satellite measurements and combined them to make up the global temperature time series G7 for the last 2000 years.

Also the pronounced minimum of 1450 AD, when the vines in southern France were killed by cold.
Also clearly shown by the climate curve is the warming from 1850 to 1995...
In particular, the sum of the three cycles shows the temperature increase from 1850 to 1995 as a result of the three natural cycles, the German researchers say, adding: “
Thus one can conclude that CO2 plays only a minor role (if any) for the global climate.”
Lüdecke and Weiss note that the present maximum of the cycle sum corresponds well with the world temperature stagnation since 1995 AD, the stagnation unexplained by current climate models.
As the dominant cycles have persisted for an extended time, one can assume that they will persist for the near future.
They write: “This allows to predict cooling until 2070 AD.”
