New Study By German Physicists Concludes We Can Expect Climate Cooling For Next 50 Years!

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 analysis by the German scientists shows the strongest climate cycle components as 1000, 460, and 190-year periods. The G7 global temperature extremes coincide with the Roman, Medieval, and present optima, as well as the well-known minimum of AD 1450 during the Little Ice Age.

Correlation 0.84

Using further complex analyses, they constructed a representation of G7, which shows a remarkable Pearson correlation of 0.84 with the 31-year running average of G7.

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.

In accordance with the definition of climate, the blue curve in the paper’s Fig. 3, shown above, depicts the climate history as the 30-year running average of the gray curve. Noteworthy, the historically known temperature extrema are well reproduced by the blue climate curve: The Roman Optimum (~0 AD), the Medieval Optimum (~1000 AD), the Present Optimum, as well as the Little Ice Age (~1500 AD),

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.

The detailed analysis of the local records show in general a multitude of peaks, the authors say, and the G7, however, shows only 3 dominant peaks, which correspond to cycles known from local studies, of approx. 1000, 500, 200-year periods. The combination of local records to a global record apparently averages out local cycles and emphasizes global cycles.

The sum of these three dominant cycles (red curve in Fig. 3) reproduces the measured climate (blue curve in Fig. 3) with a remarkable correlation of 0.84.

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.”

    I certianly would like to see one of Greenpeace’s ships(Arctic Sunrise or Rainbow Warrior II)be trapped in the ice like before and they would be forced to burn their stupid signs and banners to keep warm

    Apparently the NY Times and LA Times are too busy chasing up fake nothing burger stories about Russia . A cooling cycle ? Does this mean Mother Nature is still in charge and not California based climate frauds ?
    Well the good news is the eco flakes in California want to separate from the USA . Kind of like a LTD or INC . company gone bankrupt . What debt ? That was the old company that was part of the USA . I love the part of their agenda where they are happy if the middle class gets wiped out . Just rich people and the serfs to clean their houses and make their wine . Yeah bring on the vote .

    For those not familiar statistics, correlation is how well data fits. A correlation of 0.84 is quite good, 1.0 is perfect. If I remember right, the correlation of the concentration of carbon dioxide to the Earth’s temperature is 0.34.

    On another note, maybe we should start a betting pool on how long into the cooling will the climate activists continue to preach their agenda.
