Obviously it’s become necessary to focus more attention on shenanigans from Germany’s DWD National Weather Service.
Lately they have developed a seemingly activist habit of blaming everything on “global warming” and using dubious tactics in doing so. These tactics include putting out deceptive and misleading press releases for the media to spread to the public.
The latest episode is described by Dr. Sebastian Lüning and Prof. Fritz Vahrenholt at the Die kalte Sonne site here.
A couple of months ago the Deutsche Wetterdienst (DWD) worried that frosts seemed to be occurring less often in mid May, hinting that their seemingly lower frequency of the recent past was due to global climate warming. They wrote that over the recent years that “they often have not occured at all“. They added:
Recent studies by the Deutsche Wetterdienst show that the frequency of cold snaps in mid May foremost in the southern region was significantly under 50%. […] Many experts trace the changes to climate change, among other things, because the ongoing warming of the global atmosphere is leading to less and less frosty May cold snaps. The earlier and possible future changes in mean temperature for May, the number annual frost days, and many other figures are shown at a glance at the Deutsche Klimaatlas.”

However, Lüning and Vahrenholt point out that the DWD fails to provide any charts illustrating this. But looking at the Deutsche Klimaatlas we find a chart of May mean temperature for Germany. The following chart shows Germany’s mean May temperature for the past 130 years:

Suddenly it becomes clear why the DWD did not present any chart in its press release: May has not warmed at all in 100 years!
What one does see is a cyclic pattern with warm phases 1915-1950 and since 1985. The curve in fact follows almost precisely NAO ocean cycle. Lüning and Vahrenholt write that it is “peculiar” that the DWD would assign the May frosts as being a victim of climate change: “We’d like to see a little more realism and transparency from the DWD.”
German climate enthusiast Josef Kowatsch then provided a temperature curve for May for all of Germany going back to 1915. The chart is based on the DWD’s own data.
Clearly one sees the distinct oceanic cycles in the chart:

Note how in fact Germany temperature trended downward from 1915 to about 1985, despite rising CO2 emissions during the period. The hottest May took place early in the 20th century.
Strangely, although Europe’s climate is directly coupled to North Atlantic oscillations, one never hears of this in the German media. The problem for this has to do in part with the DWD press releases of the sort we’ve been seeing lately. With such misleading press releases, it should not be of any wonder that Europeans are now accustomed to having everything blamed on “man-made climate change”.
At Europe’s climate institutes like the DWD, oceans and the sun do not exist.
