Germany’s Deutsche Wetterdienst cherry-picks its way to warming, hiding that the temperature has been cooling since 2000.

One typically regards the Deutsche Wetterdienst (DWD) as a serious organization that supplies us with reliable weather data. But when it comes to climate, doubt grows when one reads the statements made by leading DWD representatives with respect to the press conference in Berlin over the year 2013.
In it they announce “that the warming is marching on” even though this is not the case according to the DWD’s own data – especially in Germany! Such a claim can only be explained by a political instruction or a hasty allegiance to a government climate policy. Even the director of the Max Planck Institute for Meteorology in Hamburg, Prof. Dr. Jochem Marotzke, said “I don’t know of any serious colleague who would deny that it hasn’t gotten warmer over the last years.”
1990 reference period one today date reference period, which is also used in the USA. When that period is used things look quite different:
The year 2013 is 0.2°C below normal.
A second example used is that today is 1.2°C warmer in Germany than in 1881. Here as well a low temperature reference point is selected again. If, for example, the year 1860 were selected, then the difference would be only half as much, approx. 0.6°C.
And there is no mention of the fact that the annual temperatures in Germany dropped 0.6°C from 2000 to 2013 (using DWD data!) and that 2013 was the second coldest year of the last 14 years (Figure 1). It was not possible to find any chart showing the recent development at any of the DWD’s Internet pages. Obviously it just doesn’t fit with the prescribed climate ideology. Also when one considers the time period since 1990, there has not been any temperature rise. Instead there has been an almost constant level.
A third example mentioned by the DWD is the claim that the 1983 – 2012 time period is likely the warmest of the last 1400 years, citing the IPCC report. Doesn’t the DWD have its own historical data? Doesn’t the DWD know that not only 1000 years ago was it just as warm as today, but also over the last 3200 years it was just as warm on multiple occasions (and that without the influence of CO2)?
Figure 2 depicts the climate history which shows that warm periods were always times of political stability and economic prosperity. On the other hand the cool periods that occurred between the warm ones were times of instability (migration) and famine occurring due to drought.
