Germany’s DWD National Weather Service has developed a nasty habit of putting out warmed up press releases for announcing monthly mean data, and then later very quietly revising the data downwards.
Result: the public believes that warming is happening when in fact there really isn’t any.
German skeptic site wobleibtdieglobaleerwaermung (whereistheglobalwarming) writes a post titled: “What’s wrong with the DWD? Once again a downward correction. June 2015 was 0.2° Celsius colder than reported in the press releases“.
It describes how the June 2015 mean temperature for Germany was overstated by 0.2°C in its press release. It adds:
Also in the two earlier months of May and April, and the entire spring of 2015, the press releases reported a mean temperature that was elevated 0.2°C. DWD correction: May and spring 2015 were 0.2°C less ‘warm’ than announced in the press releases – spring 2015 now 1.4°C colder than a year earlier.
The overly hasty DWD press release announcing the June 2015 data states:
” …The first month of the summer with a nationwide mean temperature of 16.0 °C was 0.6°C above the international valid reference period of 1961 to 1990. Using the 1981 to 2010 reference period the deviation was still 0.3°C…”
Here the wobleibtdieerderwaermung site also points out yet another sloppy error made by the DWD: the difference between the two reference periods for June is in fact 0.4°C, and not 0.3°C, citing a 2014 DWD press release here.
So, did the DWD issue a correction to inform the public of the true June 2015 result, that it was in fact cooler then they had claimed earlier? The wobleibtdieerderwaermung writes:
At the DWD homepage http://www.dwd.de/ one finds at a well hidden location, after a total of seven (7) clicks, the value of 15.8 °C for June in Germany – all the way down, to the right.”
In other words, the DWD made sure to bury the real results, to keep them as much out of sight from the public as they could.
wobleibtdieerderwaermung suggests that the DWD ought to issue a new press release with the following content so that the public can be properly informed:
…The first month of the summer with a nationwide mean temperature of 15.8 °C was 0.4°C above the international vaild reference period of 1961 to 1990. Using the 1981 to 2010 reference period the deviation was only 0.0°C, and thus was exactly the mean for the WMO reference period…a climate warming in Germany’s June 2015 is thus not detectable over the last 35 years.”
So what’s compelling the DWD to engage in the habitual deceptive behavior? wobleibtdieerderwaermung speculates that all this probably has nothing to do with error and has more to do with “political intentions”.
Yet another government institution that we can no longer believe. Little wonder trust in government is near an all-time low.
