“The Met” – as it is known – didn’t bother to warn anyone that is had “updated” their temperature data for their HADCRUT4 and CRUTEM4 data sets, choosing instead to simply unleash them on the public.
The folks at WUWT couldn’t help but notice that the data “updated”….
…are concentrated in the last 16 years, a period that the Met Office is under scrutiny for the lack of warming in their data.
Also, some of the regional changes appear quite contrived, e.g. it looks like they found five hundredths of a degree of extra warming in the Northern Hemisphere in the last couple years.
South America they found almost a tenth of a degree of warming over the last decade;
Africa, had five hundredths of a degree of extra warming in the last few years;
and Australia/New Zealand a tenth of a degree of additional warming over the last few years.
I left out the accompanying graphs, you can find them here. The WUWT fellows also note how this is part of a pattern of “adjusting” recent temperature data upward.
For those who are keeping track (admittedly not easy given the numbers), we have now reached forty-four examples of data manipulation, errors, and other shenanigans from global warming alarmists, and that’s just from what I’ve been able to blog on this subject since Climategate broke in November of 2009, just under three and a half years ago. More to the point, they don’t seem capable of stopping.
In this case, however, it is especially important to remember that the “adjustments” come right smack in the period of the data that has given alarmists their worst headaches: the post-1996 temperature stability. It could very well be that the “solution” is to simply jack up the numbers to make the stability go away…
