The very long thermometer-reading series from central England (from 1659 on) is of huge interest because it does NOT rely on dubious proxies -- and it shows the 20th century as being unexceptional. I have therefore made a number of allusions to it on this blog.
The Warmists have noted it too and one of them -- Tamino -- has gone to work and made a hockey stick out of it -- using the expected dubious statistical techniques. Tamino is one of the guys mentioned in the hacked CRU emails.
That his results are incredible can I think most convincingly be seen from his plot of the raw data (below)
It is clearly a random walk and any trend up or down is a statistical creation rather than anything real.
As an old FORTRAN-using statistical analysis programmer myself, I am well aware of how you can lie with statistics. That is why it is important to do courses in statistics -- so you can spot it when you are being "had". And much of my academic writing was devoted to pointing out how statistical nullities were being paraded as if they told us something. So it is no surprise to see the statistical jiggery-pokery that has been going on in climate science. Mountains are regularly made out of pimples and if there are not even pimples to be had, one will be created.
