They all need to be averaged out to give a global temperature or at the very least a hemispheric temperature. Manns "hockey stick" graph is based on such global averages and are not simply figures for odd regions of the world unlike the studies you higlight. Yes bits of Western Europe or China might have been warmer in the mediaeval warm period - others bits of the world were not and on average neither was the world.
I get the feeling that there really is no further point in me continuing in this discussion the overwhelming body of evidence collected by climate scientist points in one direction, you can select odd little bits of data to support your own agenda or indeed any hypothesis and that is all you are doing. |
Cherry picking? The papers from China are just 2 of the 33 that I have to hand. Similar research is available globally.
Manns hockey stick is based on data collected from car-parks and roof tops and ohter dubious places.Have you ever heard of the ice fairs held on the Thames ? Is that an odd bit of data?
I don't have an agenda,but I do have an aversion to politically inspired numpties trying to scare the hell out of people with bad science.

Do you mean the scientists allied to the IPCC? All 2500 of them? There are some 400,000 science grads. in India each year,just to put a perspective on the numbers game. And make no mistake about it, not all of those attached to the IPCC are climate specialists either.You are no doubt aware that there is satillite data in the public realm showing that the global temperatures have been dropping?
I will consider Manns output again when I recieve a satisfactory explaination of the missing series from his latest efforts.
Which fairy tale is correct,Dickens and the ice fairs or Mann and the hockey stick ? Dickens is by far the better writer,maybe I am biased.
