Why would you go back to a report that is at least 20 years out of date? - besides, that graph applied to Western Europe.



Well wasn't Western Europe where Napoleon was fighting in 1812??

And PN's graph is of the Northern Hemisphere...


I love history too, but let's get back to the subject at hand - that of Global Temperatures. Regional studies, however fascinating they might be,  have no real relevance with respect to global temperatures.

Northern Hemisphere  temperatures are about 170 times more relevant that Western Europe. You might liike to do the maths.  Western Europe is 1,437,000 square kilometres. The surface area of the World is 510,072,000 square kilometers.

Northern Hemisphere temperatures, while not ideal,  represent a 50% sample. Western European temperatures represent a  0.3% sample. Not only that, but they are clearly different from broader studies.

Have I made my point?


No, because the 'subject at hand' was based on Beertruk's reference to the prolblem Napoleon had with the LIA in1812...
PN's graph was a response to THAT
, and my graph/page was in reply to PN....


That is incorrect, my post was in respect of Beertruk's following comment, which I highlighted, "Im trying to workout why the temperature was hotter in the Middle Ages than it is now".


Yes, precisely...

The reason for the regional variation in temperature in Europe during the Medieval period has probably been discovered.

I referenced this once before :

It makes for interesting reading.

And then there's this, which seems to indicate that the MWP and the LIA where present in Indonesia...
