I’m sorry, I meant ‘Medieval Climatic Anomaly’
I left the following comment at http://tenthmedieval.wordpress.com/2010/04/05/im-sorry-i-meant-medieval-climatic-anomaly/
I think it deserves an answer.
Here are some references about the medieval warm period which show it was not local.
You could also check out the links on my blog
http://www.rogerfromnewzealand.wordpress.com about Greenland, Switzerland, Greenland ice cores and the US on my blog.
Well here is an anecdotal one about Spain.
Of course the medieval warm period shows up in other literature as well, such as a New Zealnd study
or if you want to read “Grove, J.M. 988:The little ice age.by methuen.
Warm periods are well documented by other cultures eg
where the historical history of China’s climate is examined.
Medieval warming and earlier periods are even suggested in the Antarctic Ice core project.
and the Pacific warm pool.
I could go on.
Oops did someone say localised?
Of course the MWP is only one of a number of warming (warmer than the present) which have occured in historical times.
Lets not forget that during the Holocene period, the Sahara was lush and fertile. Do some reading on that maybe? http://www.jstor.org/pss/2997337 is a good start.
Its a little irrelevant but I like this video clip where Obama is laughed at when mentioning climate change in speech http://www.hootervillegazette.com/climatejoke.html
