[edit] Rm graph: why
SEW added the hand-drawn graph. I removed it. As a useful graph for MWP studies, its very poor, indeed quite misleading. It hasonly historical interest.If it belongs anywhere it belongs...on MWP and LIA in IPCC reports. Oh look, its there already. William M. Connolley 09:55:05, 2005-09-03 (UTC).
[edit] End of the MWP
Folks, I've changed mentions of the end of the MWP to be vague on dates, being no more specific than "14th century". This is because what year the MWP ended depends on what criteria you use to define it and where you're measuring; certainly it was still warm most places in 1270 and Northern Europe was in cold winters and short summers by 1350, but points anywhere in between are matters of scholarly opinion ... and the scholars don't agree. More discussion on the LIA discussion page. Jberkus 05:11, 11 September 2005 (UTC)
[edit] anon skepicism
An anon (school board of calgary, it seems) added:
- Some investigators believe that the medieval warming effect was global, and that average global temperatures between the 10th and 14th century were higher than at present, calling into question both the uniqueness of the present global warming trend and the origin of the present trend from human-generated greenhouse gases. That perspective was belittled in the 2001 IPCC report...
and other misc stuff. This is the standard misinterpretation, as is the vitiated bit. The refs added don't seem to useful and the syntax is poor, so if anyone wants them in, its up to you. William M. Connolley 19:22, 4 October 2005 (UTC).
[edit] I'm confused
From the article:
"A radiocarbon-dated box core in the Sargasso Sea shows that sea surface temperature was approximately 1°C cooler than today approximately 400 years ago (the Little Ice Age) and 1700 years ago, and approximately 1°C warmer than today 1000 years ago (the Medieval Warm Period).[11] However, all the reconstructions, as shown above, appear to indicate that it was not."
What is this actually saying, in the context of the rest of the text? Doesn't the last sentence there just cancel everything else out?
Inspector Baynes 22:06, 16 October 2006 (UTC)
- The last sentence is because global warming believers claim that old warming or cooling must have been local events, and there couldn't have been global warming events. (SEWilco 05:08, 17 October 2006 (UTC))

- Its an odd sentence, I hope I didn't write it. To make sense, it would have to say "...it was not global" or somesuch. The easiest thing to do seems to be to remove it William M. Connolley 08:31, 17 October 2006 (UTC)
