In the 1995 edition of his Climate, History and the Modern World, Lamb expressed doubts that the MWP was world-wide. Specifically, it did not seem to have occurred in the Far East. On the other hand, he did think that the LIA was a global phenomenon. Subsequent work that I’ve looked at (based on references cited in the 2011 NIPCC report) indicate that Lamb was being too cautious, since there is clear evidence now from China (and elsewhere) for higher temperatures in the early Medieval period.

lowpassmin.m goes a bit wild if end data is not removed:

http://www.climateaudit.info/data/uc/lpcet.png

code:

load c2010.dat % http://hadobs.metoffice.com/hadcet/
c=c2010(:,end);
X=NaN(352,252);
for i=101:352
x=lowpassmin(c(1:i),1/50); % smooth from year c2010(1,1) to c2010(i,1)
X(1:i,i-100)=x;
end

close all
figure
plot(c2010(:,1),X) % plot all smooths
hold on
kk=plot(c2010(:,1),X(:,end),’k') % plot 1659 to 2010 smooth in bold
set(kk,’LineWidth’,3)

To see why this happens, see comments in http://climateaudit.org/2008/09/02/uc-on-mann-smoothing/

Tried to update this with new HadCET ( http://hadobs.metoffice.com/hadcet/ ), but it gets too cold:

Is “minimum roughness” dead now?
