I was going through the GISS map site and saw what an exrtaordinary year the United States is going through and yet the average over the globe isn't that high. I invite anyone to look at the color maps and zonal mean graph for each of the six months of this year. To keep the same comparison as I saw just change the month and nothing else for the different months of the year of 2012. There are some incredibly warm areas in the northern lattitudes compared to the base period 1951-1980.

GISS came in as the 13th warmest for July 2012. On AQUA it looks like as if UAH should come out with a similar anomaly as last month. 2012 has not been warm at all when compared to the last 15 years.

Wayne you state that "You mean it is like the MWP where there was a significant anomoly in the north Atlantic basin, but not so much evidenced in other areas?" which is kinda correct but we go back to the ANDRILL results and they state that they have evidence for the MWP in their core samples and are going to be investigating it further in one of their funding reports that I linked to before.

If this signal is correct then the MWP was a global event with variations in the southern hemisphere and it will be interesting to see what they conclude when they get to drilling again.

To select a handful of papers and represent it as cast iron proof that some time in the medieval period was warmer then now seems to me to be dishonest when so many lines of evidence do not support that bold assertion.

Spot, the problem with it is when you have the guys and gals of ANDRILL drilling into the sea bed from above the sea ice and they make a statement like this in their financial review like

"Over 4000 samples from snow sections and ice cores have been analysed for isotopes and
geochemical elements. These indicators of change are providing information on the age of the
snow/ice, air temperature, degree of windiness, extent of sea ice and ocean turbulence. Preliminary
results have identified the Little Ice Age, a cold spell from 1400 to 1850 AD mostly found in
Northern Hemispheric records, when temperatures were ~1oC cooler than today. The record also
identified potentially the termination of the Mediaeval Warm Period (800-1400 AD) when
temperatures were 1 to 2oC warmer and storms more prevalent than now."

ANTARCTIC RESEARCH CENTRE
VICTORIA UNIVERSITY OF WELLINGTON
REPORT FOR 2008, WITH OUTLINE FOR 2009 AND BEYOND

They would be foolish to say anything like this if it were not true, they also reveal a few other things in the report as well as their research as a whole. There is another report that clearly states part of the 2009 funding will be put to looking into the MWP signal.

Now this is in essence as far from the northern hemisphere as you can get, being at the south pole, showing if they have signals in their cores that show it happened that it is a global event, with variation in the southern hemisphere because it is not as clear in sites from other studies as it is in the northern hemisphere.

Other studies support different conclusions;




Arctic Ice extent is to a large part dependent on temperature, in common with most reconstructions it does seem to indicate a warmer period in the middle ages followed by a cooling in the early modern period. but recently we see a a massive drop off of sea ice extent, what could possibly be causing that and what are the implications?
