good one. salient portions below. indeed, more research is needed on AGW before we jump to conclusions. a mild carbon tax for peak oil or budget deficit reduction purposes is warranted however, imo.

What was learned The three U.S. scientists report that their SST reconstruction "shows cooler temperatures between about AD 400 and AD 950 [the Dark Ages Cold Period] than during much of the so-called Medieval Warm Period (about AD 900-1300)." Of this latter period, they say "reconstructed SSTs were warmest from AD 1000 to AD 1250," when "SSTs within error of modern SSTs occurred in the IPWP," as also was the case "during brief periods of the first millennium AD," when the Roman Warm Period held sway. They also report that "SSTs during the Little Ice Age (approximately AD 1550-1850) were variable, and ~0.5 to 1°C colder than modern values during the coldest intervals."
What it means Based on a globally significant SST history, "enabling both a direct comparison of proxy data to the instrumental record and an evaluation of past changes in the context of twentieth century trends," we now have substantial evidence that throughout portions of both the Roman and Medieval Warm Periods, SSTs in the Indo-Pacific Warm Pool were essentially equivalent to those of "the late twentieth century," indicating -- once again -- that there is nothing unusual, unnatural or unprecedented about current air temperatures in this critically important region of the globe.

Well, doesn't Hanson say the 0.4 degrees he found means we are all gonna fry?
But 8000 years ago was the "optimum", giving man the warm weather he needed to be able to do other things besides just try to stay warm and get enough to eat.

Just note the reference :
Oppo, D.W., Rosenthal, Y. and Linsley, B.K. 2009. 2,000-year-long temperature and hydrology reconstructions from the Indo-Pacific warm pool. Nature 460: 1113-1116.
I never saw Nigerian scam published in Nature up to now.
A small quote more : What was learned The three U.S. scientists report that their SST reconstruction "shows cooler temperatures between about AD 400 and AD 950 [the Dark Ages Cold Period] than during much of the so-called Medieval Warm Period (about AD 900-1300)."
