>>"Pretty much every place in the world was warmer in the Middle Ages, and considerably so, amounting to about 0.6C. To claim it wasn't global is just ignoring the facts."<< This "pretty much every place in the world" from the Middle Ages that you claim is providing your "facts"...is this before most of the world was "discovered" starting in 1492, or a NY Times article from let's say, 1493 or the peer reviewed, Nobel Prize winner on Middle Ages global warming...was that 1460 or 1465. Check with Watts Up, Monckton, Steyn...they will have copies, possibly videos.

The idea didn't originate with Mann. Mann's work on that was published in 2009. This paper from 2003 indicates La Nina-like conditions during the MWP in the central tropical Pacific. There are earlier works indicating similar results. web.archive.org Those two events were a Northern Hemisphere events, and only part of the Northern Hemisphere at that. Past global climate changes had strong regional expression. To elucidate their spatio-temporal pattern, we reconstructed past temperatures for seven continental-scale regions during the past one to two millennia. The most coherent feature in nearly all of the regional temperature reconstructions is a long-term cooling trend, which ended late in the nineteenth century. At multi-decadal to centennial scales, temperature variability shows distinctly different regional patterns, with more similarity within each hemisphere than between them. There were no globally synchronous multi-decadal warm or cold intervals that define a worldwide Medieval Warm Period or Little Ice Age, but all reconstructions show generally cold conditions between AD 1580 and 1880, punctuated in some regions by warm decades during the eighteenth century. The transition to these colder conditions occurred earlier in the Arctic, Europe and Asia than in North America or the Southern Hemisphere regions. Recent warming reversed the long-term cooling; during the periodAD 1971–2000, the area-weighted average reconstructed temperature was higher than any other time in nearly 1,400 years. http://www.nature.com/ngeo/journal/v6/n5/full/ngeo1797.html
