Hubert Lamb on the Medieval Warm Period, What the Dude Actually Said

"Evidence already cited at various places in this volume suggests that, for a few centuries in the Middle Ages, the climate in most parts of the world regained something approaching the warmth of the warmest postglacial times.

• The northern limit of vineyards with a long history of cultivation lay some 300-500 km north of the limit of commercial vineyards in the 20thC.
• In many parts of England there are traces of medieval tillage far above anything attempted in the present century, even in wartime: up to 350 m above sea level on Dartmoor and 320 m in Northumberland.
• The tree line and upper limits of various crops on the hills of Central Europe were higher than today.
• Mining operations at high levels in the Alps which had long been abandoned were reopened, and water supply ducts were built to take water from points which were subsequently overrun by glaciers and are in some cases still under ice.
• In Central Norway the area of farming spread 100-200m up valleys and hillsides from 800 – 1000 AD, only to retreat just as decisively after 1300 AD.
• The Viking colonies in W and SW Greenland were able to bury their dead sheep in soil that has since been permanently frozen.
• It was also a warm period generally from N Mexico to N Canada, where forest remnants between 25 and 100 km north of the present limit have been found, radio carbon dated between 880 and 1140 AD.
• Holloway (1954) has reported evidence from the forest composition of a warmer climate in South Island, New Zealand, between about 700 AD and 1400 AD, than in the centuries before and after.
• On the coast of East Antarctica, at Cape Hallett, a great modern penguin rookery seems, from radiocarbon dating tests, to have been first colonised between about 400 and 700 AD, presumably during a phase of improving climate, and to have been occupied ever since."....................And how did Michael Mann in 1999 synopsize this article? Like this the fellow did - "Hubert Lamb in 1965, examining mostly evidence from Western Europe, never suggested that the Medieval Warm Period was a global phenomenon." Gee, I wonder what "most parts of the world" Michael Mann doesn't understand.
