In North America, tree-ring chronologies from the southern Canadian Rockies have provided evidence for higher treelines and wider ring-widths suggesting warmer temperatures and more favorable growing
conditions (Luckman, 1994

700-1350 North American Southwest Desert, South America, Scandinavia, New Zealand and Alaska Analyses of bristlecone pines in the White Mountains of California, showed greater growth was recorded in the 11th and 12th centuries
(Leavitt, 1994). By analyzing 13C/12C ratios in the rings of these trees, it was also found that soil moisture conditions were more favorable in this region during the Medieval Warm Period (Leavitt, 1994). Simultaneous increases in precipitation were additionally found to have occurred in monsoonal locations of the United States desert southwest, where there are indications of increased lake levels from A.D. 700-1350 (Davis, 1994). Other data document vast glacial retreats during the Medieval Warm Period in parts of South America, Scandinavia, New Zealand and Alaska (Grove and Switsur,
1994; Villalba, 1994); and ocean-bed cores suggest global sea surface temperatures were warmer then as well (Keigwin, 1996a, 1996b).

From around 800 A.D. to 1200 or 1300, the globe warmed again considerably and civilization prospered. This warm era displays, although less distinctly, many of the same characteristics as the earlier period of clement weather. Virtually all of northern Europe, the British Isles, Scandinavia, Greenland, and Iceland were considerably warmer than at present. The Mediterranean, the Near East, and North Africa, including the Sahara, received more rainfall than they do today. During this period of the High Middle Ages, most of North America also enjoyed better weather. In the early centuries of the epoch, China experienced higher temperatures and a more clement climate. From Western Europe to China, East Asia, India, and the Americas, mankind flourished as never before.
