Found this interesting, wonder how the weather was in this period. Looking back in history may give us a glimpse into what the current warming will bring.
Greenland
Analyses from central and southern Greenland (see Greenland Stable Isotopes) show that this region did experience a Medieval Warm Period (culminating around ad 1000), a Little Ice Age cool period (ad 1500–1900), and warming to the mid-twentieth century (Alley and Koci, 1990; Cuffey et al., 1994; Dahl-Jensen et al., 1998). In contrast to some other regions of the Arctic, such as northern Alaska and Siberia, Greenland did not have renewed warming through the latter decades of the twentieth century. The Medieval Warm Period was approximately 1 °C warmer than present, and the Little Ice Age 0.6 °C cooler than present, in central Greenland.
