Abstract
Several spatial and temporal characteristics of climate in medieval times are presented. The recent symposium on the climate of the medieval period provided the evidences to support the several conclusions such as an abrupt rise in hemispheric and global temperature occurred in the twentieth century and continues through the first decade of the twenty-first century. Proxy records from mid and high latitudes of the Northern Hemisphere indicate that some 100-yr-long periods of the MCA might be as warm as much of the twentieth century in some regions. Paleodata from the Southern Hemisphere are generally too sparse to draw reliable conclusions about overall temperatures in medieval time. A recently published reconstruction of air temperature for southern South America indicates the presence of a prolonged period of elevated summer temperature occurring in the thirteenth and early fourteenth centuries.
