Description
July mean temperatures were reconstructed from a pollen profile of the sediments of Toskaljavri (69°12'N, 21°28'E), a tree-line lake in the continental sector of northern Fenoscandia.  The Medieval Warm Period occurred between AD 600 and 1000 and was 0.8°C warmer than the Current Warm Period.
