claim: While the Medieval Warm Period saw unusually warm temperatures in some regions, globally the planet was cooler than current conditions.
evidence: Their reconstruction of the pattern is characterised by warmth over large part of North Atlantic, Southern Greenland, the Eurasian Arctic, and parts of North America which appears to substantially exceed that of the late 20th century (1961–1990) baseline and is comparable or exceeds that of the past decade or two in some regions.
