The medieval Warm Time lasted from about 1000 - 1100 (call it 0C). Then the temperature dropped -0.4C to -0.8C from 1300 - 1850.
This affected Europe as well as eastern North America. The most abundant evidence comes from dendrochronology.
The wood anatomy ("old growth") from those centuries does show some desirable changes in mechanical and elastic properties.
That temperature change is hardly enough for glacier/ice cap formation but the name has certainly stuck around!
