The Medieval Warm Period ( MWP ) is generally thought to have occurred from about AD 950 – 1250, during the European Middle Ages.

He proposed that " Evidence has been accumulating in many fields of investigation pointing to a notably warm climate in many parts of the world, that lasted a few centuries around A. D. 1000 – 1200, and was followed by a decline of temperature levels till between 1500 and 1700 the coldest phase since the last ice age occurred.
