Global Climate Change

The Medieval Temperature Optimum was a warm period in the Northern Atlantic region between AD 950 to 1250 where temperatures raised above the normal temperatures for at least a century. Researchers explained the temperature change by locating dry sediments that are associated with that time and also by observing the migrations of the Native Americans during that time. The Little Ice Age period occurred after The Medieval Temperature Optimum from about 1350 AD to 1850, the temperature decline was not significant but the temperatures were below average for awhile. It was almost like a very long winter year round, the great artist back in that time depicted this in many of their paintings.
