The Medieval Warm Period (MWP) was a time of relatively warm climate in Europe and parts of the Northern Hemisphere, lasting from about 950 to 1250 AD. During this period, temperatures were higher than the average for the preceding centuries, which allowed for increased agricultural productivity and the expansion of settlements in regions like Greenland and Iceland. This warmer climate contributed to significant social and economic changes, including the growth of trade and population. However, the MWP was not uniform globally, as some areas experienced cooler conditions. The period eventually transitioned into the Little Ice Age, which brought colder temperatures and affected agricultural practices.
