For much of the Middle Ages, England's climate differed from that in the 21st century. Between the 9th and 13th centuries England went through the Medieval Warm Period, a prolonged period of warmer temperatures; in the early 13th century, for example, summers were around 1 °C warmer than today and the climate was slightly drier. These warmer temperatures allowed poorer land to be brought into cultivation and for grapevines to be cultivated relatively far north. The Warm Period was followed by several centuries of much cooler temperatures, termed the Little Ice Age; by the 14th century spring temperatures had dropped considerably, reaching their coldest in the 1340s and 1350s. This cold end to the Middle Ages significantly affected English agriculture and living conditions.
