After that time, global temperatures dropped until the "Little Ice Age," bottoming out somewhere between AD 1450 and 1850.
In the 1960s, Hubert Lamb generalised from historical documents and temperature records of central England to propose a Medieval Warm Period in the North Atlantic region, followed by Little Ice Age. This was discussed in the IPCC First Assessment Report with cautions that the medieval warming might not have been global.
