The MWP is generally thought to have occurred from about 950 CE to about 1250 CE, during the European Middle Ages. [2] Some researchers divide the MWP into two phases: MWP-I, which began around 450 CE and ended around 900 CE, and MWP-II, which lasted from about 1000 CE to about 1300 CE; MWP-I is called the early Medieval Warm Period while MWP-II is called the conventional Medieval Warm Period.

In Chapter 7 "Observed Climate Variations and Change", the Executive Summary on page 199 noted that palaeo-climatic evidence indicated surface temperature "fluctuations including the Holocene Optimum around 5,000-6,000 years ago, the shorter Medieval Warm Period around 1000 AD (which may not have been global) and the Little Ice Age which ended ...
Climate models have been quite accurate in projecting the response of global mean temperature to changes in greenhouse gases, primarily carbon dioxide, but also methane, nitrous oxide, and other ...
