Proxy records of climate from blanket mires: evidence for a Dark Age (1400 BP) climatic deterioration in the British Isles

Abstract

Pioneer studies of peat stratigraphy in Scandinavia led to division of the Holocene into climatic periods, and though this scheme was later re-evaluated and partly rejected, studies in Denmark and England have demonstrated a link between the stratigraphy of lowland raised mires and past climatic change. In a new study, radiocarbon dating of changes in the degree of humification of peat from blanket mires in the British Isles appears to show a change to wetter conditions around 1400 BP. -from Authors
