Climate adaptation of pre-Viking societies

Understanding how the Viking societies were impacted by past climate variability and they adapted to it has hardly been investigated. Here, we have carried out a new multi-proxy investigation of lake sediments, including geochemical palynological analyses, reconstruct changes in temperature agricultural practices pre-Viking Southeastern Norway during period between 200 1300 CE. The periods 200–300 800–1300 CE warmer than 300–800 period, which is known as “Dark Ages Cold Period”. This cold was punctuated century-scale more temperate intervals, dominated cultivation cereals hemp (before 280 CE, 420–480 580–700 after 800 CE). In between, intervals livestock farming. Our results demonstrate that changed their strategy response Late Antiquity. • Record from same sediment archive. colder SE Norway.
