  1. The Roman Empire existed during a climatic warm period. The “Dark Ages” were relatively cold. The Medieval Warm Period (900 to 1300 AD) was mild enough for Greenland to be quite green. Its relatively benign climate allowed the Viking voyages to happen. The subsequent Little Ice Age (1300 to late C19th) put paid to voyages across North Atlantic.
