Researchers have long pinned the blame for a huge pan-European population collapseafter 900BC on climate change. Irish site and climate records from peat bogs show, however, the colder, wetter weather didn’t arrive until at least two generations after the collapse had started.

Ironically we have the Celtic tiger economy to thank for the information used to make these claims, said Dr Katharina Becker, a lecturer in the department of archaeology at University College Cork. The building boom opened up archaeological sites under pipelines, housing and roads. This was used in a study involving UCC, the universities of Bradford and Leeds, and Queen’s University Belfast that is published this evening in the US Proceedings of the National Academy of Sciences. “Our evidence shows definitely that the population decline in this period cannot have been caused by climate change,” said lead author prof Ian Armit of the University of Bradford.
