{"title":"Ice-cores, sediments and civilisation collapse: a cautionary tale from Lake Titicaca","description":null,"version":null,"itemType":"journalArticle","abstractNote":"The temptation to equate environmental change with archaeologically observed events is always with us, and matching a climatic downturn with civilisation collapse is perhaps more attractive then ever. The archaeologically observed collapse of the Tiwanaku civilisation in the twelfth century AD has been specifically related to a prolonged drought which would have affected the people’s ability to produce food. However, a careful scrutiny of the data from ice cores and lake sediments persuades the author that no such drought can be inferred: the evidence for climatic change is of quite a different scale and order to the archaeological changes and cannot be used as an explanation of social events.","publicationTitle":"","volume":null,"issue":null,"pages":null,"date":"2005","series":"","seriesTitle":"","seriesText":"","journalAbbreviation":null,"language":null,"DOI":"10.1017/s0003598x00114929","ISSN":null,"shortTitle":"","url":"","archive":"","archiveLocation":"","libraryCatalog":null,"callNumber":"","rights":null,"extra":"","dateAdded":"2026-02-25T14:49:31.369678Z","dateModified":"2026-02-25T14:56:41.698256Z","attachment":null,"id":"620aac0c-6b51-4d9f-ba8f-7a52ffab9170","owner_id":"61bf6ec3-0e84-462c-b0e2-3036131e0196","creators":[{"creatorType":"author","firstName":null,"lastName":"Calaway","id":386,"item_id":"620aac0c-6b51-4d9f-ba8f-7a52ffab9170"}],"study_sites":[{"created_at":"2026-02-25T14:49:31.375369Z","updated_at":"2026-02-25T14:49:31.375370Z","confidence_score":1.0,"context":"Imported from marcos-custom-data","extraction_method":"manual","item_id":"620aac0c-6b51-4d9f-ba8f-7a52ffab9170","validation_score":1.0,"source_type":"manual","section":"other","name":null,"is_manual":true,"location_id":"6d199ae0-d576-444b-bd54-7695d62ab448","id":"3e745148-c087-4f1c-877d-40f8f38be381","location":{"created_at":"2026-02-25T14:49:29.334914Z","updated_at":"2026-02-25T14:49:29.334922Z","latitude":-15.790363240108075,"longitude":-69.43327399503258,"cluster_label":null,"id":"6d199ae0-d576-444b-bd54-7695d62ab448"},"latitude":-15.790363240108075,"longitude":-69.43327399503258}],"tags":[8]}
