The Chongce ice cores were dated back to 7 ka BP by a two-parameter flow model (2p model) constrained by the AMS 14C ages. The δ18O measurements were performed at Nanjing University by a Wavelength Scanned Cavity Ring-Down Spectrometer (WS-CRDS, model: Picarro L2120-i), with the analytical uncertainty of less than 0.1‰. Our reconstructed temperature record shows a long-term warming trend until ~2 ka BP, followed by an abrupt change to a relatively cool period until the start of the industrial-era warming. In addition, the record shows that temperatures during the recent decades are almost the highest during the past 7 ka BP, highlighting the unusual warming forced by anthropogenic greenhouse gases.","doi":"10.11888/Paleoenv.tpdc.270911","projection":"GCS_China_Geodetic_Coordinate_System_2000","language":"en","share_type":"online","east":81.14,"west":81.08,"south":35.22,"north":35.27,"scale":null,"crs":null,"filesize":0.02,"share_policy":"a","ts_created":"2020-09-03T22:27:50.406007+08:00","doi_type":"拥有自主知识产权","ts_updated":"2021-09-22T09:48:44.570051+08:00","time_description":"-0.025 ka","datas_group":3,"time_description_en":"7.025 ka","data_format":null,"project":[11],"specials":[],"cite":null,"review_status":5,"review_invite":[],"review_editor":null,"data_sources":null,"temporal_resolution":"10 year < x < 100 year","spatial_resolution":"10m - 100m","license":"Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","fund":[],"subtopics":{"metadata":"d658445d-c0a0-4624-8a56-291e5a58a61f","three_pole":null,"third_pole":null},"username":"hxpang","review_time":null,"protected_duration":null,"protected_describe":null,"is_important":false,"hit_count":1024}
