From this subfossil wood record, we contextualize the recent magnitude of warming relative to mid-Holocene conditions and reconstruct changes in climate that resulted in regional ice patch growth and reductions in treeline elevation. Specifically, we developed tree-ring based temperature estimates for subalpine treeline and compare and contextualize this record against a mid-Holocene-to-present (ca., 7,000 to 100 cal. BP) transient climate model.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P147TVZU", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.6650b9fcd34e702fe874889f.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_6650b9fcd34e702fe874889f", "keyword": ["Holocene", "Montana", "North America", "USGS:6650b9fcd34e702fe874889f", "United States", "Upper Yellowstone", "Wyoming", "Yellowstone", "biological and physical processes", "biota", "carbon-14 analysis", "climate change", "climatologyMeteorologyAtmosphere", "environment", "snow and ice cover", "time series datasets", "tree ring analysis"], "modified": "2024-12-16T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-112.4188, 42.1222, -108.5470, 46.2669", "theme": ["geospatial"], "title": "Mid-Holocene-to-present Modeled (ca., 7,000 to 100 cal.
