John; Stopka, Cody; Parker, Dusty; Jiménez-Moreno, Gonzalo; Shuman, Bryan # Published_Date_or_Year: 2015 # Published_Title: Medieval Warming initiated exceptionally large wildfire outbreaks in the Rock Mountains # Journal_Name: Proceedings of the National Academy of Sciences # Volume: # Issue: # Pages: # Report Number: # DOI: 10.1073/pnas.1500796112 # Abstract: Many of the largest wildfires in US history burned in recent decades, and climate change explains much of the increase in area burned. The frequency of extreme wildfire weather will increase with continued warming, but many uncertainties still exist about future fire regimes, including how the risk of large fires will persist as vegetation changes. Past fire-climate relationships provide an opportunity to constrain the related uncertainties, and reveal widespread burning across large regions of western North America during past warm intervals. Whether such episodes also burned large portions of individual landscapes has been difficult to determine, however, because uncertainties with the ages of past fires and limited spatial resolution often prohibit specific estimates of past area burned. Accounting for these challenges in a subalpine landscape in Colorado, we estimated century-scale fire synchroneity across 12 lakesediment charcoal records spanning the past 2,000 y. The percentage of sites burned only deviated from the historic range of variability during the Medieval Climate Anomaly (MCA) between 1,200 and 850 y B.P., when temperatures were similar to recent decades. Between 1,130 and 1,030 y B.P., 83% (median estimate) of our sites burned when temperatures increased ~0.5 degrees C relative to the preceding centuries. Lake-based fire rotation during the MCA decreased to an estimated 120 y, representing a 260% higher rate of burning than during the period of dendroecological sampling (360 to -60 y B.P.). Increased burning, however, did not persist throughout the MCA. Burning declined abruptly before temperatures cooled, indicating possible fuel limitations to continued burning. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Science Foundation # Grant: BCS-0845129 #--------------------------------------- # Site Information # Site_Name: Hinman Lake # Location: Colorado # Country: United States of America # Northernmost_Latitude: 40.771 # Southernmost_Latitude: 40.771 # Easternmost_Longitude: -106.827 # Westernmost_Longitude: -106.827 # Elevation: 2501 #--------------------------------------- # Data_Collection # Collection_Name: USPHN001 CHAR # First_Year: 1738 # Last_Year: -62 # Time_Unit: cal yr BP # Core_Length: # Notes: #--------------------------------------- # Chronology: # Age model generated with the R package Bchron # Depth (cm) Lab Number Material Age (14C BP or 210Pb age +/-1Sigma ) # 11 Sediment surface # 15-16 St. Croix W.R.S Bulk sediment (210Pb) -28.2+/-0.68 # 19-20 St. Croix W.R.S Bulk sediment (210Pb) 3+/-0.94 # 23-24 St. Croix W.R.S Bulk sediment (210Pb) 62.6+/-2.57 # 25-26 St. Croix W.R.S Bulk sediment (210Pb) 131.5+/-12.22 # 69-70 UCIAMS-115861 Charcoal 1085+/-15 # 88-89 UCIAMS-138634 Charcoal and needle 1315+/-20 # 94-96 UCIAMS-115860 Charcoal 1820+/-15 # #--------------------------------------- # Variables # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) ## depth-cm-top depth,,,cm,,,top depth,,N ## depth-cm-bottom depth,,,cm,,,bottom depth,,N ## age-calBP-top age,,,calendar years BP,,Fire History,top of sample,,N ## age-calBP-bottom age,,,calendar years BP,,Fire History,top of sample,,N ## vol-wetsed volume,wet sediment,,ml,,Fire History,used for charcoal counts,,N ## char>125um charcoal,,,counts,,Fire History,>125um,,N #------------------------ # Data # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing Value: n/a depth-cm-top depth-cm-bottom age-calBP-top age-calBP-bottom vol-wetsed char>125um 11 12 -62 -54 1 4 12 13 -54 -45 1 4 13 14 -45 -37 1 3 14 15 -37 -29 1 3 15 16 -29 -21 1 1 16 17 -21 -14 1 2 17 18 -14 -6 1 3 18 19 -6 2 1 2 19 20 2 17 1 2 20 21 17 32 1 4 21 22 32 47 1 3 22 23 47 63 1 3 23 24 63 96 1 2 24 25 96 130 1 10 25 26 130 158 1 14 26 27 158 180.5 1 43 27 28 180.5 204 1 42 28 29 204 223 1 16 29 30 223 242 1 38 30 31 242 261 1 4 31 32 261 280 1 2 32 33 280 298 1 2 33 34 298 315 1 1 34 35 315 333.5 1 5 35 36 333.5 351 1 5 36 37 351 370 1 2 37 38 370 388 1 4 38 39 388 404 1 12 39 40 404 424 1 2 40 41 424 443 1 3 41 42 443 461.5 1 8 42 43 461.5 481.5 1 13 43 44 481.5 499.5 1 13 44 45 499.5 515 1 7 45 46 515 534 1 10 46 47 534 554 1 6 47 48 554 574.5 1 4 48 49 574.5 592 1 3 49 50 592 610 1 3 50 51 610 629 1 3 51 52 629 646 1 5 52 53 646 666 1 41 53 54 666 688 1 6 54 55 688 708 1 3 55 56 708 726 1 7 56 57 726 744 1 12 57 58 744 764 1 10 58 59 764 782 1 8 59 60 782 800 1 14 60 61 800 819.5 1 30 61 62 819.5 840 1 7 62 63 840 857 1 8 63 64 857 877 1 10 64 65 877 898 1 4 65 66 898 918 1 16 66 67 918 936 1 25 67 68 936 955.5 1 12 68 69 955.5 977 1 7 69 70 977 1002 1 44 70 71 1002 1021 1 11 71 72 1021 1039 1 11 72 73 1039 1054 1 24 73 74 1054 1067 1 5 74 75 1067 1081 1 3 75 76 1081 1093 1 5 76 77 1093 1108 1 3 77 78 1108 1122 1 10 78 79 1122 1136 1 12 79 80 1136 1150 1 19 80 81 1150 1164 1 39 81 82 1164 1178.5 1 13 82 83 1178.5 1194 1 15 83 84 1194 1207 1 22 84 85 1207 1222 1 54 85 86 1222 1237 1 31 86 87 1237 1253 1 23 87 88 1253 1277 1 26 88 89 1277 1351 1 47 89 90 1351 1430 1 42 90 91 1430 1509 1 23 91 92 1509 1588 1 24 92 93 1588 1671 1 17 93 94 1671 1738 1 24
