So far, the Antarctic Vostok and EPICA Dome C ice cores have provided a composite record of atmospheric carbon dioxide levels over the past 650,000 years. Here we present results of the lowest 200 m of the Dome C ice core, extending the record of atmospheric carbon dioxide concentration by two complete glacial cycles to 800,000 yr before present. From previously published data and the present work, we find that atmospheric carbon dioxide is strongly correlated with Antarctic temperature throughout eight glacial cycles but with significantly lower concentrations between 650,000 and 750,000 yr before present. Carbon dioxide levels are below 180 parts per million by volume (p.p.m.v.) for a period of 3,000 yr during Marine Isotope Stage 16, possibly reflecting more pronounced oceanic carbon storage. We report the lowest carbon dioxide concentration measured in an ice core, which extends the pre-industrial range of carbon dioxide concentrations during the late Quaternary by about 10 p.p.m.v. to 172–300 p.p.m.v. #-------------------- # Publication # Authors: Indermühle, A., E.

The succession of changes through each climate cycle and termination was similar, and atmospheric and climate properties oscillated between stable bounds. Interglacial periods differed in temporal evolution and duration. Atmospheric concentrations of carbon dioxide and methane correlate well with Antarctic air-temperature throughout the record. Present-day atmospheric burdens of these two important greenhouse gases seem to have been unprecedented during the past 420,000 years. #-------------------- # Publication # Authors: Pépin, L., D.

The use of the updated CO2 record presented here and a reexamination of the sea level proxy confirm that the succession of changes has been similar through each of the four marked transitions found at Vostok. Antarctic air temperature and CO2 increase in parallel and almost synchronously, while the rapid warmings over Greenland take place during the last half of their change and coincide with the marked decay in continental ice volume. The Vostok results thus emphasize a fundamental difference between South and North in terms of climate dynamics. Our results confirm the role of CO2 as an important amplifier of the glacial-interglacial warming in the South. It appears also that the marked warming observed at high northern latitudes (lagging behind the CO2 increase by several thousand years) is roughly synchronous with the decay of the northern ice sheets, suggesting a major role of climatic feedback due to this decay. Such a climatic scenario is supported by sensitivity experiments performed with the LLN 2-D model forced by the Northern Hemisphere insolation and CO2. Model results indicate that the decay of the northern ice sheets and the Northern Hemisphere temperature depend primarily on the northern summer insolation. These results, nevertheless, could be affected if mechanisms specific to the Southern Hemisphere appear to play a major role in driving the Northern Hemisphere climate. The model also helps to constrain the time response of ice volume to insolation and CO2 changes. #-------------------- # Publication # Authors: Raynaud, D., J.-M. Barnola, R. Souchez, R.

During this period there were weak, astronomically induced changes in the distribution of solar energy reaching the Earth. The conditions of this orbital climate forcing are similar to those of today's interglacial period, and they rendered the climate susceptible to other forcing--for example, to changes in the level of atmospheric carbon dioxide. Here we use ice-core data from the Antarctic Vostok core to reconstruct a complete atmospheric carbon dioxide record for MIS 11. The record indicates that values for carbon dioxide throughout the interglacial period were close to the Earth's pre-industrial levels and that both solar energy and carbon dioxide may have helped to make MIS 11 exceptionally long. Anomalies in the oceanic carbonate system recorded in marine sediments at the time, for example while coral reefs were forming, apparently left no signature on atmospheric carbon dioxide concentrations. #-------------------- # Publication # Authors: Siegenthaler, U., T.F.

Before 430,000 yr B.P., partial pressure of atmospheric CO2 lies within the range of 260 and 180 parts per million by volume. This range is almost 30% smaller than that of the last four glacial cycles; however, the apparent sensitivity between deuterium and CO2 remains stable throughout the six glacial cycles, suggesting that the relationship between CO2 and Antarctic climate remained rather constant over this interval. #-------------------- # Publication # Authors: Monnin, E., A.

The close correlation between CO2 concentration and Antarctic temperature indicates that the Southern Ocean played an important role in causing the CO2 increase. However, the similarity of changes in CO2 concentration and variations of atmospheric methane concentration suggests that processes in the tropics and in the Northern Hemisphere, where the main sources for methane are located, also had substantial effects on atmospheric CO2 concentrations. #-------------------- # Publication # Authors: Flückiger, J., E.

Little is known, however, about possible N2O variations during the more stable climate of the present interglacial (Holocene) spanning the last 11 thousand years. Here we fill this gap with a high-resolution N2O record measured along the European Project for Ice Coring in Antarctica (EPICA) Dome C Antarctic ice core. On the same ice we obtained high-resolution methane and carbon dioxide records. This provides the unique opportunity to compare variations of the three most important greenhouse gases (after water vapor) without any uncertainty in their relative timing. The CO2 and CH4 records are in good agreement with previous measurements on other ice cores. The N2O concentration started to decrease in the early Holocene and reached minimum values around 8 ka (<260 ppbv) before a slow increase to its preindustrial concentration of ~265 ppbv. #-------------------- # Publication # Authors: Monnin, E., E.J.

These records confirm that the CO2 concentration varied between 260 and 280 ppmv in the Holocene as measured in the Taylor Dome ice core. However, there are differences in the CO2 records most likely caused by mismatches in timescales. Matching the Taylor Dome timescale to the Dome C timescale by synchronization of CO2 indicates that the accumulation rate at Taylor Dome increased through the Holocene by a factor of two and bears little resemblance to the stable isotope record used as a proxy for temperature. This result shows that different locations experienced substantially different accumulation changes, and casts doubt on the often-used assumption that accumulation rate scales with the saturation vapor pressure as a function of temperature, at least for coastal locations. #-------------------- # Funding_Agency # Funding_Agency_Name: European Commission # Grant: #-------------------- # Funding_Agency # Funding_Agency_Name: Swiss National Science Foundation # Grant: #-------------------- # Funding_Agency # Funding_Agency_Name: University of Bern # Grant: #-------------------- # Funding_Agency # Funding_Agency_Name: Swiss Federal Office of Energy # Grant: #-------------------- # Funding_Agency # Funding_Agency_Name: ANR France (Agence nationale pour la Recherche) # Grant: programme PICC #-------------------- # Site_Information # Site_Name: EPICA Dome C # Location: Antarctica # Northernmost_Latitude: -75.1 # Southernmost_Latitude: -75.1 # Easternmost_Longitude: 123.4 # Westernmost_Longitude: 123.4 # Elevation_m: 3240 #-------------------- # Data_Collection # Collection_Name: EDC-Siegenthaler CO2 Luthi2008 Grenoble # Earliest_Year: 426953 # Most_Recent_Year: 392544 # Time_Unit: cal yr BP # Core_Length_m: # Parameter_Keywords: atmospheric gas # Notes: EDC3 gas age timescale applied to CO2 data originally published by Siegenthaler et al. 2005 (NOAA/WDS-Paleo study 2486; https://doi.org/10.25921/zcte-mp31) #-------------------- # Chronology_Information # Chronology: # #-------------------- # Variables # # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/pub/data/paleo/PaST-thesaurus/SKOS/past-thesaurus-v1.0.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Variables format: Short_name what,material,error,units,seasonality,data_type,detail,method,data_format,additional_information # ## Depth depth,,,meter,,ice cores;climate forcing,,,N, ## gas_ageBP gas age,,,calendar year before present,,ice cores;climate forcing,,,N,EDC3_gas_age ## CO2 carbon dioxide,bulk atmosphere,,parts per million,,ice cores;climate forcing,,,N,measured at LGGE in Grenoble; Siegenthaler et al. 2005 # #-------------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: Depth gas_ageBP CO2 2700.77 392544 259.5 2702.97 393579 273.6 2705.17 394560 260.7 2713.97 398086 276.3 2718.37 399722 277.1 2720.57 400504 283.2 2724.97 402000 283.1 2727.17 402731 275.7 2731.57 404181 276.5 2733.77 404927 280.5 2738.17 406368 279.6 2740.37 407093 285.6 2744.77 408600 284.5 2746.97 409383 275.2 2746.97 409383 274.2 2749.17 410206 282.6 2751.37 411071 283.5 2755.77 412962 274.9 2757.97 413948 264.9 2760.17 414963 271.6 2762.37 415955 276.2 2764.57 416965 268.5 2766.77 417979 277.7 2768.97 419013 273.3 2771.17 420107 268.9 2775.57 422374 276.6 2775.57 422374 274.3 2777.77 423491 270.9 2779.97 424604 273.7 2782.17 425678 257.7 2784.37 426953 254.1
