An analysis of 1516 radiocarbon dates demonstrates that the development of the current circumarctic peatlands began ∼16.5 thousand years ago (ka) and expanded explosively between 12 and 8 ka in concert with high summer insolation and increasing temperatures. Their rapid development contributed to the sustained peak in CH4 and modest decline of CO2 during the early Holocene and likely contributed to CH4 and CO2 fluctuations during earlier interglacial and interstadial transitions. Given the… 

Rapid deglacial and early Holocene expansion of peatlands in Alaska

The results suggest that high summer temperature and strong seasonality during the HTM in Alaska might have played a major role in causing the highest rates of C accumulation and peatland expansion, and an important contribution of these peatlands to the pre-Holocene increase in atmospheric methane concentrations.

Holocene peatland initiation, lateral expansion, and carbon dynamics in the Zoige Basin of the eastern Tibetan Plateau

The Zoige Basin on the eastern Tibetan Plateau has the largest area of highland peatlands in China. However, the development history of these peatlands is still poorly understood. Understanding how

Peatland initiation and carbon dynamics in northeast China: links to Holocene climate variability

Throughout northeast China, the widely distributed peatlands have formed a large carbon (C) pool. However, the relationship between peatland initiation and climate controls is still poorly documented

Factors Affecting Holocene Carbon Accumulation in a Peatland in Southern Ontario

Multi-proxy, medium-resolution Holocene and high-resolution late Holocene records from a southern Ontario ombrotrophic peatland examined factors affecting carbon accumulation. These records include

Cryostratigraphy and Permafrost Evolution in the Lacustrine Lowlands of West‐Central Alaska

The influence of permafrost growth and thaw on the evolution of ice‐rich lowland terrain in the Koyukuk‐Innoko region of interior Alaska is fundamental but poorly understood. To elucidate this

Modelled interglacial carbon cycle dynamics during the Holocene, the Eemian and Marine Isotope Stage (MIS) 11

Abstract. Trends in the atmospheric concentration of CO2 during three recent interglacials – the Holocene, the Eemian and Marine Isotope Stage (MIS) 11 – are investigated using an earth system model



Siberian Peatlands a Net Carbon Sink and Global Methane Source Since the Early Holocene

Interpolar methane gradient (IPG) data from ice cores suggest the “switching on” of a major Northern Hemisphere methane source in the early Holocene, and Russia's West Siberian Lowland represents a long-term carbon dioxide sink and global methane source since theEarly Holocene.

Atmospheric CO2 concentrations over the last glacial termination.

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.

Ice Record of δ13C for Atmospheric CH4 Across the Younger Dryas-Preboreal Transition

Constant δ13CH4 during the rise in methane concentration at the YD-PB transition is consistent with additional emissions from tropical wetlands, or aerobic plant CH4 production, or with a multisource scenario.

Atmospheric Methane and Nitrous Oxide of the Late Pleistocene from Antarctic Ice Cores

A combined record of CH4 measured along the Dome C and the Vostok ice cores demonstrates, within the resolution of the authors' measurements, that preindustrial concentrations over Antarctica have not exceeded 773 ± 15 ppbv during the past 650,000 years.

High‐resolution Holocene N2O ice core record and its relationship with CH4 and CO2

Nitrous oxide (N2O) concentration records exist for the last 1000 years and for time periods of rapid climatic changes like the transition from the last glacial to today's interglacial and for one of

Late Quaternary Atmospheric CH4 Isotope Record Suggests Marine Clathrates Are Stable

Analyses of air trapped in the ice from the second Greenland ice sheet project show stable and/or decreasing δDCH4 values during the end of the Younger and Older Dryas periods and one stadial period, suggesting that marine clathrates were stable during these abrupt warming episodes.

On the origin and timing of rapid changes in atmospheric methane during the Last Glacial Period

We present high resolution records of atmospheric methane from the GISP2 (Greenland Ice Sheet Project 2) ice core for four rapid climate transitions that occurred during the past 50 ka: the end of

Holocene carbon-cycle dynamics based on CO2 trapped in ice at Taylor Dome, Antarctica

A high-resolution ice-core record of atmospheric CO2 concentration over the Holocene epoch shows that the global carbon cycle has not been in steady state during the past 11,000 years. Analysis of

Evidence for an ice‐free Wrangel Island, northeast Siberia during the Last Glacial Maximum

10Be and 26Al surface exposure ages from 22 tors and bedrock samples from Wrangel Island, northeast Siberia, indicate that the East Siberian and Chukchi shelves were ice‐free during the Last Glacial

Changes in the atmospheric CH4 gradient between Greenland and Antarctica during the Holocene

High-resolution records of atmospheric methane over the last 11,500 years have been obtained from two Antarctic ice cores (D47 and Byrd) and a Greenland core (Greenland Ice Core Project). These cores
