EVIDENCE from ice cores1 indicates that concentrations of atmospheric carbon dioxide were lower by about 75 p.p.m. during the Last Glacial Maximum (LGM; ∼18,000 years ago) than during the present interglacial (10,000 years ago to the present). The causes of such large changes in atmospheric CO2 remain uncertain. Using a climate model, Prentice and Fung2 have estimated that there was approximately the same amount of carbon in vegetation and soils during the LGM as there was during the present… 

Extensive loss of past permafrost carbon but a net accumulation into present-day soils

An empirically derived estimate of the carbon stored in permafrost during the Last Glacial Maximum is presented by reconstructing the extent and carbon content of LGM biomes, peatland regions and deep sedimentary deposits, finding that the total estimated soil carbon stock for the LGM northernpermafrost region is smaller than the estimated present-day storage.

Large inert carbon pool in the terrestrial biosphere during the Last Glacial Maximum

During each of the late Pleistocene glacial‐interglacial transitions, atmospheric carbon dioxide concentrations rose by almost 100 ppm. The sources of this carbon are unclear, and efforts to identify

A large increase in the carbon inventory of the land biosphere since the Last Glacial Maximum: constraints from multi-proxy data

Abstract. Atmospheric CO2 increased by about 90 ppm across the transition from the Last Glacial Maximum (LGM) to the end of the preindustrial (PI) period. The contribution of changes in land carbon

The role of shelf nutrients on glacial‐interglacial CO2: A negative feedback

In the past 800 thousand years and before industrialization, the largest variations in atmospheric CO2 concentration (pCO2) occurred in connection with the glacial cycles that characterized Earth's

New estimates of carbon transfer to terrestrial ecosystems between the last glacial maximum and the Holocene

  • Beerling
  • Environmental Science, Geography

Ice core records of atmospheric CO2 show an ≈ 80 ppm rise between the last glacial maximum (LGM) and the mid‐Holocene during a corresponding world‐wide expansion of the terrestrial biomass and

Modeling the dynamics of terrestrial carbon storage since the Last Glacial Maximum

A dynamic global vegetation model (DGVM) was used to simulate global terrestrial carbon storage and stable carbon isotope composition changes for the last 21000 years. A paleoclimate scenario was



The sensitivity of terrestrial carbon storage to climate change

THE high correlation found between atmospheric CO2 concentration and temperature during the past 160,000 years1,2 implicates CO2 as an important driving force behind changes in palaeoclimate. Changes

Soil carbon pools and world life zones

Soil organic carbon in active exchange with the atmosphere constitutes approximately two-thirds of the carbon in terrestrial ecosystems1,2. The relatively large size and long residence time of this

Ice core sample measurements give atmospheric CO2 content during the past 40,000 yr

Recent measurements1,2 on ice samples from Camp Century (Greenland, 77°10'N, 61°08'W), Byrd Station (Antarctica, 80°01'S, 110°31'W) and Dome C (74°40'S, 125°10'E) suggest that during the late part of

Climatic conditions deduced from a 150-kyr oxygen isotope–pollen record from the Arabian Sea

The correlation reported here of oxygen-18 and pollen records from off-shore marine cores1 enables the history of the nearby continental vegetation, which is controlled by climate, to be examined

A pollen record of a complete glacial cycle from lowland Panama

A long pollen record from lowland Panama describes the vegetation during glacial times and proba- bly includes a history of the last 150 000 yr, thus represen- ting a complete glacial cycle. The

Palynological records from northwest African marine sediments: A general outline of the interpretation of the pollen signal

Pollen analysis of over 100 modern surface-sediment samples from the Atlantic off northwest Africa (between 35° and 4° N) has improved the understanding of the relation between modern pollen source
