Changes in atmospheric CO2 and its carbon isotopic ratio during the penultimate deglaciation

Jérôme Chappellaz

Climate models show strong links between Antarctic and global temperature both in future and in glacial climate simulations. Past Antarctic temperatures can be estimated from measurements of water stable isotopes along the EPICA Dome C ice core over the pa ...

A 108.83-m ice-core record of atmospheric dust deposition at Mt. Qomolangma (Everest), Central Himalaya

Jérôme Chappellaz

The climate of the last glacial Marine Isotopic Stage 3 (MIS3) period is characterized by strong millennial-scale variability with a succession of Dansgaard-Oeschger events first identified in Greenland ice cores and associated with variations of the Atlan ...

Elsevier BV2010

Since its discovery in Greenland ice cores, the millennial scale climatic variability of the last glacial period has been increasingly documented at all latitudes with studies focusing mainly on Marine Isotopic Stage 3 (MIS 3; 28-60 thousand of years befor ...

Constraint of the CO2 rise by new atmospheric carbon isotopic measurements during the last deglaciation

Jérôme Chappellaz

The suggestion of climatic instability during the last interglacial period (Eem), based on the bottom 10% of the Greenland Ice core Project (GRIP) isotopic profile, has been questioned because the bottom record from the neighboring Greenland Ice Sheet Proj ...

Millennial-scale variability during the last glacial: The ice core record

Jérôme Chappellaz

Water isotope records from the EPICA Dronning Maud Land (EDML) and the NorthGRIP ice cores have revealed a one to one coupling between Antarctic Isotope Maxima (AIM) and Greenland Dansgaard-Oeschger (DO) events back to 50 kyr. In order to explore if this n ...

Expression of the bipolar see-saw in Antarctic climate records during the last deglaciation

Jérôme Chappellaz

The atmospheric CH4 increase from ∼0.7 to 1.68 p.p.m.v. over about the past 300 years which has been documented from analysis of air trapped in ice cores1-4 and from tropospheric measurements (see ref. 5 for example) is attributed to anthropogenic modifica ...

Atmospheric nitrous oxide during the last 140,000years

Jérôme Chappellaz

Typical rapid climate events punctuating the last glacial period in Greenland, Europe and Antarctica are compared to two rapid events occurring under warmer conditions: (i) Dansgaard-Oeschger event 25, the first abrupt warming occurring during last glacial ...

A 70 ka record of explosive eruptions from the TALDICE ice core (Talos Dome, East Antarctic plateau)

Jérôme Chappellaz

The European Project for Ice Coring in Antarctica Dome ice core from Dome C (EDC) has allowed for the reconstruction of atmospheric CO2 concentrations for the last 800,000-years. Here we revisit the oldest part of the EDC CO2 record using different air ext ...

Changing boreal methane sources and constant biomass burning during the last termination

Jérôme Chappellaz

A central issue in climate dynamics is to understand how the Northern and Southern hemispheres are coupled during climate events. The strongest of the fast temperature changes observed in Greenland (so-called Dansgaard- Oeschger events) during the last gla ...

Springer Science and Business Media LLC2008

Atmospheric methane (CH4) records reconstructed from polar ice cores represent an integrated view on processes predominantly taking place in the terrestrial biogeosphere. Here, we present dual stable isotopic methane records [δ13CH4 and δD(CH4)] from four ...
