The most recent deglaciation of the North American Ice Sheet Complex (NAISC: comprising
the Innuitian, Cordilleran, and Laurentide ice sheets) offers a broad perspective from which …

A database of surface Antarctic snow isotopic composition is constructed using available
measurements, with an estimate of data quality and local variability. Although more than …

Reproducible climate reconstructions of the Common Era (1 CE to present) are key to
placing industrial-era warming into the context of natural climatic variability. Here we present …

Abstract The Antarctic Vostok ice core provided compelling evidence of the nature of climate,
and of climate feedbacks, over the past 420,000 years. Marine records suggest that the …

The stable carbon isotope ratio of atmospheric CO2 (δ13Catm) is a key parameter in
deciphering past carbon cycle changes. Here we present δ13Catm data for the past 24,000 …

• The sustained rate of increase over the past century in the combined radiative forcing from
the three well-mixed greenhouse gases carbon dioxide (CO2), methane (CH4), and nitrous …

The climate sensitivity of the Community Climate System Model version 3 (CCSM3) is
studied for two past climate forcings, the Last Glacial Maximum (LGM) and the mid …

The Milankovitch theory of climate change proposes that glacial–interglacial cycles are
driven by changes in summer insolation at high northern latitudes. The timing of climate …

The deuterium excess (d) of precipitation is widely used in the reconstruction of past climatic
changes from ice cores. However, its most common interpretation as moisture source …

We present simulations of water‐stable isotopes from the LMDZ general circulation model
(the LMDZ‐iso GCM) and evaluate them at different time scales (synoptic to interannual) …
