The hottest topic for those interested in the earth's carbon cycles is the change in
atmospheric CO2 content between glacial and interglacial time. What caused it? What is its …

Geological, geophysical, and geochemical data support a theory that Earth experienced
several intervals of intense, global glaciation (“snowball Earth” conditions) during …

Abstract Models project that with current CO2 emission rates, the Southern Ocean surface
will be undersaturated with respect to aragonite by the end of this century,,–. This will result …

Historical observations of the concentration of calcium carbonate in global deep sea
sediments are compiled and compared with a new gridded field of seawater CO3 …

During glacial-interglacial cycles, atmospheric CO 2 concentration varied by about 100
ppmv in amplitude. While testing mechanisms that have led to the low glacial CO 2 level …

Feedbacks controlling long-term fluxes in the carbon cycle and in particular atmospheric
carbon dioxide are critical in stabilizing the Earth's long-term climate. It has been …

Deep sea δ 18 O records from benthic foraminifera provide a high-resolution overview of
global ice volume changes over the last three million years, the interval typically referred to …

Sea level cycles recorded by coral terraces at Huon Peninsula (HP) in Papua New Guinea
match rapid climate changes that occurred between 30,000 and 65,000 years ago, seen in …

Geological evidence indicates that grounded ice sheets reached sea level at all latitudes
during two long-lived Cryogenian (58 and≥ 5 My) glaciations. Combined uranium-lead and …

The relationship between atmospheric carbon dioxide (CO2) and climate in the Quaternary
period has been extensively investigated, but the role of CO2 in temperature changes during …
