The global carbon cycle is strongly perturbed by fossil fuel burning leading to atmospheric
CO2 increase. Climatic warming followed by polar ice melting and global sea level rise are …

The best–documented example of rapid climate change that characterized the so–called
'greenhouse world'took place at the time of the Palaeocene–Eocene boundary: introduction …

Proxy reconstructions from marine sediment cores indicate peak temperatures in the first half
of the last and current interglacial periods (the thermal maxima of the Holocene epoch …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO 2 concentrations exceeded 1000 ppm. Global mean …

Weathering of uplifted continental rocks consumes carbon dioxide and transports cations to
the oceans, thereby playing a critical role in controlling both seawater chemistry and climate …

A deep-sea temperature record for the past 50 million years has been produced from the
magnesium/calcium ratio (Mg/Ca) in benthic foraminiferal calcite. The record is strikingly …

Determining the past record of temperature and salinity of ocean surface waters is essential
for understanding past changes in climate, such as those which occur across glacial …

Optimal use of Mg/Ca as a paleotemperature proxy requires establishing calibrations for
different species of foraminifera and quantifying the influence of dissolution. To achieve this …

Calcite and other crystalline polymorphs of CaCO 3 can form by pathways involving
amorphous calcium carbonate (ACC). Apparent inconsistencies in the literature indicate the …

Abstract The Mid‐Pleistocene Transition (MPT), where the Pleistocene glacial cycles
changed from 41 to∼ 100 kyr periodicity, is one of the most intriguing unsolved issues in the …
