BACKGROUND Radiocarbon (14C) has long been recognized as providing an essential
dating method covering the past 55,000 years. However, the further role of 14C as a …

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 …

Radiocarbon is an extremely useful carbon cycle tracer and radiometric dating tool. Here,
we review the main principles and challenges involved in the use of radiocarbon in …

Radiocarbon (14C) ages cannot provide absolutely dated chronologies for archaeological
or paleoenvironmental studies directly but must be converted to calendar age equivalents …

The late Miocene offers the opportunity to assess the sensitivity of the Earth's climate to
orbital forcing and to changing boundary conditions, such as ice volume and greenhouse …

No single mechanism can account for the full amplitude of past atmospheric carbon dioxide
(CO2) concentration variability over glacial–interglacial cycles. A build-up of carbon in the …

Using new and published marine fossil radiocarbon (14C/C) measurements, a tracer
uniquely sensitive to circulation and air-sea gas exchange, we establish several …

Proxy-based studies have linked the pre-industrial atmospheric p CO 2 rise of∼ 20 ppmv in
the mid-to late Holocene to an inferred increase in the Southern Ocean overturning and …

Mass extinction at the Cretaceous–Paleogene (K-Pg) boundary coincides with the
Chicxulub bolide impact and also falls within the broader time frame of Deccan trap …

While the ocean's large-scale overturning circulation is thought to have been significantly
different under the climatic conditions of the Last Glacial Maximum (LGM), the exact nature …
