During the Paleocene-Eocene Thermal Maximum (PETM),∼ 56 Mya, thousands of
petagrams of carbon were released into the ocean-atmosphere system with attendant …

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 …

Ocean ecosystems have responded and will continue to respond to climate changes of
different rates, magnitudes, and durations (virtually certain). Human societies depend on …

Climate change is expected to modify ecological responses in the ocean, with the potential
for important effects on the ecosystem services provided to humankind. Here we address the …

• 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 …

Marine barite (BaSO4) is produced in the water column in association with decaying organic
matter; its distribution in the water column and in core-top sediments closely corresponds …

Dramatic warming and upheaval of the carbon system at the end of the Paleocene Epoch
have been linked to massive dissociation of sedimentary methane hydrate. However, testing …

Extreme global warmth and an abrupt negative carbon isotope excursion during the
