Ocean acidification may have severe consequences for marine ecosystems; however,
assessing its future impact is difficult because laboratory experiments and field observations …

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

Abstract The Permian–Triassic mass extinction was marked by a massive release of carbon
into the ocean-atmosphere system, evidenced by a sharp negative carbon isotope …

Abstract The Palaeocene–Eocene Thermal Maximum,(PETM) was a global warming event
that occurred about 56 million years ago, and is commonly thought to have been driven …

Humans are continuing to add vast amounts of carbon dioxide (CO2) to the atmosphere
through fossil fuel burning and other activities. A large fraction of the CO2 is taken up by the …

Marine dissolved organic matter (DOM) is a complex mixture of molecules found throughout
the world's oceans. It plays a key role in the export, distribution, and sequestration of carbon …

Atmospheric carbon dioxide concentrations and climate are regulated on geological
timescales by the balance between carbon input from volcanic and metamorphic outgassing …

Abstract Between about 55.5 and 52 million years ago, Earth experienced a series of
sudden and extreme global warming events (hyperthermals) superimposed on a long-term …

Current understanding of the long-term carbon cycle posits that Earth's climate is stabilized
by a negative feedback involving CO 2 consumption by chemical weathering of silicate …

Many palaeoclimate studies have quantified pre-anthropogenic climate change to calculate
climate sensitivity (equilibrium temperature change in response to radiative forcing change) …
