An assessment of Earth's climate sensitivity using multiple lines of evidence
We assess evidence relevant to Earth's equilibrium climate sensitivity per doubling of
atmospheric CO2, characterized by an effective sensitivity S. This evidence includes …

Intergovernmental Panel on Climate Change (IPCC). Global carbon and other biogeochemical cycles and feedbacks
It is unequivocal that the increases in atmospheric carbon dioxide (CO2), methane (CH4)
and nitrous oxide (N2O) since the pre-industrial period are caused by human activities. The …

Past climates inform our future
BACKGROUND Anthropogenic emissions are rapidly altering Earth's climate, pushing it
toward a warmer state for which there is no historical precedent. Although no perfect analog …

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

On impact and volcanism across the Cretaceous-Paleogene boundary
The cause of the end-Cretaceous mass extinction is vigorously debated, owing to the
occurrence of a very large bolide impact and flood basalt volcanism near the boundary …

Very large release of mostly volcanic carbon during the Palaeocene–Eocene Thermal Maximum
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 …

Spatial patterns of climate change across the Paleocene–Eocene Thermal Maximum
The Paleocene–Eocene Thermal Maximum (PETM; 56 Ma) is one of our best geological
analogs for understanding climate dynamics in a “greenhouse” world. However, proxy data …

Constraining the climate and ocean pH of the early Earth with a geological carbon cycle model
The early Earth's environment is controversial. Climatic estimates range from hot to glacial,
and inferred marine pH spans strongly alkaline to acidic. Better understanding of early …

Lithium isotope evidence for enhanced weathering and erosion during the Paleocene-Eocene Thermal Maximum
The Paleocene-Eocene Thermal Maximum (PETM;~ 55.9 Ma) was a geologically rapid
warming period associated with carbon release, which caused a marked increase in the …
