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 …

The configuration of Northern Hemisphere ice sheets through the Quaternary
Our understanding of how global climatic changes are translated into ice-sheet fluctuations
and sea-level change is currently limited by a lack of knowledge of the configuration of ice …

Sea-level trends across The Bahamas constrain peak last interglacial ice melt
During the last interglacial (LIG) period, global mean sea level (GMSL) was higher than at
present, likely driven by greater high-latitude insolation. Past sea-level estimates require …

The sensitivity of the Antarctic ice sheet to a changing climate: Past, present, and future
Abstract The Antarctic Ice Sheet (AIS) is out of equilibrium with the current anthropogenic‐
enhanced climate forcing. Paleoenvironmental records and ice sheet models reveal that the …

Sea level and deep-sea temperature reconstructions suggest quasi-stable states and critical transitions over the past 40 million years
Sea level and deep-sea temperature variations are key indicators of global climate changes.
For continuous records over millions of years, deep-sea carbonate microfossil–based δ18O …

A 160,000-year-old history of tectonically controlled methane seepage in the Arctic
The geological factors controlling gas release from Arctic deep-water gas reservoirs through
seabed methane seeps are poorly constrained. This is partly due to limited data on the …
