With polar temperatures ∼3–5 °C warmer than today, the last interglacial stage (∼125 kyr ago) serves as a partial analogue for 1–2 °C global warming scenarios. Geological records from several sites indicate that local sea levels during the last interglacial were higher than today, but because local sea levels differ from global sea level, accurately reconstructing past global sea level requires an integrated analysis of globally distributed data sets. Here we present an extensive compilation of… 

Quantification of the Greenland ice sheet contribution to Last Interglacial sea level rise

During the Last Interglacial period ( 130-115 thousand years ago) the Arctic climate was warmer than to- day, and global mean sea level was probably more than 6.6 m higher. However, there are large

High interstadial sea levels over the past 420ka from the Huon Peninsula, Papua New Guinea

The history of sea level across the Quaternary is essential for assessing past and future climate. Global sea-level reconstructions are typically derived from oxygen isotope curves, but require

Ice Volume and Sea Level During the Last Interglacial

Data indicate that global (eustatic) sea level peaked 5.5 to 9 meters above present sea level, requiring smaller ice sheets in both Greenland and Antarctica relative to today and indicating strong sea-level sensitivity to small changes in radiative forcing.

Sea-level trends across The Bahamas constrain peak last interglacial ice melt

This work compares data and existing LIG sea-level data across the Bahamian archipelago with a suite of 576 GIA model predictions and suggests that LIG GMSL may be lower than previously assumed.

No evidence from the eastern Mediterranean for a MIS 5e double peak sea-level highstand

Abstract To understand past and future sea-level variability, it is important to know if during an interglacial the eustatic sea level is constant or oscillates by several meters around an average

Last interglacial sea levels within the Gulf of Mexico and northwestern Caribbean Sea

Abstract. During the last interglacial (LIG) the volume of additional water in the world's oceans was large enough to raise global sea levels about 6–9 m higher than present levels. However, LIG sea

Paleo Constraints on Future Sea-Level Rise

Sea-level rise predicted for the twenty-first century and beyond will become increasingly hazardous to coastal populations, economies, static infrastructure, and ecosystems. Accurately predicting the



Sea-level fluctuations during the last glacial cycle

A hydraulic model of the water exchange between the Red Sea and the world ocean is used to derive the sill depth—and hence global sea level—over the past 470,000 years, finding that sea-level changes of up to 35 m occurred, coincident with abrupt changes in climate.

Quaternary climates and sea levels of the u.s. Atlantic coastal plain.

The composite sea level chronology for the Atlantic Coastal Plain is inconsistent with independent estimates of eustatic sea level positions during interglacial intervals of the last 200,000 years and Hydroisostatic adjustment from glacial-interglacial sea level fluctuations, lithospheric flexure, and isostatic uplift from sediment unloading due to erosion provide possible mechanisms to account for the discrepancies.

Rapid fluctuations in sea level recorded at huon peninsula during the penultimate deglaciation

The early (about 140,000 years ago) start of the penultimate deglaciation, well before the peak in insolation, is consistent with the Devils Hole chronology.

Substantial contribution to sea-level rise during the last interglacial from the Greenland ice sheet

It is concluded that the high sea level during the last interglacial period most probably included a large contribution from Greenland meltwater and therefore should not be interpreted as evidence for a significant reduction of the West Antarctic ice sheet.

Penultimate Deglacial Sea-Level Timing from Uranium/Thorium Dating of Tahitian Corals

Results from fossil corals found in Tahiti indicate that sea level began to rise when insolation at 65° North latitude was near a minimum, not after it had begun to rise, as predicted by the Milankovitch theory, and that it fluctuated on a millennial time scale during deglaciation.

The Last Interglacial sea level change: new evidence from the Abrolhos islands, West Australia

U-series ages measured by thermal ionisation mass spectrometry (TIMS) are reported for a Last Interglacial (LI) fossil coral core from the Turtle Bay, Houtman Abrolhos islands, western Australia. The

Emergent Marine Record and Paleoclimate of the Last Interglaciation along the Northwest Alaskan Coast

Abstract The last interglacial high sea-level stand, the Pelukian transgression of isotope substage 5e, is recorded along the western and northern coasts of Alaska by discontinuous but clearly

Milankovitch Forcing of the Last Interglacial Sea Level

The sea-level results are shown to be consistent with climate models, and indicate that a fuller understanding of the Milankovitch-climate connection requires consideration of fields other than just insolation forcing at 65�N.
