Ice Volume and Sea Level During the Last Interglacial
@article{Dutton2012IceVA, title={Ice Volume and Sea Level During the Last Interglacial}, author={A. Dutton and Kurt Lambeck}, journal={Science}, year={2012}, volume={337}, pages={216 - 219} }
More Melting The last interglacial period, around 125,000 years ago, was 1° to 2°C warmer than the present, and the sea level was thought to be 4 to 6 meters higher. However, Dutton and Lambeck (p. 216), now suggest that sea level was possibly as much as 10 meters above current levels. Such a large excess of seawater would mean that the Greenland and Antarctic ice sheets melted much more than previously assumed, which has implications for how much sea-level rise we should expect with…

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…

Oceanic forcing of penultimate deglacial and last interglacial sea-level rise
- Environmental Science, GeographyNature
- 2020
It is shown that greater subsurface warming induced by the longer period of reduced AMOC during the penultimate deglaciation can explain the more-rapid sea-level rise compared with the last degl Baciation, which contributed to excess loss from the Greenland and Antarctic ice sheets during the LIG, causing global mean sea level to rise at least four metres above modern levels.

Abstract. During the last interglacial period (LIG, ~ 130–115 ka before present, ka = 1000 yr) summer temperatures over Greenland were several degrees higher than today. It is likely that the…

During the Last Interglacial, global mean sea level reached approximately 6 to 9 m above the present level. This period of high sea level may have been punctuated by a fall of more than 4 m, but a…

Abstract. As the most recent warm period in Earth's history with a sea-level stand higher than present, the Last Interglacial (LIG, ∼ 130 to 115 kyr BP) is often considered a prime example to study…
Asynchronous Antarctic and Greenland ice-volume contributions to the last interglacial sea-level highstand

Data show that the Antarctic Ice Sheet dominated particularly high levels of sea-level rise during the early Last Interglacial, and a dual substructure within the first highstand suggests temporal variability in the AIS contributions.
Giant boulders and Last Interglacial storm intensity in the North Atlantic

Data and models are presented showing that, under conditions of higher sea level, historically observed hurricanes can explain geologic features previously interpreted as evidence for more intense Last Interglacial storm activity, and showing that with rising sea levels, cliffs and coastal barriers will be subject to significantly greater erosional energy, even without changes in storm intensity.

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.

It is estimated that eustatic sea level rose to ∼6–13 m above the present-day value in the second half of MIS 11, which suggests that both the Greenland Ice Sheet and the West Antarctic Ice Sheet collapsed during the protracted warm period while changes in the volume of the East Antarctic Ice sheet were relatively minor.
