متن کاملGlobal and Local Sea Level During the Last Interglacial: A Probabilistic Assessment
The Last Interglacial (LIG) stage (ca. 130 115 ka), with polar temperatures likely 3 5◦C warmer than today, serves as a partial analogue for low-end future warming scenarios. Multiple indicators suggest that LIG global sea level (GSL) was higher than at present; based upon a small set of local sea level indicators, the Intergovernmental Panel on Climate Change (IPCC)'s Fourth Assessment Report ...
متن کاملDetection of a dynamic topography signal in last interglacial sea-level records
Estimating minimum ice volume during the last interglacial based on local sea-level indicators requires that these indicators are corrected for processes that alter local sea level relative to the global average. Although glacial isostatic adjustment is generally accounted for, global scale dynamic changes in topography driven by convective mantle flow are generally not considered. We use numer...
متن کاملInformation to “ Probabilistic assessment of sea level during the Last Interglacial ”
Nature of the indicators and depositional ranges. The sea level indicators take a variety of forms, including: constructional coral terraces that provide both geomorphological and ecological information; coral biofacies in limestones that provide ecological but not geomorphological information; erosional features such as wave-cut terraces, sea caves, bioerosional notches, and raised beaches; an...
متن کاملQuantification 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 today, and global mean sea level was probably more than 6.6 m higher. However, there are large discrepancies in the estimated contributions to this sea level change from various sources (the Greenland and Antarctic ice sheets and smaller ice caps). Here, we determine probabilistically the likel...
