“…A second rapid rise in sea level (MWP1B) identified in Barbados coral records 4,71,72,91 is also supported by evidence in the Western Pacific 92,93 and polar Arctic 93 . Rising sea levels during MWP1B have been associated with the melting of the Laurentide, Innuitian, and West Antarctica ice sheets 2,6,72 .…”

Rapid sea-level rise between the Last Glacial Maximum (LGM) and the mid-Holocene transformed the Southeast Asian coastal landscape, but the impact on human demography remains unclear. Here, we create a paleogeographic map, focusing on sea-level changes during the period spanning the LGM to the present-day and infer the human population history in Southeast and South Asia using 763 high-coverage whole-genome sequencing datasets from 59 ethnic groups. We show that sea-level rise, in particular meltwater pulses 1 A (MWP1A, ~14,500–14,000 years ago) and 1B (MWP1B, ~11,500–11,000 years ago), reduced land area by over 50% since the LGM, resulting in segregation of local human populations. Following periods of rapid sea-level rises, population pressure drove the migration of Malaysian Negritos into South Asia. Integrated paleogeographic and population genomic analysis demonstrates the earliest documented instance of forced human migration driven by sea-level rise.

“…These data allow the calculation of global and regional shelf sea expansion rates, coastal retreat rates and land loss rates. The derived metrics we present are essential to assess the effect of a major sea‐level rise pulse on marine and terrestrial biota, their distribution and their genetic make‐up (Cacciapaglia et al, 2021 ; Hanebuth et al, 2011 ; Tian et al, 2020 ). The rasters also allow for identification of the precise timing of land‐bridge flooding, hence establishment of the timing of connectivity between marine gene pools or the timing of separation between terrestrial gene pools.…”

Motivation: Historical changes in sea level caused shifting coastlines that affected the distribution and evolution of marine and terrestrial biota. At the onset of the Last Glacial Maximum (LGM) 26 ka, sea levels were >130 m lower than at present, resulting in seaward-shifted coastlines and shallow shelf seas, with emerging land bridges leading to the isolation of marine biota and the connection of land-bridge islands to the continents. At the end of the last ice age, sea levels started to rise at unprecedented rates, leading to coastal retreat, drowning of land bridges and contraction of island areas. Although a growing number of studies take historical coastline dynamics into consideration, they are mostly based on past global sea-level stands and present-day water depths and neglect the influence of global geophysical changes on historical coastline positions. Here, we present a novel geophysically corrected global historical coastline position raster for the period from 26 ka to the present. This coastline raster allows, for the first time, calculation of global and regional coastline retreat rates and land loss rates. Additionally, we produced, per time step, 53 shelf sea rasters toThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Fairbanks, 1989). The study of these pulses is important as it provides a link between climatic, glacial and oceanic systems (Tian et al, 2020). During the deglaciation period from 16.5 and 8.2 ka BP, global warming triggered the extensive melting of ice sheets, resulting in a eustatic sea-level rise of ~130 m (Lambeck et al, 2014).…”
