A geological perspective on potential future sea-level rise
During ice-age cycles, continental ice volume kept pace with slow, multi-millennial scale, changes in climate forcing. Today, rapid greenhouse gas (GHG) increases have outpaced ice-volume responses, likely committing us to > 9 m of long-term sea-level rise (SLR). We portray a context of naturally precedented SLR from geological evidence, for comparison with historical observations and future pr...
متن کاملSetting the Frames of Expected Future Sea Level Changes by Exploring past Geological Sea Level Records
Past sea level changes are reconstructed by geological means. Present relative sea level changes are recorded by geodetic means. In order to estimate possible future changes in sea level, we have to use the past as a key to the future. Ice melting and water heating are two processes that may lead to a present sea level rise. Both factors are controlled by strict physical processes. After the la...

متن کاملRapid accumulation of committed sea-level rise from global warming.
As carbon emissions and scientific research have accumulated over recent years, climate scientists have come to see global climate change as an increasingly urgent threat (1, 2). In PNAS, Levermann et al. (3) provide a powerful new indicator of danger. When their findings on the long-term sensitivity of global sea level to global warming (∼2.3 m/°C) are put in the context of recent research on ...
متن کاملA geological perspective on sea-level rise and its impacts along the U.S. mid-Atlantic coast
We evaluate paleo-, historical, and future sea-level rise along the U.S. mid-Atlantic coast. The rate of relative sea-level rise in New Jersey decreased from 3.5± 1.0mm/yr at 7.5–6.5 ka, to 2.2± 0.8mm/yr at 5.5–4.5 ka to a minimum of 0.9± 0.4mm/yr at 3.3–2.3 ka. Relative sea level rose at a rate of 1.6± 0.1mm/yr from 2.2 to 1.2 ka (750 Common Era [CE]) and 1.4± 0.1mm/yr from 800 to 1800 CE. Geo...
