Right here is the summary of the paper not paywalled:
Utilizing transient local weather forcing based mostly on simulations from the Alfred Wegener Institute Earth System Mannequin (AWI-ESM), we simulate the evolution of the Greenland Ice Sheet (GrIS) from the final interglacial (125 ka, kiloyear earlier than current) to 2100 AD with the Parallel Ice Sheet Mannequin (PISM). The influence of paleoclimate, particularly Holocene local weather, on the current and future evolution of the GrIS is explored. Our simulations of the previous present shut settlement with reconstructions with respect to the latest timing of the peaks in ice quantity and the local weather of Greenland. The utmost and minimal ice quantity at round 18–17 ka and 6–5 ka lag the respective extremes in local weather by a number of thousand years, implying that the ice quantity response of the GrIS strongly lags climatic modifications. Provided that Greenland’s local weather was getting colder from the Holocene Thermal Most (i.e., 8 ka) to the Pre-Industrial period, our simulation implies that the GrIS skilled development from the mid-Holocene to the commercial period. Resulting from this background development, the GrIS nonetheless good points mass till the second half of the twentieth century, although anthropogenic warming begins round 1850 AD. That is additionally in settlement with observational proof displaying mass lack of the GrIS doesn’t start sooner than the late twentieth century. Our outcomes spotlight that the current evolution of the GrIS is just not solely managed by the latest local weather modifications, however can also be affected by paleoclimate, particularly the comparatively heat Holocene local weather. We suggest that the GrIS was not in equilibrium all through the whole Holocene and that the gradual response to Holocene local weather must be represented in ice sheet simulations with a purpose to predict ice mass loss, and due to this fact sea stage rise, precisely.
