Atlantic Meridional Overturning Circulation is stable under global warming.
Many new studies have been published supporting the hypothesis that the Atlantic Meridional Overturning Circulation (AMOC) is experiencing a slowdown. These studies are based on proxies, climatemodel predictions, or a combination of both. The latest work (1) is only based on predictions. The AMOC is allegedly slowing down at an increased rate because of the Arctic ice melting as predicted by cl...
متن کاملChanges in the Atlantic Meridional Overturning Circulation
Introduction: the concept of the MOC Climate models project a slow down of the Atlantic Meridional Overturning Circulation (MOC) in the twenty-first century. This slow down is expected to affect climate over Europe. In particular, it damps the temperature rise due to the emission of greenhouse gases. The MOC is associated with the thermohaline circulation (ThC), which is the large-scale ocean c...
متن کاملAtlantic Dominance of the Meridional Overturning Circulation
North Atlantic (NA) deep-water formation and the resulting Atlantic meridional overturning cell is generally regarded as the primary feature of the global overturning circulation and is believed to be a result of the geometry of the continents. Here, instead, the overturning is viewed as a global energy–driven system and the robustness of NA dominance is investigated within this framework. Usin...
متن کاملOverlooked possibility of a collapsed Atlantic Meridional Overturning Circulation in warming climate
Changes in the Atlantic Meridional Overturning Circulation (AMOC) are moderate in most climate model projections under increasing greenhouse gas forcing. This intermodel consensus may be an artifact of common model biases that favor a stable AMOC. Observationally based freshwater budget analyses suggest that the AMOC is in an unstable regime susceptible for large changes in response to perturba...
متن کاملReduced interdecadal variability of Atlantic Meridional Overturning Circulation under global warming.
Interdecadal variability of the Atlantic Meridional Overturning Circulation (AMOC-IV) plays an important role in climate variation and has significant societal impacts. Past climate reconstruction indicates that AMOC-IV has likely undergone significant changes. Despite some previous studies, responses of AMOC-IV to global warming remain unclear, in particular regarding its amplitude and time sc...
