Forskare föreslår dammbygge i Berings sund för att stabilisera AMOC

Ett team av nederländska forskare har presenterat simuleringar som visar att en massiv damm över Berings sund skulle kunna bidra till att förhindra en kollaps av den atlantiska meridionala omvälvningscirkulationen (AMOC). Förslaget presenterades vid en stor geovetenskaplig konferens i Wien denna månad.

Jelle Soons och Henk Dijkstra vid universitetet i Utrecht körde avancerade klimatmodeller som indikerar att en stängning av sundet skulle stärka AMOC, särskilt om byggnationen påbörjas senast 2050. Deras tidigare arbete med lägre upplösning hade gett blandade resultat, men de nya superdatorkörningarna visade på en överraskande robust återhämtning av det strömningssystem som för med sig mildare förhållanden till norra Europa.

AMOC collapse could release 640 billion tonnes of CO2

A new study warns that a shutdown of the Atlantic Meridional Overturning Circulation (AMOC) would trigger the release of up to 640 billion tonnes of carbon dioxide from the deep Southern Ocean near Antarctica. This feedback effect could raise global temperatures by an additional 0.2°C. Researchers at the Potsdam Institute for Climate Impact Research highlight the risk as humanity's emissions continue to weaken the key ocean current.

New research shows that efforts to reduce air pollution in Europe, North America and East Asia could accelerate weakening of the Atlantic Meridional Overturning Circulation. The ocean current plays a key role in regulating Europe’s climate. Scientists used multiple climate models to assess the impact under continued high greenhouse gas emissions.

Scientists identify 3,100 surging glaciers posing flood risks

17 april 2026 Rapporterad av AI

An international team led by the University of Portsmouth has cataloged more than 3,100 surging glaciers worldwide that can suddenly accelerate, triggering floods, avalanches and other hazards. These glaciers, concentrated in regions like the Arctic and Karakoram Mountains, affect nearly one-fifth of global glacier area despite comprising just 1 percent of all glaciers. Climate change is altering their behavior, increasing unpredictability.
