Researchers propose bering strait dam to stabilize amoc

A team of Dutch scientists has presented simulations showing that a massive dam across the Bering Strait could help prevent the collapse of the Atlantic Meridional Overturning Circulation. The proposal was outlined at a major geoscience conference in Vienna this month.

Jelle Soons and Henk Dijkstra at Utrecht University ran advanced climate models that indicate closing the strait would strengthen the AMOC, particularly if construction begins by 2050. Their earlier lower-resolution work had produced mixed outcomes, but the new supercomputer runs showed a surprisingly robust recovery in the current system that brings milder conditions to northern Europe.

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.

Arctic Ocean passes tipping point as nitrate levels fall

The Arctic Ocean crossed a tipping point around 2009, according to a new study showing that sea ice loss has sharply reduced nitrate levels in the water.

Scientists identify 3,100 surging glaciers posing flood risks

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.
