Atlantisk havsström har försvagats under två decennier, visar studie

Ett omfattande atlantiskt havsströmssystem som reglerar det globala klimatet har saktat ner under nästan 20 års tid. Ny forskning ger direkta bevis på nedgången över ett stort område av Nordatlanten.

Forskare vid University of Miami Rosenstiel School of Marine, Atmospheric and Earth Science ledde studien. De analyserade data från fyra övervakningssystem på havsbotten som sträcker sig från tropikerna till latituderna däremellan. Instrumenten mätte tryck, temperatur och strömmar för att spåra djuphavsflöden under 1 000 meters djup.

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.

A patch of cooling ocean south-east of Greenland, known as the cold blob, is likely caused by a slowdown in the Atlantic Meridional Overturning Circulation, according to new research. The findings add to concerns about potential future climate impacts in Europe and beyond. Scientists remain divided on the exact causes.

Scientists forecast an 80 percent likelihood that an El Niño will form by September, with most models pointing to a moderate event. Some simulations indicate the possibility of a much stronger episode. Global warming is expected to intensify the effects of any such occurrence.

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.

Researchers have created the first global map showing how Earth's deepest mantle is deformed, primarily in regions where ancient subducted tectonic slabs reside. Using over 16 million seismograms, the team confirmed patterns predicted by geodynamic models. The findings, published in The Seismic Record, offer new insights into mantle flow near the core-mantle boundary.
