New studies indicate that stronger winds and warming deep ocean water have triggered a sharp decline in Antarctic sea ice since 2016. Previously expanding, the ice reached a record high in 2014 before plummeting to record lows. Researchers link this shift to wind-driven upwelling of circumpolar deep water.
Warmer Atlantic water originating near Greenland is causing unexpected heating in the deepest parts of the Arctic Ocean. Researchers have found that waters in the Eurasian basin have warmed by 0.074°C since 1990, transferring vast amounts of energy. This development implicates global warming in yet another remote ocean region.

A massive algal bloom has devastated marine life in South Australia over the past eight months, killing around one million animals across more than 550 species. Researchers have identified the culprit as Karenia cristata, a species producing a newly discovered toxin that could spread worldwide. The event, one of the most destructive on record, raises concerns about emerging threats to global oceans.
