New research shows ocean currents like the AMOC are weakening, causing coastal flooding in the U.S. Northeast to double since 2005. Sea level rise and currents pose growing infrastructure risks. The ...

Evidence of algae growth and climate simulations reveal the Arctic had seasonal ice, not a permanent ice shelf, for much of the past 750,000 years. These insights challenge long-standing theories. For ...

Antarctic sea ice began to change rapidly in 2015 and 2016. Since then it has remained well below the long-term average.

In recent years, scientists have raised alarms about the potential collapse of key ocean currents in the Atlantic, with significant consequences for global climate and weather patterns. The Atlantic ...

The Arctic’s winter ice extent reached its lowest recorded level in March since satellite monitoring began in 1979.

The Arctic's winter ice extent reached its lowest recorded level in March since satellite monitoring began in 1979. On March 21, 2025, the sea ice cover measured 14.45 million square kilometres ...

The winter growth period for sea ice in the Arctic Ocean is now over, with levels at a record low. The winter ice extent on 21 March 2025 was lower than at any time since continuous satellite ...

Prof Serreze said levels of winter ice this low could compound the decline of the region’s summer sea ice, which is expected to disappear as early as the next decade.

Arctic Sea Ice Winter Maximum At Lowest Level Since Records Began 47 Years Ago Preliminary analysis paints a terrifying picture of the northern polar regions.

Arctic temperatures spiked 36 degrees Fahrenheit, or 20 Celsius, above normal. By the end of the month, sea ice was at its lowest level ever recorded for February.
