Ocean surface temperatures reach a new September high
Between 60° south and 60° north, Copernicus reports an average of 21.05°C for September 2026. The previous record for the same month was 20.92°C, set in 2023.

Why some rocks can lock away CO₂ within hours: the chemistry behind faster mineralization
Atomic-scale modelling explains why calcium-bearing olivine can react with CO₂ far more readily than magnesium-rich forms. The calculations reproduce laboratory observations but do not demonstrate industrial carbon storage.

Marsh plants survived extreme wave tests better than expected. Flexibility made the difference
In a large experimental wave flume, waves up to two metres caused about 30% average biomass loss. Stems that bend rather than break could inform nature-based flood protection, but these are not measurements from an actual coastal storm.

At Ischia, tiny shelled seabed organisms shift as seawater pH falls below 7.7
Researchers studying natural CO₂ vents found a clear change in benthic foraminiferal communities near pH 7.7. Applying the local threshold to Mediterranean climate scenarios indicates possible future risks, not observed basin-wide collapse.

For 20 straight years, Arctic summer sea-ice lows have ranked among the 20 smallest on record
On 12 September 2026, Arctic sea ice covered about 4.60 million square kilometres, tied for the tenth-lowest summer minimum in the satellite record, according to NASA and NSIDC.

As the ocean becomes more acidic, phytoplankton change how they use phosphorus
Experiments spanning more than 1,000 generations show that when phosphate is scarce, cells reduce stored phosphorus and build more membranes from lipids that do not require it.

Swiss glaciers lost more than 5% of their remaining ice in a single year
GLAMOS measurements show a loss above 5% in 2026 and nearly 20% over five years. Some smaller glaciers have now disappeared completely.

To take root, mangroves need a break from the waves
A Nature model correctly classified mangrove presence or absence at 78.2% of 394 open-coast sites: what matters is whether young plants get a long enough window of calmer water.

Engineered bacteria speed rock weathering and remove CO2 in a pilot reactor
A modified marine bacterium increased olivine dissolution 2.6-fold. In continuous reactors with more than 4 kg of mineral, the team measured 0.50 g of CO2 removed from air per day — a pilot demonstration, not yet an industrial solution.

Machine learning reconstructs forty years of coral loss at high frequency
Across 223 satellite images from Oman, the method revealed sustained decline and faster average area loss after 2006.
