Scientists warn of grim new chapter in Earth's climate crisis
An international team of researchers has issued a stark report on the planet's vital signs, declaring that humanity is hurtling toward climate chaos. The analysis of 2025 data reveals record extremes in 22 of 34 tracked indicators, from ocean heat to Antarctic ice loss. While the situation is dire, experts emphasize that bold action can still avert catastrophe.
Scientists uncover nitrogen-fixing bacteria beneath Arctic sea ice
An international team of researchers has discovered that nitrogen-fixing bacteria thrive beneath Arctic sea ice, challenging previous assumptions about nutrient availability in the region. This process, driven by non-cyanobacteria, could boost algae growth and enhance the ocean's CO2 absorption as ice melts. The findings suggest a need to revise models of Arctic ecological changes amid climate warming.
Melting ice strengthens southern ocean carbon barrier
Freshwater from melting ice and increased precipitation is temporarily trapping carbon dioxide in the deep Southern Ocean, countering predictions of a weakening carbon sink. Scientists from the Alfred Wegener Institute explain this stabilizing effect in a new study. However, intensifying winds may soon reverse this protection, potentially releasing stored CO2 into the atmosphere.
Scientists warn earth has hit first climate tipping point
International climate scientists have warned in a new report that tropical coral reefs have already crossed their tipping point due to rising ocean temperatures. The Global Tipping Points Report 2025 highlights risks of cascading failures in other climate systems if global warming exceeds 1.5°C. The findings come ahead of the 30th World Climate Conference in Brazil.
