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.
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 el niño may become more predictable and intense
A new study reveals that the El Niño-Southern Oscillation (ENSO) could intensify and synchronize with other climate patterns due to global warming, potentially leading to more extreme weather by mid-century. Researchers predict a tipping point around 2050 in the tropical Pacific, shifting ENSO from irregular cycles to strong, rhythmic oscillations. This change may heighten risks of rainfall extremes and climate whiplash in regions like Southern California and the Iberian Peninsula.
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.
