1. Laser satellites expose a secret Antarctic carbon burst

   A new study shows that the Southern Ocean releases far more carbon dioxide in winter than once thought. By combining laser satellite data with AI analysis, scientists managed to “see” through the polar darkness for the first time. The results reveal a 40% undercount in winter emissions, changing how researchers view the ocean’s carbon balance and its impact on climate models.

2. Deep-sea mining starves life in the ocean’s twilight zone

   Scientists have discovered that deep-sea mining plumes can strip vital nutrition from the ocean’s twilight zone, replacing natural food with nutrient-poor sediment. The resulting “junk food” effect could starve life across entire marine ecosystems.

3. Antarctica’s collapse may already be unstoppable, scientists warn

   Researchers warn Antarctica is undergoing abrupt changes that could trigger global consequences. Melting ice, collapsing ice shelves, and disrupted ocean circulation threaten sea levels, ecosystems, and climate stability. Wildlife such as penguins and krill face growing extinction risks. Scientists stress that only rapid emission reductions can avert irreversible damage.

4. Frozen for 6 million years, Antarctic ice rewrites Earth’s climate story

   Scientists discovered 6-million-year-old ice in Antarctica, offering the oldest direct record of Earth’s ancient atmosphere and climate. The finding reveals a dramatic cooling trend and promises insights into greenhouse gas changes over millions of years.

5. Turning CO2 into clean fuel faster and cheaper

   A new copper-magnesium-iron catalyst transforms CO2 into CO at low temperatures with record-breaking efficiency and stability. The discovery paves the way for affordable, scalable production of carbon-neutral synthetic fuels.
