A new study suggests Antarctica’s ice sheet hit a climate tipping point about one million years ago, making it far more reactive to temperature and CO2 changes.…

Scientists have finally cracked the mystery behind one of climate change’s strangest fingerprints: while Earth’s surface heats up, the upper atmosphere is rapidly cooling.…

Perceptions of whether government action is succeeding sometimes comes down to different views on what the goal was to start with.

Humans may have returned to Britain far earlier than scientists once believed — not long after the last ice sheet began retreating. New evidence suggests people were already moving into the British Isles around 15,200 years ago, tracking herds of reindeer…

The Toba supereruption 74,000 years ago was so massive it may have plunged Earth into years of darkness and cold, leading some scientists to believe humanity nearly went extinct.…

A colossal underwater volcano in the South Pacific may have revealed a surprising new weapon against climate change. After the 2022 eruption of Hunga Tonga–Hunga Ha’apai, scientists detected enormous amounts of formaldehyde in the atmosphere — a telltale…

Scientists have uncovered a hidden Antarctic threat that could accelerate global sea level rise far faster than expected. Deep beneath floating ice shelves, long channels carved into the ice appear to trap warmer ocean water, dramatically speeding up…

Greenland’s ice sheet is now melting in ways never seen before, with extreme events becoming more frequent, widespread, and intense. Since 1990, meltwater production has skyrocketed, and most record-breaking events have occurred in recent years.…

Deep beneath the Southern Ocean, a quiet but alarming shift is underway: warm water is creeping closer to Antarctica, and scientists are now seeing it clearly for the first time.…

Microplastics are floating through the atmosphere and spreading across the globe, but their true origins have been misunderstood. New research shows land sources emit over 20 times more microplastic particles into the air than the ocean, challenging…

Human societies didn’t just adapt to the planet—they learned to reshape it. From early fire use to today’s global supply chains, our cultural and social innovations have unlocked extraordinary power to transform Earth and improve human life.…

Scientists drilling deep beneath Greenland’s ice have uncovered a startling clue about its past—and future. Evidence shows that the Prudhoe Dome, a major high point of the ice sheet, completely melted around 7,000 years ago during a relatively mild…

That “magic” sponge under your sink may be hiding an environmental downside. While melamine sponges are famous for effortlessly scrubbing away stubborn stains, they slowly break down as you use them—shedding tiny plastic fibers that wash into water…

Scientists have discovered that methane in the open ocean is produced by microbes under nutrient-poor conditions, solving a long-standing mystery. As warming oceans reduce nutrient mixing, these methane-producing microbes may thrive.…

Deep in the Arctic north, drained peatlands—once massive carbon vaults built over thousands of years—are quietly leaking greenhouse gases into the atmosphere.…
