Coral reefs, worth an estimated $9.8 trillion a year to humanity, are in far worse shape than previously realized. A massive international study found that during the 2014–2017 global marine heatwave, more than half of the world’s reefs suffered ...
Around 1550, life on Rapa Nui began changing in ways long misunderstood. New research reveals that a severe drought, lasting more than a century, dramatically reduced rainfall on the already water-scarce island, reshaping how people lived, ...
Methane levels in Earth’s atmosphere surged faster than ever in the early 2020s, and scientists say the reason was a surprising mix of chemistry and climate. A temporary slowdown in the atmosphere’s ability to break down methane allowed the gas ...
Forests around the world are quietly transforming, and not for the better. A massive global analysis of more than 31,000 tree species reveals that forests are becoming more uniform, increasingly dominated by fast-growing “sprinter” trees, while ...
Tiny marine plankton that build calcium carbonate shells play an outsized role in regulating Earth’s climate, quietly pulling carbon from the atmosphere and helping lock it away in the deep ocean. New research shows these microscopic engineers are ...
Melting ice from West Antarctica once delivered huge amounts of iron to the Southern Ocean, but algae growth did not increase as expected. Researchers found the iron was in a form that marine life could not easily use. This means more melting ice ...
SAR11 bacteria dominate the world’s oceans by being incredibly efficient, shedding genes to survive in nutrient-poor waters. But that extreme streamlining appears to backfire when conditions change. Under stress, many cells keep copying their DNA ...
Scientists studying ancient ocean fossils found that the Arabian Sea was better oxygenated 16 million years ago, even though the planet was warmer than today. Oxygen levels only plunged millions of years later, after the climate cooled, defying ...
Tiny plastic particles drifting through the oceans may be quietly weakening one of Earth’s most powerful climate defenses. New research suggests microplastics are disrupting marine life that helps oceans absorb carbon dioxide, while also releasing ...
Scientists have identified a newly recognized threat lurking beneath the ocean’s surface: sudden episodes of underwater darkness that can last days or even months. Caused by storms, sediment runoff, algae blooms, and murky water, these “marine ...
Earth’s oceans reached their highest heat levels on record in 2025, absorbing vast amounts of excess energy from the atmosphere. This steady buildup has accelerated since the 1990s and is now driving stronger storms, heavier rainfall, and rising ...
Microscopic ocean algae produce a huge share of Earth’s oxygen—but they need iron to do it. New field research shows that when iron is scarce, phytoplankton waste energy and photosynthesis falters. Climate-driven changes may reduce iron delivery ...

Massive Sargassum blooms sweeping across the Caribbean and Atlantic are fueled by a powerful nutrient partnership: phosphorus pulled to the surface by equatorial upwelling and nitrogen supplied by ...

Researchers discovered that soil microbes in Kansas carry drought “memories” that affect how plants grow and survive. Native plants showed stronger responses to these microbial legacies than ...

Researchers at QUT uncovered how corals reattach to reefs through a three-phase process involving tissue transformation, anchoring, and skeleton formation. Differences among species reveal why some ...

Fungi’s evolutionary roots stretch far deeper than once believed — up to 1.4 billion years ago, long before plants or animals appeared. Using advanced molecular dating and gene transfer analysis, ...

Extinction rates are not spiraling upward as many believe, according to a large-scale study analyzing 500 years of data. Researchers found that species losses peaked about a century ago and have ...

Melting Arctic ice is revealing a hidden world of nitrogen-fixing bacteria beneath the surface. These microbes, not the usual cyanobacteria, enrich the ocean with nitrogen, fueling algae growth that ...

The Southern Ocean absorbs nearly half of all ocean-stored human CO2, but its future role is uncertain. Despite models predicting a decline, researchers found that freshening surface waters are ...

Global scientists warn that humanity is on the verge of crossing irreversible climate thresholds, with coral reefs already at their tipping point and polar ice sheets possibly beyond recovery. The ...

Humanity has reached the first Earth system tipping point, the widespread death of warm-water coral reefs, marking the beginning of irreversible planetary shifts. As global temperatures move beyond ...

Coccolithophores, tiny planktonic architects of Earth’s climate, capture carbon, produce oxygen, and leave behind geological records that chronicle our planet’s history. European scientists are ...

The Amazon has suffered its most destructive fire season in more than two decades, releasing a staggering 791 million tons of carbon dioxide—on par with Germany’s annual emissions. Scientists ...

Marine heatwaves can jam the ocean’s natural carbon conveyor belt, preventing carbon from reaching the deep sea. Researchers studying two major heatwaves in the Gulf of Alaska found that plankton ...

Fungi may have shaped Earth’s landscapes long before plants appeared. By combining rare gene transfers with fossil evidence, researchers have traced fungal origins back nearly a billion years ...

Researchers at KAUST have confirmed that the Red Sea once vanished entirely, turning into a barren salt desert before being suddenly flooded by waters from the Indian Ocean. The flood carved deep ...

Billions of years ago, Earth’s atmosphere was hostile, with barely any oxygen and toxic conditions for life. Researchers from the Earth-Life Science Institute studied Japan’s iron-rich hot ...

Insects are essential for ecosystems, but mounting evidence suggests many populations are collapsing under modern pressures. A new study used cutting-edge genomic techniques on museum specimens to ...

Flathead catfish are rapidly reshaping the Susquehanna River’s ecosystem. Once introduced, these voracious predators climbed to the top of the food chain, forcing native fish like channel catfish ...

UC Santa Barbara researchers project that human impacts on oceans will double by 2050, with warming seas and fisheries collapse leading the charge. The tropics and poles face the fastest changes, and ...

Scientists found that Red Sea corals can endure warming seas but grow much smaller and weaken under long-term heat stress. Though recovery is possible in cooler months, rising global temperatures may ...

Sargassum has escaped the Sargasso Sea and exploded across the Atlantic, forming the massive Great Atlantic Sargassum Belt. Fueled by nutrient runoff, Amazon outflows, and climate events, these ...
