Using advanced molecular dating and gene transfer analysis, researchers reconstructed fungi’s ancient lineage, revealing they were crucial in shaping Earth’s first soils and ecosystems.

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 currently keeping deep CO2 trapped below. This stratification effect may be only temporary, as intensifying winds bring deep, carbon-rich water closer to the surface. If mixing increases, the Southern Ocean could begin releasing more CO2 than it absorbs.

New research shows that the rise of Sumer was deeply tied to the tidal and sedimentary dynamics of ancient Mesopotamia. Early communities harnessed predictable tides for irrigation, but when deltas cut off the Gulf’s tides, they faced crisis and reinvented their society. This interplay of environment and culture shaped Sumer’s myths, politics, and innovations, marking the dawn of civilization.

Scientists have uncovered that glaciers can temporarily cool the air around them, delaying some effects of global warming.

The team urges immediate global action to curb emissions and manage dwindling water resources wisely.

Scientists have discovered that El Niño and La Niña could become far more powerful and predictable as the planet warms. By 2050, the tropical Pacific may hit a tipping point, locking ENSO into strong, rhythmic oscillations that synchronize with other global climate patterns. The result could be intensified rainfall extremes and greater risk of “climate whiplash” across multiple continents.

Sea levels are rising faster than at any time in 4,000 years, scientists report, with China’s major coastal cities at particular risk. The rapid increase is driven by warming oceans and melting ice, while human activities like groundwater pumping make it worse. In some areas, the land itself is sinking faster than the ocean is rising. Still, researchers see progress as cities like Shanghai adopt new technologies to stabilize the ground and prepare for the future.

Scientists are taking the once-radical concept of dimming the sun through stratospheric aerosol injection (SAI) seriously, but a Columbia University team warns that reality is far messier than models suggest. Their study reveals how physical, geopolitical, and economic constraints could derail even the best-intentioned attempts to cool the planet. From unpredictable monsoon disruptions to material shortages and optical inefficiencies, every step introduces new risks.

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 supports the entire marine food chain.

The findings reveal a persistent and little-known legacy of industrial dumping that still shapes marine life today.

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 and bass to shift diets and habitats. Using stable isotope analysis, researchers uncovered how the invaders disrupt food webs, broaden dietary overlaps, and destabilize energy flow across the river system. The findings show how a single invasive species can spark cascading ecological consequences.

Tiny ocean microbes called Prochlorococcus, once thought to be climate survivors, may struggle as seas warm. These cyanobacteria drive 5% of Earth’s photosynthesis and underpin much of the marine food web. A decade of research shows they thrive only within a narrow temperature range, and warming oceans could slash their populations by up to 50% in tropical waters.

New research has revealed that East Antarctica’s vast and icy interior is heating up faster than its coasts, fueled by warm air carried from the Southern Indian Ocean. Using 30 years of weather station data, scientists uncovered a hidden climate driver that current models fail to capture, suggesting the world’s largest ice reservoir may be more vulnerable than previously thought.

Once thought to be sailors’ myths, rogue waves gained credibility after a towering 80-foot wall of water struck the Draupner oil platform in 1995.
