Scientists have issued a stark warning: ocean acidification has crossed planetary boundaries, threatening marine ecosystems and coastal economies. A study published in Global Change Biology reveals that by 2020, ocean acidity had already reached critical levels in some regions, surpassing the safe threshold for marine life. The findings suggest that the rapid decline in ocean ...
Scientists warn that the silently crossing of a crucial threshold by the world’s oceans could destroy marine ecosystems, collapse fisheries, and upset coastal economies. With acidity levels now exceeding safety limits in almost 60% of deep ocean waters 129, a ground-breaking study published in Global Change Biology shows that ocean acidification breached its planetary “danger ...
New research has revealed that the disappearance of sea ice is not only increasing the amount of light entering the ocean but also altering its color. These changes have significant consequences for photosynthetic organisms such as ice algae and phytoplankton, which rely on specific wavelengths of light for survival. Scientists are now investigating how these ...
Recent research has uncovered an overlooked but vital contributor to ocean health—whale urine. While whale feces have long been recognized for their role in nutrient cycles, new findings reveal that urine plays an equally significant part in sustaining marine ecosystems. By transporting essential nutrients across vast regions, whales act as ecosystem engineers, influencing biodiversity and ...
Celebrated as havens of biodiversity, Brazil’s marine protected areas (MPAs) are under strict control meant to guard delicate ecosystems from human impact. Still, a novel study reveals a sneaky invader slipping past these defenses: microplastics. Little plastic particles have crept into even the most pristine, no-take reserves where fishing, tourism, and industrial activity are prohibited ...
Decades have passed since the start of the fight against climate change and the one vital objective remains the same: reducing global warming to 1.5°C higher than it was before the establishment of industries. A very disappointing recent study shows that even if goals this bold are achieved, coastal cities around the globe will still ...
