Credit: PixabayThe levels of dissolved oxygen in the world's water bodies are dropping quickly, and scientists consider this a major threat to Earth's life support system.Much like atmospheric oxygen is crucial for animals, dissolved oxygen (DO) is key for the health of aquatic ecosystems, whether in freshwater or marine environments. Given that billions of...

Credit: PixabayThe University of Leeds has revealed the genuine climate impact of long-distance passenger travel in recent research.Although trips over 50 miles (one way) account for less than 3% of all travel by UK residents, they contribute 70% of all passenger travel-related carbon emissions. This disparity is even more pronounced with international travel, which...
Credit: PixabayWhile trees and green spaces are often celebrated for their contributions to cleaner air and a healthier environment, recent research has highlighted a surprising drawback: they can also be significant sources of air pollution. A study mapping volatile organic compounds (VOCs) over Los Angeles revealed that botanical emissions, particularly from trees, are responsible...
Credit: PixabayRecently, over 70 wildfires burned simultaneously in Greece. In early 2024, Chile experienced its worst wildfire season ever, resulting in over 130 fatalities. Last year, Canada endured record-breaking wildfires from March to November, and in August, flames ravaged Maui in Hawaii. And the list continues.Watching the news, it seems like catastrophic wildfires are...

Since 2021, eight eruptions have occurred, driven by a shallow magma reservoir approximately 10 kilometers wide and located just 9-12 kilometers beneath the surface, according to new research.Geologist Valentin Troll from Uppsala University in Sweden, who led...
Scientists have proposed that Earth’s moon-sized inner core revolves independently of the mantle and crust, and that it is now backpedaling relative to those other layers.JOHAN63/ISTOCK/GETTY IMAGES PLUSA new study seems to support the contentious idea that the Earth's inner core's rotation has decelerated. Decades of earthquake data indicate that since around 2010, the...
Studies of marine shales and isotopic data from the Great Oxidation Event period reveal dynamic oxygen fluctuations in Earth’s early atmosphere and oceans, highlighting the prolonged and complex nature of this critical evolutionary stage.Recent findings indicate that Earth's "Great Oxidation Event" unfolded over a span of 200 million years.Fresh research underscores the intricate nature...
The Ocean Cleanup's Boyan Slat with an EcoRecord, which is made using a mix of plastic waste recovered from a river in Guatemala and recycled plastic bottles instead of vinyl, and will be the headline act for a limited-edition release of Coldplay's upcoming albumThe Ocean CleanupMarine plastic waste is a significant issue, but for...
Credit: DepositphotosA new study has confirmed that Earth's inner core rotation has indeed slowed, raising questions about the central dynamics of our planet and potential impacts on us.Researchers from the University of Southern California (USC) believe this alteration in the core’s rotation might slightly lengthen our days, though only by fractions of a second—so...
