Heavy Metals and Other Toxins Found in Stranded Whales and Dolphins

Heavy Metals and Other Toxins Found in Stranded Whales and Dolphins

A new study has detected heavy metals and other toxins in whales and dolphins that became stranded in Florida and Georgia over a 15-year timeframe. Researchers analyzed tissue and fecal samples of 90 odontocetes (toothed whales), spanning nine different species, that had stranded in Florida and Georgia from 2007 to 2021. In total, the team […]

    Scientists Find Pollutants in Corals Linked to Burning Fossil Fuels

    Scientists Find Pollutants in Corals Linked to Burning Fossil Fuels

    While scientists have known that pollutants from human activities like agriculture, plastic production and coastal development threaten corals, a new study is the first to find pollutants tied to burning fossil fuels embedded in corals. Researchers from the Instituto de Acuicultura de Torre de la Sal collected samples from the coral species Cladocora caespitosa of […]

    Environmental Groups, Oil Industry File Separate Legal Challenges to Biden’s Offshore Drilling Plan

    Environmental Groups, Oil Industry File Separate Legal Challenges to Biden’s Offshore Drilling Plan

    Legal petitions have been filed in the United States Court of Appeals for the District of Columbia by environmental groups and oil and gas interests challenging the Biden administration’s plan to offer additional Gulf of Mexico drilling leases. The congressionally mandated five-year plan includes three sales — the least number being offered since 1980, reported […]

    Atlantic Ocean Current Weakening, Heading Toward Tipping Point, Study Finds

    Atlantic Ocean Current Weakening, Heading Toward Tipping Point, Study Finds

    Ocean currents are Earth’s climate regulators, distributing solar radiation and preventing regional temperatures from being more extreme. A new study has found that the Atlantic meridional overturning circulation (AMOC) — an important climate-regulating system of ocean currents — is headed toward a tipping point, though scientists aren’t sure how soon it will occur. “The Atlantic […]

    Controversial Study Says 1.5°C Warming Target Already Breached, ‘Underscores Urgent Need’ to Phase Out Fossil Fuels

    Controversial Study Says 1.5°C Warming Target Already Breached, ‘Underscores Urgent Need’ to Phase Out Fossil Fuels

    A new study using marine sponges collected off the coast of Puerto Rico has found that the planet has already warmed more than 1.5 degrees Celsius. Researchers analyzed ocean temperature records from sea sponges going back 300 years, a press release from The University of Western Australia (UWA) said. They concluded that global heating had […]

    Marine Heat Waves Can Impact Microorganisms Enough to Cause ‘Profound Changes’ to Ocean Food Chain

    Marine Heat Waves Can Impact Microorganisms Enough to Cause ‘Profound Changes’ to Ocean Food Chain

    Marine heat waves (MHWs) are prolonged periods of ocean warming that can significantly affect coral reefs, fish, kelp forests and other marine life. A new study led by Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) has found that MHWs are changing the communities of microorganisms that make up the foundation of the oceanic food […]
