Trout living in rivers polluted by metal from old mines across the British Isles are genetically “isolated” from other trout, new research shows.

Down on the south end of California’s San Joaquin Valley, oil rigs have plumbed the earth like flocks of blackened drinking birds for more than a century.

If we want cleaner air, fewer forest fires, and less severe climate change, a new UC Riverside study shows we must reduce aerosol pollution and greenhouse gases like carbon dioxide at the same time.

Researchers have been working to track and study floating sargassum, a prolific seaweed swamping Caribbean and West African shorelines, and causing environmental and economic harm.

They call it “The Blob.” A vast expanse of ocean stretching from Alaska to California periodically warms by up to 4 degrees Celsius (7 degrees F), decimating fish stocks, starving seabirds, creating blooms of toxic algae, preventing salmon returns to rivers, displacing sea lions, and forcing whales into shipping lanes to find food.

Researchers at Tampere University have discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids. 

Boilers are a major source of greenhouse gas emissions.

Major pollutants affecting the Lake District’s iconic waters are continuing to decline across the region, but a combination of factors continue to impact the health of lake ecosystems, say scientists.

Research suggests that plastic pollution must be reduced by at least 5% every year to make progress towards UN targets by the end of the century.

Scientists looking to convert carbon dioxide into clean fuels and useful chemicals often make hydrogen gas and carbonates as unwanted byproducts.
