    Pink salmon threatened by freshwater acidification

    As carbon dioxide levels in the atmosphere rise, the world’s oceans are absorbing some of the gas and slowly becoming more acidic. That acidification impedes the chemical reaction that many marine species use to make calcium carbonate shells and skeletons. Fish were once thought to be immune to the drop in pH, but...

    Fast-spreading crack threatens giant Antarctic ice shelf

    Scientists have spotted the mortal wound that could prompt the collapse of Antarctica’s fourth-largest ice shelf.

    Satellite images reveal that a crack in Larsen C rapidly extended tens of kilometers across the ice shelf in 2014. If the crack reaches the ice shelf’s edge, it could snap off a Delaware-sized area of ice, researchers...

    Many of Earth’s groundwater basins run deficits

    Climate and human consumption are parching Earth’s groundwater basins at an alarming rate, a new study finds. Of Earth’s 37 biggest groundwater basins, 21 now lose more water annually than they take in, researchers report in a paper to be published in Water Resources Research.

    That’s troubling,...

    Greenhouse effect from fossil fuels felt almost immediately

    The planet quickly feels the burn from the lasting effects of fossil fuel combustion, new research shows.

    When a fossil fuel burns, it radiates heat and releases carbon dioxide. Once in the atmosphere, some of that CO2 can linger for thousands of years and trap heat that would otherwise leak into space. Over the lifetime of the released CO2, the trapped heat exceeds...

    Real estate is tight as marine species move to cooler waters

    Many marine species trekking to cooler locales amid global warming will have to settle for smaller digs, two studies suggest June 4 in Science.

    In one study, researchers investigated the migration of 104 species of staghorn coral (in the genera Acropora and Isopora), which are dependent...

    Global warming ‘hiatus’ just an artifact, study finds

    One of the biggest mysteries of modern climate science may never have really existed, updated climate analyses suggest.

    Following decades of warming and a hot 1998, Earth’s average surface temperature seemingly plateaued. This warming hiatus, as it came to be known, had climate researchers scrambling for an explanation. Now measurements and analysis by the National Oceanic and...

    Titanic typhoons are in the forecast

    Warming waters will boost the destructiveness of future typhoons, new research predicts.

    Studying 60 years of typhoon activity in the western Pacific Ocean, researchers spotted a clear trend: A typhoon’s ultimate intensity largely depends on the temperature of deep seawater churned upward as the storm passes overhead. Projecting their finding into the future, the researchers...

    Everest could lose most of its ice by the end of the century

    Glaciers around the tallest mountain in the world may reach a historic new low relatively soon.

    Combining projections of future climate with simulations of how glaciers melt and grow, researchers estimate online May 27 in The Cryosphere that the Everest region of the Himalayas...

    Everest could lose most of its ice by 2100

    Glaciers around the tallest mountain in the world may reach a historic new low relatively soon.

    Combining projections of future climate with simulations of how glaciers melt and grow, researchers estimate May 27 in The Cryosphere that the Everest region of the Himalayas could lose 73 to 96...

    Next icy era may be on hold

    The next big chill may be overdue. If humans hadn’t boosted levels of atmospheric carbon dioxide, Earth’s next frosty bout of glacial growth probably would have already started, new research suggests.

    For the last 11,700 years, Earth has been on a break between periods of ice expansion called glaciations. A similar interglacial period occurred around 790,000 years ago. A new climate...
