    Oxygen in Black Sea has declined by more than a third since 1955

    The Black Sea’s toxic underside is approaching the surface, new research finds.

    Comparing measurements collected from 1955 through 2013, researchers discovered that the sea’s oxygen-rich top layer shrank by more than a third from 140 meters to 90 meters deep. That oxygenated layer supports a marine ecosystem and separates the atmosphere from the world’s largest reservoir of poisonous...

    Jumping conchs triumph at overheated athletics

    Conchs famed for one-footed jumping can beat many fishes at oxygenating athletic performance at high temperatures.

    Hunchbacked conchs (Gibberulus gibberulus gibbosus) can jump away if they sniff a predatory cone snail creeping near. But signs are mixed on how climate change will affect conch athletics. In the lab, conchs collected from the Great Barrier Reef...

    Some seabirds will be hit hard by sea level rise

    February 2011 was a bad month for seabirds living on the Midway, Kure and Laysan atolls. A winter storm swept across this portion of the North Pacific, with winds exceeding 115 kilometers per hour that whipped water across the low-lying islands. Then the Tohoku tsunami brought another bout of high...

    Alpine bee tongues shorten as climate warms

    As climate change has warmed the heights of the Rocky Mountains, the anatomy of some specialized bees has changed too, weakening their ancient partnerships with certain alpine flowers.

    Two species of long-tongued bumblebees now have tongues that are 24 percent shorter on average than those in specimens from the 1960s and 1970s, says ecologist Nicole Miller-Struttmann of State University...

    Hurricane reports ignore indirect deaths

    Hurricanes and other tropical storms are deadlier than just surging water and howling wind. Close to half of all storm fatalities are caused indirectly, new research shows.

    Storm reports typically include only deaths directly attributable to a storm’s physical forces, such as drowning in floodwater or being struck by airborne debris. Incidental deaths are excluded, such as those that...

    Warmer waters give Arctic mosquitoes a growth spurt

    Warmer water makes Arctic mosquitoes (Aedes nigripes) grow faster, Dartmouth College researchers report September 16 in the Proceedings of the Royal Society B. In the lab, mosquito larvae...

    Earth just had its first storm-free hurricane peak in 38 years

    September 12 marks the peak of the Atlantic Ocean hurricane season, but this year the day passed without any named storms. Odder still, the recently restless Pacific Ocean had a quiet day, too. In fact, across the entire Northern Hemisphere, not a single tropical storm swirled.

    This is the first September 12 without a major cyclone since 1977,...

    Burning remaining fossil fuels would eradicate Antarctic ice

    Exhausting all attainable fossil fuels would annihilate the Antarctic ice sheet and raise global sea levels by as much as 58 meters, more than the height of Niagara Falls, new research calculates.

    Enough fossil fuels remain to release around 10,000 billion tons of carbon into the atmosphere. The future of Antarctic ice ...

    Virtual twister reveals possible source of tornado longevity

    View the video

    A rotating updraft within this 20-kilometer-high thunderstorm sired a violent tornado. The twister, which looks quite small  compared with the rest of the towering storm, packed winds at over 320 kilometers per hour and left behind a long trail of devastation. Or it would have, had the storm been real.

    This realistic visualization of a supercell...

    Hurricane’s tiny earthquakes could help forecasters

    As Sandy raged, the ground trembled.

    Rumbles picked up by seismometers during Hurricane Sandy’s trip up the U.S. East Coast in 2012 originated from the storm’s eye, seismologists report in a paper to be published in the Journal of Geophysical Research: Solid Earth. Listening for these rumbles could help...
