    Antarctic ice shelves rapidly melting

    Antarctica’s ice shelves are shrinking at an accelerating rate, one of the longest satellite records of ice thickness reveals. Researchers report online March 26 in Science that several West Antarctic ice shelves are now on pace to disappear completely within 100 years.

    Floating ice shelves mark the...

    Rain slows whipping hurricane winds

    Heavy downpours put a damper on hurricanes, new research suggests.

    Running simple hurricane simulations, researchers have demonstrated that descending raindrops produce significant friction as they fall along the edges of a hurricane’s eye. This friction slows the powerful winds that drive the storm, lessening the hurricane’s intensity by as much as 30 percent, the researchers...

    Winter storms 24 times as deadly as estimated

    Jack Frost’s fury is deadlier than a major report implies, new research suggests.

    Yearly winter storm fatalities are tabulated in Storm Data, a report published by the National Oceanic and Atmospheric Administration. But Storm Data doesn’t include deaths indirectly caused by winter storms, such as precipitation-...

    Rise of East African Plateau dated by whale fossil

    A 17-million-year-old whale fossil is helping scientists pinpoint when the East African Plateau started to rise. Determining when the uplift happened has implications for understanding human evolution, scientists say.

    Shifts in the Earth’s mantle pushed the East African Plateau upward sometime between 17 million and 13.5 million years ago, researchers...

    Arctic warming bolsters summer heat waves

    Sweltering summertime heat waves are on the rise across the Northern Hemisphere because of atmospheric changes brought on by Arctic warming, new research shows.

    After examining 35 years of weather data, researchers spotted a decline in the strength of summer storms that carry cool, moist air across the northern continents. The sagging of these storms is the result of wind pattern changes...

    Insects may undermine trees’ ability to store carbon

    Trees are often promoted as an important tool for combating climate change. That’s because trees take in carbon dioxide from the air and lock it away in wood and soil for years. But trees may not be as great of carbon sinks as we thought, a...

    Volcanic lightning forges tiny glass balls from airborne ash

    Lightning bolts that flash and clash high above erupting volcanoes can forge flying ash into glass, new research finds. The mechanism could explain the origins of odd microscopic glass beads found embedded in ash deposits, the researchers report online February 27 in Geology.

    A volcanic eruption...

    Plant growth patterns changing on much of Earth’s surface

    Patterns in when and how much plants grow have changed markedly over the past 30 years, scientists report March 2 in Nature Climate Change.

    Researchers looked at satellite data of vegetation on the Earth’s surface from 1981 to 2012. They examined 21 markers of plant growth, including the dates when plants start sprouting and...

    Coastal Los Angeles losing fog to urban sprawl

    Morning fog along parts of coastal Southern California is disappearing due to nearby urbanization, new research suggests.

    Since 1948, fog frequency has plummeted 63 percent in the Los Angeles area, bioclimatologist A. Park Williams of Columbia University and colleagues report in a paper to be published in ...

    Scientists confirm amassing CO2 heats Earth’s surface

    For the first time, scientists have witnessed a direct connection between rising levels of atmospheric carbon dioxide and an increase in the amount of thermal radiation striking Earth’s surface. The work affirms a cornerstone of the theory that humans have contributed to worldwide warming in recent decades, the researchers report...
