    Thinning ice leads to winter warming in the Arctic

    Even when the Arctic goes dark and cold, thinning ice could keep the North Pole from cooling off.

    The loss of insulating ice between the ocean and atmosphere increases the amount of heat-trapping water vapor and clouds in the Arctic air. That extra moisture keeps air temperatures relatively warm during fall and winter and...

    Getting creative to cut methane from cows

    View the video

    In a pasture outside Edmonton, Canada, you’ll find a few dozen cows doing what cows do: mostly eating. The average animal spends eight-plus hours a day filling its belly, or as is the case with cows, bellies. Along with that enormous appetite, cows are born with the ability to digest almost any plant they can chew, thanks to a multichambered stomach...

    Geoengineering is world’s last hope, new book argues

    The Planet Remade

    Princeton Univ., $29.95

    The plans sound like something out of the handbook of a James Bond villain: generate artificial volcanic eruptions,...

    Kangaroo farts may not be so eco-friendly after all

    Kangaroos do blow farts spiked with methane.

    More methane is escaping the behinds of kangaroos than previously thought, an international group of researchers reports online November 4 in the Journal of Experimental Biology. It’s still less than many other grazing animals, though, the researchers say. They think that...

    Eocene temperature spike caused by half as much CO2 as once thought

    The hottest time since dinosaurs roamed the planet was caused by nearly half as much carbon dioxide in the air as previously thought, crystals from Earth’s past suggest.

    During the Eocene around 50 million years ago, climbing CO2 levels heated the planet by more than 5 degrees Celsius. By examining crystals grown in this “hothouse” climate, researchers discovered that Eocene...

    How to melt an ice cave

    If you want to keep an ice cave cold, don’t shut the door.

    That’s the lesson learned from studying China’s largest year-round ice cave, which thankfully has no doors to close and is just fine. Cold winter breezes act as natural air conditioning and keep this frozen grotto perpetually chilly, researchers report October 22 inThe Cryosphere. And summer heat barely penetrates its...

    Rising temperatures complicate efforts to manage cod fishery

    Warming waters in the Gulf of Maine have reduced Atlantic cod populations in that region and distorted estimates of how many fish were available to catch, a new study finds.

    Cod stocks have decreased even though fishing quotas should have maintained a sustainable cod fishery. But those quotas relied on historical data without considering higher water temperatures, leading to incorrect...

    Parched parts of Earth expanding

    Arid, hardscrabble landscapes could cover more than half of Earth’s land surface by 2100, a new study finds.

    The expansion of drylands — fragile regions where vegetation is sparse and soil is fairly infertile — will predominantly occur in developing countries, according to new climate change simulations published October...

    Wi-Fi threatens weather forecasts

    Wireless technology dangerously clutters the airwaves that meteorologists rely on to monitor thunderstorms, hurricanes and tornadoes, blacking out large swaths of weather radar maps.

    Wi-Fi, remote surveillance cameras and other wireless tech emit radio waves that can disrupt those from weather radars. This interference, which...

    Hurricane Patricia’s howling winds smash records

    Hurricane Patricia is now the strongest hurricane ever recorded in the Western Hemisphere, with maximum sustained wind speeds reaching 325 kilometers per hour (200 miles per hour), the National Hurricane Center reports.

    The monster storm bests the record peak sustained winds of 315 kilometers per hour (195...
