    Rainwater can help trigger earthquakes

    Where it rains, it rumbles. Rainwater and snowmelt help fuel intense earthquakes along a New Zealand tectonic fault, new research suggests.

    Tracing the source of water flowing through New Zealand’s Alpine Fault shows that more than 99 percent of it originated from precipitation, researchers report April 19...

    Fizzled 2014 El Niño fired up ongoing monster El Niño

    The historic El Niño event currently shaking up Earth’s weather rose like a phoenix from the hot remains of a failed 2014 El Niño, new research suggests.

    In 2014, the scientific community buzzed about the possibility of a supersized El Niño as warm Pacific Ocean water sloshed eastward. That July, however, large winds pushed westward and halted the budding El Niño before it fully formed...

    Bacterium still a major source of crop pesticide

    Bacterium effective when dusted on plants — The successful agent for destroying pesty insects, the microscopic bacterium, Bacillus thuringiensis, is most effective when it is dusted onto tobacco or other plants…. The bacteria are now...

    How alien can a planet be and still support life?

    Just how fantastical a planet can be and still support recognizable life isn’t just a question for science fiction. Astronomers are searching the stars for otherworldly inhabitants, and they need a road map. Which planets are most likely to harbor life? That’s where geoscientists’ imaginations come in. Applying their knowledge of how our world works and what allows life to flourish, they are...

    Scientists find a crab party deep in the ocean

    A year ago, researchers in two small submarines were exploring a seamount — an underwater, flat-topped mountain — off the Pacific coast of Panama when they noticed a dense cloud of sediment extending 4 to 10 meters above the seafloor. One of the submarines approached closer, and the scientists could soon see what was kicking up the cloud: thousands of small, red crabs that were swarming...

    Wildfire shifts could dump more ice-melting soot in Arctic

    Raging wildfires could burn away efforts to reduce Arctic-damaging soot emissions. Soot produced by burning fossil fuels and plants, also called black carbon, can cause respiratory diseases and greenhouse warming, and can accelerate the melting of ice.

    Rising temperatures and changing weather patterns will shift where and how fiercely wildfires burn and spew soot, new simulations show....

    EPA boosts estimate of U.S. methane emissions

    The U.S. Environmental Protection Agency, criticized for understating how much methane the United States spews into the atmosphere, has boosted its estimate of total U.S. methane emissions by 13 percent. That’s an increase of more than 3.4 million metric tons of the greenhouse gas and has the same long-term global warming impact as a year’s worth of emissions from about 20 million cars.

    Heat may outpace corals’ ability to cope

    Corals are in hot water — and may soon lose their ability to handle the heat.

    In Australia’s Great Barrier Reef, most past bouts of warming allowed many corals to adjust their physiology and avoid serious damage. But as waters warm even more, corals could run out of wiggle room, researchers report in the April 15...

    EPA underestimates methane emissions

    The U.S. Environmental Protection Agency has a methane problem — and that could misinform the country’s carbon-cutting plans. Recent studies suggest that the agency’s reports fail to capture the full scope of U.S. methane emissions, including “super emitters” that contribute a disproportionate share of methane release. Those EPA reports influence the country’s actions to combat climate change...

    Pollen becoming bee junk food as CO2 rises

    Bees may need their own supplemental protein shakes as increasing carbon dioxide in the atmosphere saps the nutritional quality of pollen.

    Pollen collected from plants gives bees their only natural source of protein (nectar is a sugar-shot for energy). Yet protein content in pollen of a widespread goldenrod species (Solidago canadensis)...
