    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 Letters: Solid Earth. Listening for these rumbles...

    Katrina’s legacy: Refining hurricane forecasting

    Ten years ago, the sea and sky rallied to unleash one of the worst natural disasters in U.S. history. During the 2005 Atlantic hurricane season, the most active season on record, 27 named storms —from Arlene to Zeta — swirled into existence. By far the most destructive was Hurricane Katrina.

    Katrina killed nearly 2,000 people and caused an unprecedented $108 billion in damage from the...

    Carbon cuts could save U.S. farmers billions of dollars

    U.S. agriculture could reap big benefits from curbed carbon emissions. Such cuts would reduce the frequency and severity of future crop-parching droughts, saving American farmers billions of dollars annually by 2100, researchers calculate in the July issue of Weather, Climate and Society.

    Calculating how changes in...

    Iceless Arctic summers now expected by 2050s

    Santa Claus could be treading water sooner than thought. An improved forecast of Arctic sea ice coverage predicts that the region will have its first ice-free summer almost a decade earlier than previously projected.

    Climate scientists fine-tuned simulations of future climate by adding ice‒ocean interactions and measurements that were more detailed than previously used. The tweaks reduce...

    Desert dig uncovers caches of missing CO2

    The wet undersides of deserts may stash as much as a trillion metric tons of climate-altering carbon, more than stored in all land-based plants, new research suggests.

    Human activities such as burning fossil fuels spew carbon dioxide into the atmosphere. Scientists, however, can’t account for where as much as 30 percent of this CO2 ends up.

    “We’ve found a carbon sink in...

    Sudden heat spikes did in Ice Age’s mammoth mammals

    Rapid climate change put mega-sized Ice Age mammals on the ropes before ancient humans delivered the final blow, new research indicates.

    During Earth’s last glacial period, around 12,000 to 110,000 years ago, woolly mammoths, sedan-sized armadillos and other massive mammals walked the land. Over time, these megafauna mostly died out. The instigator of these extinctions has become a topic...

    Sea level rise threatens sea turtles

    Sea levels are rising around the world, and they will continue to do so as glaciers and ice sheets melt and the world’s oceans undergo thermal expansion. How much rise will occur is still unknown — one study published online this week contends it could be as much as three...

    Carbon dating may soon lead to mismatches

    The accuracy of carbon dating may soon be a thing of the past.

    Carbon emissions from burning fossil fuels threaten the method’s ability to definitively pinpoint the age of organic materials, new research suggests. The extra carbon flooding the atmosphere dilutes the relative number of radioactive carbon atoms that are vital to the dating method. By 2050, the age of fresh organic matter...

    Blooming phytoplankton seed clouds in the Southern Ocean

    A plethora of phytoplankton kick up clouds in the Southern Ocean, researchers report July 17 in Science Advances.

    The tiny ocean critters release organic matter and sulfates, which get whipped into the air and seed cloud formation. Those clouds reflect sunlight, helping to cool the planet. Using satellite data and...
