Researchers recommend ways to fight lake trout invasion in Glacier National Park from PhysOrg.com
Natural barriers like waterfalls play an important role in preventing lake trout from spreading through Glacier National Park, so maintaining those barriers should be a priority, Montana State University researchers said after conducting a four-year study in the park.
Ozone hole recovery may reshape southern hemisphere climate change from PhysOrg.com
A full recovery of the stratospheric ozone hole could modify climate change in the Southern Hemisphere and even amplify Antarctic warming, according to scientists from the University of Colorado at Boulder, the National Oceanic and Atmospheric Administration and NASA.
Stratospheric injections to counter global warming could damage ozone layer from PhysOrg.com
A much-discussed idea to offset global warming by injecting sulfate particles into the stratosphere would have a drastic impact on Earth's protective ozone layer, new research concludes. The study, led by Simone Tilmes of the National Center for Atmospheric Research (NCAR), warns that such an approach might delay the recovery of the Antarctic ozone hole by decades and cause significant ozone loss over the Arctic.
