• Bahamian Songbirds Disappeared During Last Glacial-Interglacial Transition

    Two species of songbirds that once made a home in the Bahamas likely became extinct on the islands because of rising sea levels and a warmer, wetter climate, according to a new study by researchers at the University of California, Riverside and the University of Florida, Gainesville. The study, which was published today in the Proceedings of the National Academy of Sciences, presents a historical view of how climate change and the resulting habitat loss can affect Earth’s biodiversity.

  • Climate Change Could Cause Fish to Shrink in Size

    In the coming decades, warming ocean temperatures could stunt the growth of fish by as much as 30 percent, according to a new study in the journal Global Change Biology.

    The main driver behind this decline in size is that warmer water contains less oxygen. As Nexus Media explains, fish are cold-blooded animals and therefore cannot regulate their own body temperatures. So as oceans heat up, a fish’s metabolism accelerates to cope with the rising temperatures and they need more oxygen to sustain their body functions. But fish gills do not grow at the same pace as the rest of their body, resulting in a decline of oxygen supply and in growth.

  • Algae Fortifies Coral Reefs in Past and Present

    The Great Barrier Reef, and most other large reefs around the world, owe their bulk in large part to a type of red algae that grows on corals and strengthens them. New research led by Anna Weiss, a Ph.D. candidate at The University of Texas at Austin Jackson School of Geosciences, has found that ancient coral reefs were also bolstered by their bond with red algae, a finding that could help scientists better understand how reefs will respond to climate change.

    “Coral reefs as we know them today are a product of that long term coral-coralline algae relationship,” Weiss said. “So if we want to preserve our coral reefs, we need to pay attention to the health of coralline algae as well.”

  • Caspian Sea evaporating as temperatures rise

    Earth’s largest inland body of water has been slowly evaporating for the past two decades due to rising temperatures associated with climate change, a new study finds.

  • Potential Tropical Cyclone 10 Soaks Mid-Atlantic

    NOAA's GOES East satellite provided an image of Potential Tropical Cyclone 10 as it continued moving north along the U.S. East Coast.

    The system is still not a tropical cyclone and the chances for the system to become a tropical cyclone appear to be decreasing. Regardless, National Hurricane Center noted that tropical-storm-force winds and heavy rains are expected over portions of North Carolina later today, Aug. 29.

    A Tropical Storm Warning was in effect from north of Surf City to Duck, North Carolina and for the Albemarle Sound and Pamlico Sound.

  • Strength of global stratospheric circulation measured for first time

    When commercial airplanes break through the clouds to reach cruising altitude, they have typically arrived in the stratosphere, the second layer of Earth’s atmosphere. The air up there is dry and clear, and much calmer than the turbulent atmosphere we experience on the ground.

    And yet, for all its seeming tranquility, the stratosphere can be a powerful conveyor belt, pulling air up from the Earth’s equatorial region and pushing it back down toward the poles in a continuously circulating pattern. The strength of this circulation can significantly impact the amount of water vapor, chemicals, and ozone transported around the planet.

  • Dispersants Improved Air Quality for Responders at Deepwater Horizon

    A study published Aug. 28, 2017, in the Proceedings of the National Academy of Sciencesadds a new dimension to the controversial decision to inject large amounts of chemical dispersants immediately above the crippled oil well at the seafloor during the Deepwater Horizon disaster in 2010. The dispersants likely reduced the amount of harmful gases in the air at the sea surface—diminishing health risks for emergency responders and allowing them to keep working to stop the uncontrolled spill and clean up the spilled oil sooner.

  • NASA sees Tropical Storm Harvey moving back into the Gulf

    On Monday, Aug. 28 at 7 a.m. CDT the National Hurricane Center said the center of Harvey is emerging into the Gulf of Mexico. A NASA animation of imagery from NOAA's GOES East satellite shows Harvey as it lingered over southeastern Texas over the weekend of Aug. 26 and 27 and moving back toward the Gulf of Mexico on Aug. 28.

    The National Hurricane Center noted "life-threatening flooding continues over southeastern Texas." NHC stressed that people should never attempt to travel into flooded roadways.
