  • Release of ancient methane due to changing climate kept in check by ocean waters
    on January 17, 2018 at 9:40 pm

    Ocean sediments are a massive storehouse for the potent greenhouse gas methane. But methane only acts as a greenhouse gas if and when it reaches the atmosphere. Environmental scientists recently set out to discover whether or not this ancient-sourced methane, which is released due to warming ocean waters, survives the journey from the seafloor and reaches the atmosphere. […]

  • New light on the mysterious origin of Bornean elephants
    on January 17, 2018 at 1:55 pm

    How did Borneo get its elephant? This could be just another of Rudyard Kipling's just so stories. The Bornean elephant is a subspecies of Asian Elephants that only exist in a small region of Borneo. Their presence on this southeastern Asian island has been a mystery. Scientists have discovered that elephants might have arrived on Borneo at a time of the last land bridge between the Sunda Islands in Southeast Asia. […]

  • Methane hydrate dissociation off Spitsbergen not caused by climate change
    on January 8, 2018 at 5:15 pm

    For years, methane emissions from the seabed have been observed in the Arctic Ocean off Spitsbergen. The assumption that the warming of seawater by climate change is responsible for the release of methane, has not been confirmed. Research shows that post-glacial uplift is the most likely cause of methane hydrate break-down. […]

  • Algae growth reduces reflectivity, enhances Greenland ice sheet melting
    on December 20, 2017 at 5:20 pm

    New research shows algae growing on the Greenland ice sheet, the Earth's second-largest ice sheet, significantly reduce the surface reflectivity of the ice sheet's bare ice area and contribute more to its melting than dust or black carbon. The new findings could influence scientists' understanding of ice sheet melting and projections of future sea level rise, according to the study's authors. […]

  • Life on the ice: For the first time scientists have directly observed living bacteria in polar ice...
    on December 20, 2017 at 5:20 pm

    For the first time scientists have directly observed living bacteria in polar ice and snow -- an environment once considered sterile. The new evidence has the potential to alter perceptions about which planets in the universe could sustain life and may mean that humans are having an even greater impact on levels of CO2 in Earth's atmosphere than accepted evidence from climate history studies of ice cores suggests. […]

  • East Antarctic Ice Sheet has history of instability
    on December 13, 2017 at 7:36 pm

    The East Antarctic Ice Sheet locks away enough water to raise sea level an estimated 53 meters (174 feet). It's also thought to be among the most stable, not gaining or losing mass even as ice sheets in West Antarctica and Greenland shrink. New research has found that the East Antarctic Ice Sheet may not be as stable as it seems. […]
