  • Greenland ice flow likely to speed up
    on August 16, 2017 at 6:18 pm

    Flow of the Greenland Ice Sheet is likely to speed up in the future, despite a recent slowdown, because its outlet glaciers slide over wet sediment, not hard rock, new research based on seismic surveys has confirmed. This sediment will become weaker and more slippery as global temperatures rise and meltwater supply becomes more variable. The findings challenge the view that the recent slowdowns in ice flow would continue in the long term. […]

  • Lunar dynamo's lifetime extended by at least 1 billion years
    on August 9, 2017 at 6:20 pm

    Astronomers report that a lunar rock collected by NASA's Apollo 15 mission exhibits signs that it formed 1 to 2.5 billion years ago in the presence of a relatively weak magnetic field of about 5 microtesla. That's around 10 times weaker than Earth's current magnetic field but still 1,000 times larger than fields in interplanetary space today. […]

  • Antarctic bacterium has one of the biggest proteins ever found
    on August 9, 2017 at 6:20 pm

    A bacterium living in the icy-cold waters of Antarctica manages to survive by gripping on to the ice surface. The protein used by the bacterium to do this -- a kind of extendable anchor -- has been detailed by a group of researchers. Quite special, because at 600 nanometers, it is one of the biggest proteins for which the structure has ever been identified. […]

  • Post-glacial history of Lake of the Woods
    on August 9, 2017 at 11:36 am

    The extent and depth of lakes in glaciated regions of North America are controlled by climate and the influence of differential isostatic rebound of the land's surface that began when Pleistocene ice melted from the continent. This relationship and the post-glacial history of Lake of the Woods -- one of the largest lake complexes in North America and the source of water for the city of Winnipeg -- is presented for the first time in a new study by five Canadian researchers. […]

  • Mountain glaciers recharge vital aquifers
    on July 21, 2017 at 1:54 pm

    Small mountain glaciers play a big role in recharging vital aquifers and in keeping rivers flowing during the winter, according to a new study. The study also suggests that the accelerated melting of mountain glaciers in recent decades may explain a phenomenon that has long puzzled scientists -- why Arctic and sub-Arctic rivers have increased their water flow during the winter even without a correlative increase in rain or snowfall. […]

  • Ancient Italian fossils reveal risk of parasitic infections due to climate change
    on July 20, 2017 at 7:53 pm

    In 2014, a team of researchers found that clams from the Holocene Epoch (that began 11,700 years ago) contained clues about how sea level rise due to climate change could foreshadow a rise in parasitic trematodes. Now, an international team has found that rising seas could be detrimental to human health on a much shorter time scale. […]

  • Removing CO2 from the air required to safeguard children's future
    on July 18, 2017 at 3:37 pm

    Reducing greenhouse-gas emissions is not enough to limit global warming to a level that wouldn't risk young people's future, according to a new study by scientists who say we need negative emissions. Measures such as reforestation could accomplish much of the needed CO2 removal from the atmosphere, but continued high fossil fuel emissions would demand expensive technological solutions to extract CO2 and prevent dangerous warming. […]

  • Stronger winds heat up West Antarctic ice melt
    on July 17, 2017 at 3:54 pm

    Stronger winds 6000kms away on the East Antarctic, have generated waves that circle the continent at almost 700kmh. When these waves meet the steep underwater topography of the West Antarctic Peninsula they push warm water under the ice shelves. This helps explain the increased ice melt in this region that can lead trillion tonne ice shelves, like Larsen C, to break away from the continent. […]
