  • 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. […]

  • How future volcanic eruptions will impact Earth's ozone layer
    on August 16, 2017 at 4:23 pm

    The next major volcanic eruption could kick-start chemical reactions that would seriously damage the planet's already besieged ozone layer. The extent of damage to the ozone layer that results from a large, explosive eruption depends on complex atmospheric chemistry, including the levels of human-made emissions in the atmosphere. Using sophisticated chemical modeling, researchers explored what would happen to the ozone layer in response to large-scale volcanic eruptions over the remainder of this century and in several different greenhouse gas emission scenarios.

  • Climate change: Silver fir beats Norway spruce and European beech
    on August 10, 2017 at 12:21 pm

    Climate change is making Swiss forests warmer and drier. The trees would have to adapt genetically to the rapidly changing climate to continue flourishing at their current growth location. Yet, they are unlikely to do so in such a short period of time – a single tree generation already takes 100 years or longer. Therefore, the question on how well adapted the trees already are today to the future climate will be crucial for the forests' future. […]

  • New technique offers clues to measure the deoxygenation of the ocean
    on August 9, 2017 at 6:20 pm

    The living, breathing ocean may be slowly starting to suffocate. More than two percent of the ocean's oxygen content has been depleted during the last half century, according to reports, and marine 'dead zones' continue to expand throughout the global ocean. This deoxygenation, triggered mainly by more fertilizers and wastewater flowing into the ocean, pose a serious threat to marine life and ecosystems. […]

  • 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. […]

[…]

  • Biochar shows benefits as manure lagoon cover
    on August 9, 2017 at 6:02 pm

    Manure is a reality in raising farm animals. Manure can be a useful fertilizer, returning valued nitrogen, phosphorus, and potassium to the soil for plant growth. But manure has problems. Odor offensiveness, gas emissions, nutrient runoff, and possible water pollution are just a few. New methods may reduce these negatives while potentially adding some positives: biochar covers. […]

  • Cause of Atlantic coastline's sea level rise hot spots now revealed
    on August 9, 2017 at 6:01 pm

    Seas rose in the southeastern US between 2011 and 2015 by more than six times the global average sea level rise that is already happening due to human-induced global warming, new research shows. The combined effects of El Niño (ENSO) and the North Atlantic Oscillation (NAO), both of which are naturally occurring climate processes, drove this recent sea level rise hot spot, according to the study. […]
