  • Record for perovskite/CIGS tandem solar module
    Thin-film technologies can dramatically reduce the cost of next-generation solar modules. Whereas their production cost is low, it is in particular the combination of complementary absorber mat...Thin-film technologies can dramatically reduce the cost of next-generation solar modules.

  • Life in ancient oceans enabled by erosion from land
    As scientists continue finding evidence for life in the ocean more than 3 billion years ago, those ancient fossils pose a paradox. Organisms, including the single-celled bacteria living in the ...As scientists continue finding evidence for life in the ocean more than 3 billion years ago, those ancient fossils pose a paradox.

  • Natural gas versus diesel: Examining the climate impacts of natural gas trucks
    Burning natural gas emits less carbon dioxide (CO?) into the atmosphere than other fossil fuels, but the process of getting natural gas out of the ground and delivering it through pipelines re...Burning natural gas emits less carbon dioxide (CO?) into the atmosphere than other fossil fuels, but the process of getting natural gas out of the ground and delivering it through pipelines re...
  • How wetlands and agriculture, not fossil fuels, could be causing a global rise in methane
    Atmospheric methane is a major greenhouse gas that traps heat in our atmosphere, contributing to global warming. Its levels have been growing strongly since 2007, and in 2014 the growth rate of...Atmospheric methane is a major greenhouse gas that traps heat in our atmosphere, contributing to global warming.

  • 92% of the world’s population exposed to unsafe levels of air pollution
    "The new WHO model shows countries where the air pollution danger spots are, and provides a baseline for monitoring progress in combatting it," says Dr Flavia Bustreo, Assistant Director Genera..."The new WHO model shows countries where the air pollution danger spots are, and provides a baseline for monitoring progress in combatting it," says Dr Flavia Bustreo, Assistant Director Genera...
  • Flooding and drought in opposing mountain ranges
    To calculate and compare each region's water balance, the researchers created a new and very extensive model of the upper Langtang valley in Nepal and the Juncal region of the central Andes in ...
  • Warm ocean current reaches surprisingly far south in the Antarctic Weddell Sea
    Warm ocean water of open ocean origin is continuously flowing into the cavities below the ice shelves in the Amundsen and Bellinghausen Sea, west of the Antarctic peninsula, thus melting them f...
  • Trees on farms: The missing link in carbon accounting
    According to the International Panel on Climate Change (IPCC), agriculture and land-use change account for about 24% of the world's greenhouse gas emissions. Climate change will also have stron...
  • Managing uncertainty: How soil carbon feedbacks could affect climate change
    Yet in its most recent report, in 2013, the Intergovernmental Panel on Climate Change (IPCC) used models that paid less attention to soil carbon potentially entering the atmosphere than had ear...
  • Impact of extreme weather events on striped bass
    Researchers from the University of Maryland Center for Environmental Science wanted to know the impact of severe storms on fish populations that have to make sudden and unexpected trips downstr...
