Arctic coastal degradation releases more locked up greenhouse gases: Study

  • Coasts containing frozen soil called permafrost make up about one third of the Earth’s total coastline, and as these melt in the Arctic under global warming, large quantities of carbon dioxide is being released into the atmosphere.
  • The researchers, including those from GFZ Helmholtz Centre Potsdam in Germany, simulated the effects of permafrost erosion in a lab experiment to find out how much carbon is released into the atmosphere along eroding Arctic coasts.
  • The research team took periodic measurements of greenhouse gases this mixture emitted over the course of four months — the average length of open-water season in the Arctic.
