Seabird activity is contributing significantly to methane and nitrous oxide emissions in the Arctic tundra, a new study shows. Methane emissions, which play an important role in the global carbon cycle, and nitrous oxide fluxes, a key element in the nutrient cycle, are predicted to increase in the Arctic and contribute to Arctic warming in the near future.
