Tundra - Carbon Sink to Source

April 28 , 2024 52 days 360 0
  • Arctic and alpine tundra ecosystems are known to be large reservoirs of organic carbon.
  • The warming planet may alter the characteristics of tundra environments and could transform them from carbon sinks to carbon sources.
  • Rising temperatures change the biogeochemistry of an area, affecting local soil by altering nitrogen levels and Ph.
  • A mean increase of 1.4 degrees Celsius in air temperature, 0.4°C in soil temperature and a 1.6 per cent drop in soil moisture led to a 30 per cent increase in respiration during the growing season.
  • The warming rate in the tundra biome could reach 0.73°C per decade, significantly outpacing the global average rate of 0.19°C per decade.
  • Furthermore, soil moisture decreased by 1.6 percent, influencing the tundra’s ability to function as a carbon sink.
