Polar Amplification

  • Due to the concentration of greenhouse gases in the polar region due to climate change, there is more thermal change at the poles than in the rest of the world, this phenomenon is called 'polar amplification'.
  • Ice-albedo reaction, lapse rate reaction, water vapour reaction and ocean heat transfer are the primary causes of polar amplification.
  • These changes are more pronounced at northern latitudes than at southern latitudes, a process known as 'Arctic amplification'.
  • Melting sea ice would make the Arctic Ocean more able to absorb solar radiation, which would further increase Arctic amplification.
