Mitigating Arctic warming

Norwayfjord


  1. Context: The warming in Arctic region can be reduced by 0.2 degrees C by 2050 by cutting down emissions of short-lived climate forcers
  2. Includes: Black carbon, sulphur dioxide, nitrogen oxides (NOx), volatile organic compounds, organic carbon and tropospheric ozone
  3. Focus of Study: Effect of emission of each of these agents on Arctic temperature and contribution to warming or cooling
  4. Relevance: Short-lived climate forcers are particulate matter of various kinds emitted into atmosphere by natural and anthropogenic sources
  5. This emissions stay in atmosphere for at most a period of 1 month but cutting down their emissions can bring in results quickly.
  6. Important Findings: Largest absolute contributor (including both warming and cooling emissions) was the Asian region with domestic activities emitting large amounts of black carbon
  7. Highest per unit warming was from flaring emissions from Russia followed by forest fires and flaring from Nordic countries
