How is the Arctic air and climate affected by soot particles?
The Arctic is experiencing dramatic, transformative effects of climate change. An important contributing factor to climate change is soot particles. In the EU project Arctic Black Carbon Impacting on Climate and Air Pollution (ABC-iCAP), work is under way to learn more about and limit the climate impacts of soot.
Black carbon, i.e. soot, is produced by incomplete combustion of fossil fuels and biomass. As dark particles they absorb heat from the sun, and when they land on snow and ice, the melt rate can accelerate. Thus, black carbon tributes significantly to the warming of the Arctic, and is an air pollutant that affects people's health very negatively.
ABC-iCAP is a continuation of the EU project Action on Black Carbon, which started in 2017. Like its predecessor, ABC-iCAP helps support the international collaboration aimed at reducing the emission of soot particles by developing technical decision support and scenario analyses. the project is managed by the Norwegian Arctic Monitoring and Assessment Program (AMAP).
