Overarching goal for this project is to entangle how anthropogenic emissions of Short Lived Climate Pollutants (SLCP), aerosols (including sulfates, black carbon and organic carbon), methane and other ozone forming pollutants from different regions of the world (Europé, North America, East and South Asia) affect the global climate and specifically the Arctic. The purpose is two fold; firstly to further investigate the key processes behind the Arctic amplification, that is not well understood and secondly to quantify how much anthropogenic SLCP emission reductions in different regions of the world affect the climate in different parts of the world and specifically the Arctic, through Regional Temperature Potentials. The NorESM model will be used to quantitatively evaluate how past emissions of the different regions of the Northern Hemisphere have affected the climate, especially in the Arctic. Air Quality regulations have forced strongly decreased emissions of sulfate, black carbon, ozone precursors and other air pollutants in Europe and North America while in other parts the emissions have increased especially in strongly developing economies. It is of importance for the future work within CLRTAP and other organizations focused on air quality regulation to protect environment and humans, but especially for organizations as AMAP and CCAC concerned with regulation of SLCPs to reduce climate change in especially endangered areas as the Arctic.
