Short-Lived Climate Pollutants (SLCPs) typically stay in the atmosphere for a much shorter time than carbon dioxide. However, their warming effect on the atmosphere can be much greater. The main SLCPs behind current global warming are methane, tropospheric ozone, hydrofluorocarbons and black carbon. SLCPs play a major role in Arctic climate change. They cause direct warming from local emissions and from SLCPs that were transported to the Arctic by air. They also produce an overall increase in global temperatures, which indirectly contributes to warming in the Arctic.
