Abstract

Short-lived Climate Forcers (SLCFs) are reactive gases or aerosols that influence the Earth’s energy balance via their direct effects on radiation or through their effects on the abundances of radiatively active compounds through chemistry. Their climate effects occur predominantly in the first two decades after their emission or formation. Additionally, many SLC Fs are also air pollutants with harmful effects on human health and ecosystems. Chapter 6 of the sixth Assessment Report (AR6) of the Working Group I of the Intergovernmental Panel on Climate Change (IPCC) assessed the changes, in the past and in a selection of possible futures, of SLCF emissions and abundances primarily on global and continental scale and their effects on the Earth’s energy balance through radiative forcing and feedback in the climate system. In this talk, I will present key findings on the role of SLC Fs in the climate system as assessed in the AR6 .
