Statements
Changes in short-lived climate forcers (SLCF) resulting from the five considered scenarios lead to an additional net global warming in the near and long term. (English)

Simultaneous stringent climate change mitigation and air pollution control policies limit this additional warming and lead to strong benefits for air quality. (English)

In high and very high GHG emissions scenarios (SSP3-7.0 and SSP5-8.5), combined changes in SLCF emissions, such as CH4, aerosol and ozone precursors, lead to a net global warming by 2100 of likely 0.4°C–0.9°C relative to 2019. This is due to projected increases in atmospheric concentration of CH4, tropospheric ozone, hydrofluorocarbons and, when strong air pollution control is considered, reductions of cooling aerosols. In low and very low GHG emissions scenarios (SSP1- 1.9 and SSP1-2.6), air pollution control policies, reductions in CH4 and other ozone precursors lead to a net cooling, whereas reductions in anthropogenic cooling aerosols lead to a net warming.

Altogether, this causes a likely net warming of 0.0°C–0.3°C due to SLCF changes in 2100 relative to 2019 and strong reductions in global surface ozone and particulate matter. (English)
