Title

Radiative forcing from the 2014-2022 volcanic and wildfire injections

Abstract

Volcanic and wildfire events between 2014 and 2022 injected SIM;3.2 Tg of sulfur dioxide and 0.8 Tg of smoke aerosols into the stratosphere. With injections at higher altitudes and lower latitudes, the simulated stratospheric lifetime of the 2014-2022 injections is about 50% longer than the volcanic 2005-2013 injections. The simulated global mean effective radiative forcing (ERF) of 2014-2022 is -0.18 W m(-2), SIM;40% of the ERF of the period of 1991-1999 with a large-magnitude volcanic eruption (Pinatubo). Our climate model suggests that the stratospheric smoke aerosols generate SIM;60% more negative ERF than volcanic sulfate per unit aerosol optical depth. Studies that fail to account for the different radiative properties of wildfire smoke relative to volcanic sulfate will likely underestimate the negative stratospheric forcings. Our analysis suggests that stratospheric injections offset 20% of the increase in global mean surface temperature between 2014-2022 and 1999-2002.
