N2 - We investigate the transient response of severethunderstorm forcing to the time-varying greenhouse gas concentrations associated with the AlB emissions scenario. Using a five-member ensemble of global climate model experiments, we find a positive trend in such forcing within the United States, over the period 1950-2099. The rate of increase varies by geographic region, depending on (i) low-level water vapor availability and transport, and (ii) the frequency of synoptic-scale cyclones during the warm season. Our results indicate that deceleration of the greenhouse gas emissions trajectory would likely result in slower increases in severe thunderstorm forcing.
