Robust increases in severe thunderstorm environments in response to greenhouse forcing

  • States that the response of thunderstorms to elevated greenhouse forcing has remained highly uncertain
  • Finds—using an ensemble of global climate model experiments—robust increases in the occurrence of severe thunderstorm environments over the eastern United States
  • Finds that simulated changes in the atmophseric environment also indicate an increase in the number of days supportive of convective hazards, suggesting a possible increase in the number of days that would support tornadic storms
  • States that these vulnerabilities imply increasing risk of thunderstorm-related damage if global warming continues
