Projected rapid response of stratospheric temperature to stringent climate mitigation

G. Romanzini-bezerra and A. C. Maycock

Discover how rapid emission cuts can significantly alter stratospheric temperature trends within just five years! Research by Grasiele Romanzini-Bezerra and Amanda C. Maycock reveals that these changes could be crucial early indicators of climate mitigation effectiveness.

Abstract
This paper investigates the projected near-term global temperature trends at the surface and in the stratosphere using large ensemble climate models under three emission scenarios. It finds that under rapid emission cuts (SSP1-1.9), stratospheric cooling trends become detectably weaker within 5 years compared to a scenario representing current commitments (SSP2-4.5). Therefore, stratospheric temperature trends could serve as an early indicator of climate mitigation effectiveness.
