This study investigates the global increase in tropical cyclone rapid intensification (RI) events. By comparing observed trends with simulations from a high-resolution global climate model, the authors find a significant increase in intensification rates, with a positive contribution from anthropogenic forcing. Thermodynamic environments around tropical cyclones have become more favorable for intensification, and climate models indicate that anthropogenic warming has substantially increased the probability of these changes. The study highlights the need for improved coastal resilience to prepare for more frequent and intense hurricanes.
