Marine heatwaves, driven by rising ocean temperatures, are amplifying the economic impact of tropical cyclones, according to a new study. The research reveals that cyclones passing over these heatwaves rapidly intensify, becoming more destructive and nearly doubling the financial toll on affected regions.
The study, published by Carbon Brief, highlights how warmer ocean waters provide additional energy to cyclones, enabling them to grow stronger in shorter periods. This phenomenon, termed ‘supercharging,’ has been linked to increased wind speeds and heavier rainfall, both of which contribute to greater infrastructure damage and economic losses.
Analysts point to recent cyclones as evidence of this trend. ‘When marine heatwaves coincide with cyclones, the results are catastrophic,’ said one expert familiar with the research. ‘Coastal communities are facing unprecedented challenges.’
The findings underscore the broader implications of climate change, as warmer oceans are expected to fuel more frequent and intense cyclones in the coming decades. Policymakers and disaster response teams are urged to reconsider preparedness strategies in light of these risks.
