Human-caused climate change has significantly contributed to the destructive winds and rainfall of Hurricane Melissa, a study released Thursday reveals. The hurricane, one of the strongest to hit the Atlantic, has left a trail of devastation across Jamaica, Haiti, the Dominican Republic, and Cuba, resulting in numerous fatalities.
According to an analysis by World Weather Attribution, climate change intensified Melissa's maximum wind speeds by 7% and increased its rainfall intensity by 16%. The environmental conditions that fueled the storm were found to be six times more likely to occur due to climate change than in a pre-industrial context.
Melissa's path was marked by record ocean temperatures, approximately 1.4°C (2.5°F) higher than pre-industrial levels, which provided the necessary energy to fuel the storm's intensity. Climate scientist Theodore Keeping highlighted that warmer ocean temperatures enhance wind speeds, stating, “the warmer the ocean temperatures, the greater the wind speed a hurricane can have.”
This year, Melissa is the fourth Atlantic storm to experience rapid intensification, illustrating a worrying trend linked to global warming. Keeping noted that without human influence, the wind speeds would have been considerably lower, resulting in less destructive potential.
Research underscores the connection between rapid hurricane intensification and climate change. Increased atmospheric water vapor and warmer oceans provide hurricanes with more fuel to unleash catastrophic rainfall and intensify more swiftly. Academy of Atmospheric Sciences' Brian Tang described the influence of climate change as making the “sponge even larger” when it comes to excess precipitation.
Experts assert that the findings of this analysis align with existing climate change expectations, warning that hurricanes like Melissa may become more commonplace in the future. Responses to this evolving climate crisis are essential to mitigate disasters that increasingly threaten lives and infrastructure across vulnerable regions.
