Hurricane Melissa’s Devastation
Hurricane Melissa, a Category 5 hurricane, hit Jamaica on Tuesday, ripping through the Caribbean with winds of up to 300 km/h and causing widespread destruction. The hurricane also hit Haiti, the Dominican Republic, and Cuba, killing dozens of people.
Climate Change Impact
According to a study, climate change made Hurricane Melissa four times more likely. Researchers at Imperial College London estimated that in a world without climate change, a weaker hurricane would have caused about 12% less damage. They said human-caused global warming is increasing not only the intensity but also the likelihood of strong hurricanes.
Increased Wind Speed and Damage
Climate change increased Hurricane Melissa’s wind speed by 7% (11 miles per hour). In a cooler world without climate change, a Melissa-type hurricane would have made landfall in Jamaica once every 8,000 years. However, in today’s climate of 1.3°C warming, the likelihood has become four times more likely, with such an event now expected every 1,700 years.
Relief Efforts and Future Consequences
Jamaica now faces a huge relief effort to help a reported 400,000 people in a country where 70% of the population lives within 5km of the sea. Professor Ralf Toumi, director of the Grantham Institute, said, “Man-made climate change has clearly made Hurricane Melissa stronger and more destructive.” He warned that these storms will become even more devastating in the future if we continue to overheat the planet by burning fossil fuels.
Economic and Moral Imperatives
AccuWeather estimated that Melissa could cause $22 billion in damage and economic losses in Jamaica, and reconstruction could take a decade or longer. Co-author Dr. Emily Theokritoff emphasized the economic logic of reducing emissions now and the moral imperative to rapidly scale up international financing for loss, damage, and adaptation in the most vulnerable countries.
