Hurricane Melissa recently slammed into Jamaica, making history as one of the most powerful storms ever recorded. A new study finds that climate change, driven by human activities, made this storm four times more likely to happen.
Researchers from Imperial College London discovered that warmer global temperatures—primarily from burning fossil fuels—intensified Hurricane Melissa, pushing it to Category 5 strength. Ralf Toumi, director of the Grantham Institute, noted that while Jamaica was somewhat prepared, there are limits to how much adaptation can help. “Adaptation is crucial, but we must also cut greenhouse gas emissions,” he emphasized.
Using a model that simulates storm paths, scientists determined that in a cooler climate, a hurricane like Melissa would hit Jamaica only once every 8,100 years. Now, that frequency has increased to every 1,700 years due to climate change. Currently, the planet is 1.3°C warmer than pre-industrial levels, nearing the critical 1.5°C threshold that scientists warn we must avoid to prevent severe climate consequences.
A chilling statistic shows that if we reach a 2°C increase, wind speeds from storms like Melissa could increase by 26 kilometers per hour. As it stands, Melissa brought winds of up to 295 kilometers per hour and caused massive rainfall of about 76 centimeters.
Toumi remarked, “Human-caused climate change clearly made Hurricane Melissa more powerful.” He warns that, without action, storms will continue to worsen.
However, the extent of destruction caused by Melissa was so significant that even stronger storms might not result in much additional damage, according to the study. The researchers faced challenges accessing satellite data due to a U.S. government shutdown, which limited their ability to study the storm’s rainfall impact.
Estimates from Enki Research put the direct damage at around $7.7 billion, roughly 40% of Jamaica’s GDP, and recovery is expected to take at least a decade. This figure doesn’t account for broader economic impacts like loss of tourism and shipping, which could amount to many billions more.
As we reflect on this event, it’s essential to recognize the ongoing risks posed by climate change. According to a recent survey by the Pew Research Center, over 60% of Americans are concerned about climate change affecting weather patterns in their areas. As storms grow fiercer and more frequent, it’s clear that we need both urgent action on emissions and robust strategies for adaptation.
