Hurricane Melissa: A Powerful Storm Amplified by Climate Change

Hurricane Melissa, demonstrating unprecedented strength as it devastated Jamaica, highlights the alarming impact of climate change on extreme weather events.

Hurricane Melissa, one of the strongest hurricanes recorded in the Atlantic, made landfall as a Category 5 storm in Jamaica, causing extensive damage. A recent study indicates that climate change significantly increased the likelihood and intensity of this storm, with warmer ocean temperatures playing a crucial role. As the Caribbean faces increasing hurricane threats, this event underscores the urgent need for climate action and resilience planning.

Hurricane Melissa: A Powerful Storm Amplified by Climate Change

Hurricane Melissa was one of the strongest hurricanes to ever hit the Caribbean.

The atmospheric and ocean conditions that contributed to the rapid intensification of the hurricane were made six times more likely by climate change, according to a World Weather Attribution study.

This storm quickly escalated from a tropical storm to a Category 4 hurricane within 24 hours, driven by unusually warm sea temperatures, and eventually struck Jamaica with the ferocity of a Category 5 hurricane. Following Jamaica, it made a second landfall in eastern Cuba.

Days before its landfall, meteorologists had indicated that conditions were ripe for rapid intensification, with parts of the Caribbean Sea approximately 1.5°C warmer than average. The high heat levels in the sea provided continuous warm water for Melissa's development, leading to maximum wind speeds increasing by 7% due to climate change.

As the storm wreaked havoc, it shed light on the interconnectedness of climate change and extreme weather. Insights from the Imperial College Storm Model noted that climate change amplified extreme rainfall associated with Melissa by 16%.

With hurricane season bringing more potent storms, the catastrophic impact of Hurricane Melissa is a reminder of the difficult and pressing challenges posed by climate change, particularly for vulnerable regions like the Caribbean.

This ongoing reality is underscored in the lead-up to COP30, the United Nations Climate Change conference to be held on November 10 in Belém, Brazil, highlighting the critical importance of immediate global climate action.
