Scientists have known climate change is increasing the severity of hurricanes for years now, but new research suggests it’s also leading to tropical cyclone clusters.

Hurricane - The term for tropical cyclones in either the Atlantic or Eastern Pacific basins which have maximum sustained winds of at least 74 mph.

The longstanding hurricane rating system, the Saffir-Simpson Scale, only takes into account sustained wind speeds and not the full devastating impact of a hurricane.

"The proportion of intense tropical cyclones (categories 4-5) is expected to increase at the global scale with increasing global warming," the WMO said in 2022, a message reiterated many times since.

Hurricane Erin formed on Friday, becoming the first hurricane of the 2025 Atlantic hurricane season. Now, all eyes are watching what this system does next as it treks just north of the Caribbean islands.

Hurricane Erin underwent rapid intensification and quickly strengthened into an extremely dangerous Category 5 hurricane at its peak intensity. Now, all eyes are watching what this system does next as it treks just north of the Caribbean islands.
