Why Hurricanes Are Intensifying: Understanding the Growing Threat to Our Communities

Recent research shows that human-induced climate change has significantly intensified this year’s hurricanes. From Beryl to Rafael, scientists find that these storms have gained wind speeds due to rising ocean temperatures. An analysis by Climate Central highlights that between 2019 and 2023, climate change added an average of 18 mph to hurricane wind speeds, with over 80% of hurricanes during this period becoming notably more intense.

Warmer oceans act as fuel for hurricanes. The hotter the water, the more energy storms can absorb, resulting in stronger winds and heavier rainfall. This year’s hurricane season has been particularly destructive, with storms causing hundreds of billions in damages and over 300 fatalities.

Surprisingly, an 18 mph increase may seem minor, but it can elevate a storm from Category 4 to Category 5. This raises concerns among experts about the existing hurricane rating system. “With escalating storm intensity, we might need to consider a Category 6,” said Friederike Otto, a climatologist and co-founder of World Weather Attribution.

Notably, 2024 has already been declared the hottest year on record. Rising surface temperatures have made some hurricanes up to 800 times more likely due to human activity. For instance, Hurricane Rafael surged from Category 1 to Category 3, demonstrating how quickly conditions can shift. The rapid intensification of hurricanes like Milton, which saw winds increase by 90 mph in a single day, poses severe risks. Residents may misjudge storm strength, leaving them less time to prepare or evacuate.

Experts like Karthik Balaguru from the Pacific Northwest National Laboratory explain that shifts in wind patterns could decrease wind shear, a factor that helps limit hurricane strength. Rising humidity also contributes to this trend. Significantly, scientists have noted a surge in rapid intensification events near coastal areas in recent years.

The impacts of climate change on hurricanes are multifaceted and alarming. As the planet warms, the potential for stronger and more destructive storms increases. “We’re witnessing a new reality for hurricane intensity,” said Daniel Gilford from Climate Central. Continuous monitoring and research will be vital to understanding and preparing for the challenges that lie ahead.
