Should There Be Category 6 Hurricanes?

Why It Matters

A Category 6 rating would improve risk communication and could trigger stronger climate‑adaptation policies and insurance reforms.

Key Takeaways

• Scientists propose adding Category 6 for storms exceeding 184 mph
• Category 5 currently caps at 157 mph, ignoring extreme winds altogether
• Typhoon Haiyan exemplifies devastation beyond Category 5 thresholds in the Philippines
• Research shows Category 6‑like storms rising in the last decade
• New rating could improve public warning and climate‑change communication

Summary

The video examines a growing call among climate scientists to introduce a Category 6 classification for hurricanes and typhoons whose sustained winds exceed 184 mph, a level currently lumped into the existing Category 5 bracket.

Researchers at National Taiwan University argue that the 157‑mph threshold no longer captures the upper tail of storm intensity, especially as a warming climate fuels faster winds. Their analysis shows a measurable uptick in storms surpassing 184 mph over the past ten years, and they cite Typhoon Haiyan (2013) – which caused thousands of deaths in the Philippines – as a case where the damage far outstripped what a Category 5 label would suggest.

“Category 6 storms have become more common in the past decade,” says atmospheric scientist Dr. Ein, adding that such storms can double the destructive potential compared with a typical Category 5. The current Saffir‑Simpson scale also omits rainfall and storm‑surge impacts, further understating risk.

Adding a Category 6 could sharpen public warnings, guide insurance pricing, and underscore the accelerating threat of climate‑driven extreme weather, prompting policymakers to prioritize mitigation and resilience measures.

An atmospheric scientist at the National Taiwan University says storms with winds above 184 miles an hour deserve their own category.
