For the last half-century, we have rated hurricanes by an outdated<\/strong>, static, 5-tiered standard. Does this old framework give us fair warning of today’s record-breaking, super-charged cyclones?<\/p>\n

The world is warmer, and the oceans boil with even more fuel.<\/p>\n

Hurricanes are getting stronger than ever before<\/strong>, but they’re being trapped in the same old metric as always.<\/p>\n

Scientists want to completely rewrite how we evaluate and report extreme risks.<\/p>\n

Is it finally time to end this long history of failure?<\/strong><\/p>\n

Beyond the five-tiered limit<\/h2>\n

Saffir-Simpson was developed in the 1970s to identify what wind can destroy. It puts all wind damage into one of five ranks.<\/p>\n

This works well because most people know exactly what each level means.<\/strong><\/p>\n

However, there is a major flaw in the way this scale rates wind speed.<\/p>\n

It acts as a closed-ended protocol<\/strong>. It avoids words like “very high” or “extremely high.”<\/p>\n

In reality, it acts as an open-ended mechanism. When you reach the top grade, a Tier 5, that is where your ratings stop.<\/p>\n

A Tier 5 hurricane with 160mph winds is treated the same as one with 200mph. This doesn’t take into account the fact that wind power grows exponentially faster.<\/strong><\/p>\n

That growth causes catastrophic loss of human-made structures. Modern weather events are causing more damage than previously thought possible.<\/p>\n

Many were originally classified using the same criteria<\/strong> the system uses. By placing a cap on how we perceive these tempests, we may be downplaying their danger.<\/p>\n

A tale of two coasts: safety vs. growth<\/h2>\n

Florida views the use of a measurement system to inform their building code. If a developer believes that changing the way a hurricane is rated would cost him money, he will likely fight it.<\/p>\n

He would resist regulations that require his company<\/strong> to make changes based upon that changed evaluation.<\/p>\n

Developers often view regulatory costs as barriers to growth.<\/p>\n

On the other hand, cities near the ocean, especially cities in flood zones, see things differently<\/strong>.<\/p>\n

Florida fears wind-driven complacency if a new scale minimizes current dangers.<\/p>\n

Low-lying cities like New Orleans need a better scale because Saffir-Simpson ignores storm surge. They must plan accordingly for both surge protection and evacuation<\/strong> procedures.<\/p>\n

In addition, cities like New Orleans do not have the luxury to view updating their index as simply an academic exercise. <\/a>It is potentially lifesaving.<\/p>\n

The geographical features of a region play a significant<\/strong> role in determining how that region views risks.<\/p>\n

Redefining the danger zone<\/h2>\n

Research indicates that warming caused by humans has increased the number of extremely intense systems over time. This is highlighted in the study “The growing inadequacy of an open-ended Saffir\u2013Simpson hurricane wind scale in a warming world” published in Proceedings of the National Academy of Sciences<\/a>.<\/p>\n

Data also show that cyclones of the highest intensity have become<\/strong> increasingly common during this period.<\/p>\n

The current gauge cannot convey the serious threats presented by these new types of gales<\/a>.<\/p>\n

Therefore, experts believe that effective communication of risks<\/strong> should include accurate representations of hazard, exposure, and human vulnerability.<\/p>\n

A new tier for new threats<\/h2>\n

They propose this additional classification to represent storm intensities greater<\/strong> than 192 miles per hour. Adding a sixth tier would allow experts to express that our increasing global temperatures produce significantly stronger, deadly storms<\/a>.<\/p>\n

It would provide members of the general public with the language required to understand and respect<\/strong> extreme weather events.<\/p>\n

While this change is primarily about terminology, it ultimately relates to saving lives in affected communities.<\/p>\n

The world is moving faster than our old measurement tools<\/strong> can track. We must finally sharpen our focus to protect our future.<\/p>\n

It is time to rewrite our story before the next storm arrives<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
