Hurricane category 6 could be introduced under new storm severity scale

It’s my understanding that “category 5” means “total destruction”, which is why this hasn’t been done in the past. However if it helps to get the point across about climate change, it would be helpful for marketing purposes.

Sorry but that reason for a change feels very coercive. If cat 5 is intended to be total destruction, meaning that anything above the lower bounds for a cat 5 is indistinguishable, there should be no 6.

That's not what this is. (The person you're responding to didn't read the article.) They're not looking to add a "total-er destruction" category; they're looking to replace the current scale with one that takes into account more factors than just wind speed, such as storm surge and flooding. Under the current scale, a category 1 hurricane can be deadlier and more destructive than a higher-category hurricane. They want to use a different scale that better indicates the dangers. It goes up to 6 when multiple factors rate 5 on each factor's specific scale under the proposed system.

I think the title of this article is misleading and clickbaity. :/
