What is it about?

We introduce a hypothetical category 6 to the Saffir-Simpson Hurricane Wind Scale to convey the increased risk of very intense tropical storm due to climate change.

Why is it important?

Our message about the CAT6 paper is that climate change is making the strongest storms stronger. While the Saffir-Simpson scale is a convenient metric to express the increasing danger of tropical cyclones in changing climate, a single number is clearly inadequate to convey the risks of an impending storm. We have stressed to journalists that there are a variety of excellent NHC products that are much better than category to warn the public about the immediate risk of a hurricane. We note that the paper is open access and urge you to read our paper in order to better understand what we are trying to say

Perspectives

Dangerous climate change is already here. It is our problem, not only our grandchildrens'. Of particular danger is the increased danger from ever more powerful hurricanes.
