It is well known that hurricane strength is directly proportional to the heat content of the waters which feed the storm; but there are plenty of sources for that heat. And of course, hurricanes are much more complicated than just that one element. The measured temperature changes are mainly not due to global warming, and that is the strength of this research. While the National Hurricane Center claims the increase in hurricane destructiveness since 1995 is due to “Atlantic Ocean fluctuations” it does not say what was fluctuating. This research shows it was mainly temperature, hence ocean warming is causing what is acknowledge to be a dramatic increase in hurricane destructiveness. The question then becomes, what caused the ocean warming.
