Based on the results of the causality tests, the author concludes that it is global near - surface air temperature that influences sea surface temperature, and not the other way around — which supports the global warming - induced increase in hurricane intensity.
Thus, a decreasing pole - equator temperature gradient shouldn't have much effect on hurricanes.
There is virtually universal agreement that average hurricane intensity on Earth is a straightforward function of ocean - atmosphere temperatures; thus, rising SSTs will inevitably mean more intense hurricanes.
Considering that the mechanism of the «natural AMO» is so poorly understood, there's no justification for immediately blaming increases in hurricane activity on it while entirely ignoring global warming effects on sea surface temperatures (and atmospheric moisture), for which very clear mechanisms do exist.
But it does say; «Natural climate variations, which tend to involve localized changes in sea surface temperature, may have a larger effect on hurricane activity than the more uniform patterns of global warming...»
While the changes in both the mean and higher order statistical moments (e.g., variance) of time - series of climate variables affect the frequency of relatively simple extremes (e.g., extreme high daily or monthly temperatures, damaging winds), changes in the frequency of more complex extremes are based on changes in the occurrence of complex atmospheric phenomena (e.g., hurricanes, tornadoes, ice storms).

How hurricanes develop also depends on how the local atmosphere responds to changes in local sea surface temperatures, and this atmospheric response depends critically on the cause of the change.23, 24 For example, the atmosphere responds differently when local sea surface temperatures increase due to a local decrease of particulate pollution that allows more sunlight through to warm the ocean, versus when sea surface temperatures increase more uniformly around the world due to increased amounts of human - caused heat - trapping gases.25, 26,27,28
