On the global warming context, it's worth noting that while sea surface temperatures are hot, a more important factor for hurricane intensification (among many) is «tropical cyclone heat potential» (which includes the temperature of deeper layers of seawater that get churned up as a tropical storm passes).

With respect to 181, if global warming increases sea surface temperatures which contribute to an intensification of tropical cyclones, then storms with winds below hurricane intensity will more frequently attain hurricane status (~ 100 kph winds).

There are certainly better indicators of global warming trends — ice sheet volume, sea ice extent and sea surface temperatures all come to mind — but hurricanes get people's attention.

The higher sea surface temperatures in the tropics (~ 0.85 K / decade in recent decades) have lead to an increase in LW (infrared) radiation, and a loss to space of some 3 W / m2 all over the tropics (50 % of the surface), which more than halves the — theoretical — global influence (~ 2.4 W / m2) of all extra GHGs together since the start of the industrial revolution.

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

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.

Seems to me the debate about AGHG global warming and increasing TC frequency / intensity / duration boils down to the fact that as sea surface temperatures, as well as deeper water temperatures rise, the wallop of any TC over warmer seas without mitigating circumstances like wind sheer and dry air off land masses entrained in the cyclone will likely be much more devastating.

However, to support the assertion that global warming is responsible for a great deal of damage from such events, it is sufficient to show that such events have the «signature» of global warming — for example, that specific global warming - related factors such as abnormally high sea surface temperatures, elevated water vapor levels, and altered jet stream patterns contributed to making Hurricane Sandy what it was — even if those factors can not be precisely quantified.

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.
