WUWT's Bob Tisdale and Hurricane Joaquin

Anthony Watts finally put up an article about Hurricane Joaquin (archived here). It was from Bob Tisdale, one of the regular "guest" pseudo-scientists at WUWT. Bob thinks global warming is caused by a "blob" of warm water in the Pacific, or ENSO events. He has never tried to prove that. He just makes assertions. And he never tries to explain what caused the blob to appear, or why ENSO suddenly decided to heat up the world when it didn't for thousands of years. Bob's a hard-core denier of greenhouse warming and not good at logic (or evidence). Probably the only reason Anthony allowed him to mention Hurricane Joaquin was because it was another "it's not us" articles. In fact it was a very strange article altogether.

The point of Bob's article can probably best be summed up by this bit, where he wrote:
If history repeats itself, and it’s very likely to do so, alarmists will be claiming that Hurricane Joaquin is being made worse by oceans warmed by manmade greenhouse gases.

So far, the cause of the intensity of Joaquin is being attributed to the combined effect of very hot seas (some of the warmest on record in the region), and low-ish wind shear.  A weather underground tutorial on wind shear starts off by saying that "Wind shear is often the most critical factor controlling hurricane formation and destruction. " Below is the latest Earth Wind Map:
