When you have the largest Atlantic storm in recorded history that is being feed by unusually warm ocean waters (+5 °F) and is being steered in a very unusual direction by a «3 - sigma» blocking higher over Greenland after the largest Arctic sea ice melt in human history, you might want to consider the «steroid» hypothesis a bit more.
During Greenland summers, melting Arctic sea ice favors stronger and more frequent «blocking - high» pressure systems, which spin clockwise, stay largely in place and can block cold, dry Canadian air from reaching the island.
The paper uses evidence and modeling to explain how the sun - blocking impact from a 50 - year stretch of unusually intense eruptions of four tropical volcanoes caused sufficient cooling to produce a long - lasting shift in the generation and migration of Arctic Ocean sea ice, with substantial consequences for the Northern Hemisphere climate that lasted centuries and left a deep imprint on European history.

You say that there is evidence that AGW has caused the decline in arctic sea ice, which may be responsible for the changes seen in the paths of the jet stream, which may be responsible for the blocking high over Greenland which was responsible for Sandy's left turn.
Inside the Arctic the big factor is sea ice extent because that makes a huge difference by blocking radiative and evaporative cooling and not conducting particularly well either.
If that huge block of ice ever melted completely, sea levels would rise some 60 meters!
Lastly, even the record low Arctic ice levels may have influence over these types of storms by messing with the Jet Stream and blocking the storms from heading out to sea, instead shoving into the east coast.
Correction to the above: I should have said the ice in the Archipelago blocks cold Arctic sea water from leaving, thereby inhibiting the ingress of warmer southern water.

Cornell and Rutgers researchers report in the March issue of Oceanography that the severe loss of summertime Arctic sea ice - attributed to greenhouse warming - appears to enhance Northern Hemisphere jet stream meandering, intensify Arctic air mass invasions toward middle latitudes, and increase the frequency of atmospheric blocking events like the one that steered Hurricane Sandy west into the densely populated New York City area.
The study authors conclude that warming temperatures due to climate change are making it more difficult for ice arches to form every winter, preventing them from blocking the southward flow of sea ice.
«Being able to track and forecast the tracks of these huge blocks of ice will be a major benefit to the shipping industry, particularly as more ships begin to use polar waters, as Arctic sea ice melts.
I assume this lack of awareness was due to a lack of data on large sea ice loss seasons and lack of extreme events caused by blocking.
Strong winds blowing off the continent are pushing the giant floe away from its parent, the giant Pine Island Glacier, and the warming Southern Hemisphere's has melted the thick winter sea ice that held the block in place since July, said Grant Bigg, an ocean modeler at the University of Sheffield in the United Kingdom.
Yes, it appears none of this sea ice causes blocking appeared until after the IPCC was complete.
In their paper «Exploring recent trends in Northern Hemisphere blocking,» Barnes and colleagues used various meteorological definitions of «blocking» along with various datasets of atmospheric conditions to assess whether or not there have been any trends in the frequency of blocking events that could be tied to changes in global warming and / or the declines in Arctic sea ice.
The new study, along with other previously published research, showed that the decline in sea ice and snow cover has slowed the west - to - easterly component of the jet stream, thereby enhancing the north - to - south waviness of the jet, which leads to the creation of more stagnant or «blocked» weather patterns.
