In terms of the gold that a climate science denier might find in the paper, at the very least, they could argue that the fact that the troposphere isn't warming more quickly than the surface shows that the climate models are unreliable — even though the models predict just the pattern of warming that we see — with the troposphere warming more quickly than the surface over the ocean but less quickly than the surface over land.
Winter 2009 - 2010 showed a new connectivity between mid-latitude extreme cold and snowy weather events and changes in the wind patterns of the Arctic; the so - called Warm Arctic - Cold Continents pattern.
Even if it could be shown that climate is more sensitive to solar variability than the strict radiative forcing would suggest (along the lines of Shindell et al) one would still have to contend with the fact that we know the solar variability for the past fifty years quite well, and it does not do the kind of things necessary to give the present warming pattern.

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.
