Although there is still some disagreement in the preliminary results (eg the description of polar ice caps), a lot of things appear to be quite robust as the climate models for instance indicate consistent
patterns of
surface warming and rainfall trends: the models tend to agree on a stronger
warming in the Arctic and stronger precipitation changes in the Topics (see crude examples for the SRES A1b scenarios given in Figures 1 & 2; Note, the degrees of freedom varies with latitude, so that the uncertainty of these estimates are greater near the poles).

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

warming that we see — with the troposphere
warming more quickly than the
surface over the ocean but less quickly than the
surface over land.

However, to support the assertion that global

patterns contributed to making Hurricane Sandy what it was — even if those factors can not be precisely quantified.

warmer than it would otherwise be, and the fact that through easily recognizable if [2] inadvertent growing
patterns we have at this point probably at least [3] doubled the total collective amount in heat absorption and re-radiation capacity of long lived atmospheric greenhouse gases (nearly doubling total that of the [4] leading one, carbon dioxide, in the modern era), to [5] levels not collectively seen on earth in several million years — levels that well predated the present ice age and extensive earth
