What the IPCC actually says....

From Martin Hoerling, a meteorologist at the National Oceanic and Atmospheric Administration focused on the forces influencing extreme weather (after Sandy):

http://dotearth.blogs.nytimes.com/2012/10/28/the-frankenstor...
"In this case, the immediate cause is most likely little more that the coincidental alignment of a tropical storm with an extratropical storm. Both frequent the west Atlantic in October…nothing unusual with that. On rare occasions their timing is such as to result in an interaction which can lead to an extreme event along the eastern seaboard. As to underlying causes, neither the frequency of tropical or extratropical cyclones over the North Atlantic are projected to appreciably change due to climate change, nor have there been indications of a change in their statistical behavior over this region in recent decades (see IPCC 2012 SREX report)."
[emphasis added]

From the IPCC 2012 SREX (Special Report on Extremes):
Increasing exposure of people and economic assets has been the major cause of the long- term increases in economic losses from weather- and climate-related disasters. Long-term trends in economic disaster losses adjusted for wealth and population increases have not been attributed to climate change, but a role for climate change has not been excluded....

Projected changes in climate extremes under different emissions scenarios5 generally do not strongly diverge in the coming two to three decades, but these signals are relatively small compared to natural climate variability over this time frame. Even the sign of projected changes in some climate extremes over this time frame is uncertain....

Long-term trends in economic disaster losses adjusted for wealth and population increases have not been attributed to climate change, but a role for climate change has not been excluded....

There is low confidence in any observed long-term (i.e., 40 years or more) increases in tropical cyclone activity (i.e., intensity, frequency, duration), after accounting for past changes in observing capabilities.
