The people connecting last years hurricanes to global warming with any certainty were engaged in hyperbole. Very few atmospheric scientists (pretty much all of whom believe in anthrogenic global warming) were willing to make the connection and generally discounted it.
No individual piece of weather can be taken as a sign of climate. Even in the midst of a warming climate we'll have very cold winters. In the midst of a decades long drought there will still be big rain storms.
A stronger connection can be made between the warming and the strength of the hurricanes that did happen than between warming and the number of hurricanes that happened.
