It was global warming in 2005...and 2006?

The multi-national gaggle of "scientists and bureaucrats" (now there's a fun combo for you) who covened in Paris for the Intergovernmental Panel on Climate Change say that "global warming has made stronger hurricanes, including those on the Atlantic Ocean such as 2005's Katrina".

Why then, is there no mention of the 2006 hurricane season, which only produced the paltry sum of five hurricanes (none of which went above Cat. 3 strength), and went by with nary a single Atlantic hurricane landfall on North America? If Katrina is evidence of global warming, then what, pray tell, was the '06 Atlantic (non) hurricane season evidence of?
