Surge in hurricane activity is only a return to normal: study

Okay. I am baffled.
Ten days ago we had Kerry Emanuel quoted as saying "There has been a large upswing in the frequency of Atlantic hurricanes, beginning in 1995," Emanuel said on his Web site, http://wind.mit.edu/~emanuel/anthro2.htm. "This corresponds to an upswing in tropical North Atlantic sea surface temperature, which is very likely a response to increasing anthropogenic (human-caused) greenhouse gases." Source

Now PhysOrg has this " Investigators believe the greenhouse effect cannot be blamed for a surge in hurricane activity since the mid-1990s."
and
"The phase of enhanced hurricane activity since 1995 is not unusual compared to other periods of high hurricane activity in the record," they report on Thursday in Nature, the weekly British science journal.
