The way you have presented this data likely understates the increase that has occurred since 1950. I would think that if the numbers were broken out in decades, the trend upwards would be more obvious although there might be some fluctuations, decade to decade.
I wanted to compare data after 2007 report (which probably didn't use 2005/2006? data). Not sure whether data prior to satelites ~1979 is consistent data so that was broken off.
But if you want it a different way:
Pacific Typoon basin is much more consistent with IPCC predictions.

Basically more variabilty shown (no surprise) and not much trend apart perhaps in Super Typhoons but there the numbers are low.
These numbers don't mean much. But so far it is not looking like a resounding success for these 2 IPCC predictions.
