Hurricane cycles

Everybody has surely noticed the increase in recent years of the numbers of severe hurricanes. In fact, we have now surpassed the previous record of all tropical storms and hurricanes in this area of the world, as we have used up all the names on the prepared list, and have gone on to tropical storms Alpha and Beta. Those who deny the impact of global warming on the earth (who are often funded by the giant oil company Mobil-Exxon) quickly attributed this to a natural cycle of 25-30 years. Then a researcer looked at the data since 1970 (i.e., for the last 35 years), and found a large increase in the number of severe hurricanes in since 1990 that was unprecendented in the earlier years. Well, the resourceful natural cycle proponents immediately started talking about cycles of up to 50 years. If the data turns out to show that the last ten years has an unprecedented number of hurricanes since whenever, the natural cycle proponents will claim a longer cycle.
