The National Oceanic & Atmospheric Administration, U.S. Department of Commerce has posted an interesting release on hurricane trends which contains the following statement:
“This confluence of optimal ocean and atmosphere conditions has been known to produce increased tropical storm activity in multi-decadal (approximately 20-30 year) cycles. Because of this, NOAA expects a continuation of above-normal seasons for another decade or perhaps longer. NOAA’s research shows that this reoccurring cycle is the dominant climate factor that controls Atlantic hurricane activity. Any potentially weak signal associated with longer-term climate change appears to be a minor factor.”
In other words, what we are witnessing is part of a normal cycle.
