From The Times:
Is the Atlantic Ocean in the midst of a long period of hyperactive hurricane seasons? Or have we entered a period of sedate storm seasons?
“That is the million dollar question right now,” said Jim Kossin, a climate scientist with the National Oceanic and Atmospheric Administration.
Every hurricane season brings the risk of destruction. But what’s at stake in this debate is how frequently residents along the Gulf of Mexico and the Eastern Seaboard will have to live with those risks in the coming decades.
Historically, the Atlantic Ocean has alternated between strong periods, during which hurricane seasons produce many storms and stronger storms, and sleepier times, characterized by seasons with fewer, weaker storms.
Ocean temperatures have trended warm ever since the 1990s. If those are the main drivers of ocean temperature fluctuation, Kossin said, that likely means an end to quieter, weaker storm seasons. Under that theory, 2017 could mark a continuation of this hyperactive period.
