Part 4/5:
Upon analyzing this sediment, researchers revealed a concerning trend: the frequency of tropical cyclones in the Caribbean has significantly increased over the past 5,700 years. Historical data shows that between 4 and 16 storms passed over the Great Blue Hole each century. Alarmingly, in just the last 20 years, evidence indicates that nine tropical storms have occurred in that same area.
The scientists emphasize that climate change is exacerbating these events, with projections suggesting that up to 45 tropical cyclones and hurricanes could strike the Caribbean before the end of this century. As we explore the past through the sediments of the Great Blue Hole, we are also afforded a glimpse into the future—one that is far from hopeful.
