Something truly scary discovered at the bottom of Belize’s Great Blue Hole, revealing why more cyclones are predicted!
An expedition to the bottom of the Great Blue Hole off the coast of Belize in Central America has returned with a cargo of worrying information. After studying a 30-meter (98-foot) sediment core extracted from the floor of the sinkhole, scientists discovered that tropical cyclones have increased in frequency over the last 5,700 years. This trend is not only going to continue – it’s going to reach a fever pitch driven by a changing climate.
The team’s work involved carefully studying a core that covered the most recent 5,700 years of that history. In that timespan, the researchers identified 694 “event layers” that they attributed to tropical cyclones. With this data in hand, they were then able to piece together how cyclone frequency has changed over time.
The Great Blue Hole of Belize started its life as a limestone cave underground, an origin alluded to by the huge stalactites that can still be found in its depths. It became a sinkhole during the last glacial period, when its roof collapsed, subsequently flooding the cavity with water and transforming it into the thriving marine ecosystem it is today.
