>Belize's Great Blue Hole is one of Earth's most mysterious features. Anyone peering into the 125 metre (410ft) deep pit will wonder what secrets and stories lie beneath. Now, scientists have discovered the natural oddity provides evidence of a concerning trend. A layered sediment core extracted from the bottom of the hole provides a 5,700-year storm archive – and it shows the weather is only getting worse. In 2022, researchers from Goethe University Frankfurt transported a drilling platform over the open sea to the Blue Hole, and then proceeded to extract a 30-metre sediment core from the underwater cave. Now, analysis reveals the layered sediment has served as an archive for extreme weather events for thousands of years, including tropical storms and hurricanes.
