Ocean warming is fueling stronger hurricanes.
Hurricanes are blasting Bermuda with wind speeds that have more than doubled in strength over the last 66 years, due to rising ocean temperatures in the region as a result of
climate change, according to a new study.
Within a 62-mile (100 kilometers) radius of Bermuda,
the average maximum wind speed of hurricanes increased from 35 to 73 mph (56 to 117 km/h) between 1955 and 2019, the researchers found. This is the
equivalent of a 6 mph (10 km/h) increase every decade.During this time,
sea-surface temperatures in the region also increased by up to two degrees Fahrenheit (1.1 degrees Celsius), according to the Bermuda Atlantic Time Series (BATS), a long-running dataset collected by the Bermuda Institute of Ocean Sciences.
Scientists already knew that higher sea surface temperatures fuel stronger tropical cyclones. But the new findings show that
temperatures below the sea surface also play a key role in how these storms form.
