Cyclone numbers have fallen since start of 20th century, study suggests

Scientists warn that while total number of cyclones may be decreasing, global heating will see a higher proportion of more damaging storms

Global heating has coincided with fewer tropical cyclones forming each year around the globe compared with the second half of the 19th century, according to a new study.

The average annual number of cyclones fell by 13% across the 20th century, with steeper declines seen after 1950.
