Research shows that extreme rainfall in West Africa is becoming more frequent.

On the 16th local time, the international research institution "World Weather Attribution Alliance" stated that due to the impact of global climate change, the probability of heavy rainfall in West Africa has greatly increased, about 5 times that of the period before the end of the 19th century. A research report released by the institution on that day pointed out that heavy rainfall lasting for three days was rare in West Africa in the past, but now it is expected to occur every two to four years, and the intensity of rainfall has significantly increased compared to the past.
