Answer
There is an increase in the frequency of droughts and cyclones because-
In addition to triggering more rainfall, global warming could also increase the occurrence of drought.
The roots of both flooding and drought lie in the physical process known as evaporation.
As global warming heats the world’s oceans, the water molecules near the sea surface become more energetic and tend to evaporate into the atmosphere more readily. Thus, water vapour is formed.
Similarly, due to global warming, the number of cyclones in a year and their intensities have also increased in the tropical regions.
