उत्तर
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.
