Topic– Important Geophysical phenomena such as earthquakes, Tsunami, Volcanic activity, cyclone etc./ Disaster and disaster management.
4) The frequency of tropical cyclones has decreased ever so slightly over the last 70 years in the Indian Ocean season and Instead, a much higher frequency of high-intensity storms are being witnessed, in the light of recent onset of Cyclone Idai discuss role of human-induced climate change in such events.(250 words)
Why this question:
The question is in the backdrop of the Cyclone Idai that swept through Mozambique, Malawi and Zimbabwe over the past few days, the devastating cyclone that hit south-eastern Africa may be the worst ever disaster to strike the southern hemisphere.

Structure of the answer:
Begin with quoting the facts related to cyclone Idai; location, impact spread etc.
Discuss in brief what are cyclones, their impact in general, then move on to explain the current context of Idai cyclone.
Then justify why – The frequency of tropical cyclones has decreased ever so slightly over the last 70 years in the Indian Ocean season and Instead, a much higher frequency of high-intensity storms are being witnessed.
Discuss the role of climate change, mainly the human induce ones.
Suggest measures to tackle such incidences – disaster management, early detection etc.
Conclude with way forward – global efforts to tackle climate change and others.
