Why this question:
The question is around the fact that goes undeniable – that the El Nino has been used to explain unusual climatic changes across the globe.
Key demand of the question:
Explain briefly the concept of El-Nino and its impact on the rare climatic events.
Structure of the answer:
Introduction:
In short, explain the concept of El-Nino.
Body:
El Nino means ‘little boy’ or ‘Christ child’ in Spanish. The phenomenon was thus named because it was first recognised by South American fishermen in the early part of the 17th century. The events, i.e., warm waters in the Pacific Ocean, tended to occur in December, hence, the name was chosen.
Then move on to define the likages of El-nino with climatic events.
When the linkage between El Nino and climate effects were initially suggested by the British scientist, Gilbert Walker, it was deemed ridiculous that one phenomenon could have an effect on regions as far off as Australia, India etc and Canada. However, the occurrence of El Nino in the past few decades has proved without a doubt, their far-reaching consequences. Some of the effects of El Nino in the past have been causing of droughts and forest fires in South Asia (Indonesia and Philippines) and Australia, floods in the South American countries in the eastern Pacific region, increased rain in certain other areas of the world etc.
Conclusion:
Conclude with significance of El-Nino.
