4. The contribution of a melting ice sheets covering West Antarctica and Greenland leading to sea-level rise be significant and challenging to entire globe and humanity. Discuss. (250 words)

Reference: The Hindu 

Why this question:

Scientists have warned that oceans are likely to rise as much as 1.3 metres by 2100 if the Earth’s surface warms another 3.5 degrees Celsius.

Key demand of the question:

One must discuss in detail the increasing Global warming has led to the melting of the icesheets in Antarctica, Greenland and Arctic leading to rise in sea levels. Further one must explain the ill effects it poses to humans, biodiversity etc. Provide the measures that needs to be taken.

Directive:

Discuss – This is an all-encompassing directive – you have to debate on paper by going through the details of the issues concerned by examining each one of them. You have to give reasons for both for and against arguments.

Structure of the answer:

Introduction:

In brief explain the scenario of how global warming and increasing emission of GHGs has led to rise in earth’s mean temperature.

Body:

Explain the process of how ice sheet melting and the factors that are leading to rise in sealevel water rise.

Explain in detail the effects of this melting of ice sheets.

  • This will redraw the planet’s coastlines.
  • About ten percent of the world’s population today live on land less than five metres above the high tide line, who will be climate migrants.

Discuss the initiatives taken across Globe to curb these ill-effects.

Suggest measures on how to control the ice sheet melting.

Conclusion:

Conclude with a way forward.
