2. As global temperatures rise, permafrost is thawing at an accelerated rate, leading to a variety of environmental, social, and economic consequences. Examine. (250 words)

Difficulty level: Moderate

Reference: Down to Earth

Why the question:

Increasing temperatures thawing permafrost, exposing substantial quantities of organic carbon and atmospheric release of greenhouse gases.

Key Demand of the question:

To write about permafrost, its global distribution and impact of its thawing.

Directive word:

Examine – When asked to ‘Examine’, we must investigate the topic (content words) in detail, inspect it, investigate it and establish the key facts and issues related to the topic in question. While doing so we should explain why these facts and issues are important and their implications.

Structure of the answer:

Introduction: 

Begin by defining permafrost.

Body:

First, with a map, show the major areas of the world that are covered with permafrost.

Next, write about the thawing of permafrost under the impact of global warming.

Next, write about the impact of thawing of permafrost – Thawing permafrost can raise water levels in Earth’s oceans and increase erosion, resurrecting trapped pathogens, giving rise to potential public health threats etc.

Conclusion:

Conclude by writing a way forward to handle the above challenges.
