Why this question

“Hothouse earth” scenario was recently a buzzing topic  all across the global media. The public response has been triggered by a recent research on the topic, which has put forward a similar but more nuanced picture. It is hence essential to know about the concept as well its significance.

Directive word

Discuss- Discuss- This is an all-encompassing directive which mandates us to write in detail about the key demand of the question.

Critically analyze- Here we have to dig deep into the issue and identify and discuss about all the related and important aspects and correlate them to satisfy the key demand of the question.

Key demand of the question.

The question wants us to write in detail about the Hothouse Earth scenario. It then wants us to dig deep into the issue and discuss whether such a scenario is our destiny ( that can’t be avoided or can be avoided) or is it a mere speculation- i.e we have to analyze the veracity of the findings and then form an opinion on the issue.

Structure of the answer

Introduction- Write a few lines about the meaning and the significance of the term HE scenario. E.g mention that there is a threshold temperature above which the Earth Climate system would lose their feedback system, which keeps it cool, and a cascade of climate events will thrust the planet into a “hothouse” state. The threshold temperature is speculated to be 2 degree Celsius higher than the preindustrial levels, which could be reached at the turn of 2050 etc. Discuss the triggers that could lead to such scenario. Preferably draw the diagram as given in the article attached to the question.

Body-

  • Discuss the nuances involved in the findings. E.g it is an already familiar though in scientific circle which just got more media and public attention; the research is theoretical; the earth climate system is highly complex and unpredictable; human interventions or a major climatic event could change the possibility of the scenario etc.
  • Discuss the high possibility of a warmer earth with all its implications in the near future even though the scenario may not be as extreme as HE scenario.

Conclusion– stress upon the need to reduce our emissions, use sustainable technologies  etc in order to preserve our earth and its life etc.
