6. Critically analyse the potential of Geo-engineering as a climate change mitigation strategy. (250 words)
Difficulty level: Easy
Reference: Down to Earth
Why the question:
Some governments might decide to “geoengineer” the planet by spraying substances into the upper atmosphere to form fine reflective aerosols — a process known as stratospheric aerosol injection.
Key Demand of the question:
To analyse if Geo-engineering could be a viable option to overcome the climate crisis.
Critically analyse – When asked to analyse, you must examine methodically the structure or nature of the topic by separating it into component parts and present them in a summary. When ‘critically’ is suffixed or prefixed to a directive, one needs to look at the good and bad of the topic and give a fair judgement.
Structure of the answer:
Begin the answer by defining geo-engineering.
You can use a bubble diagram to show the various modes of geo-engineering such as Shoot Mirrors into Space (Solar Sunscreen), Copy a Volcano, Build Fake Trees etc.
In the first part of the body, write about how the above strategies work and will be beneficial for the planet above and over existing mitigation strategies to tide over the climate crisis. Clearly outline as to why it may be needed.
In the next part, mention about the major drawbacks, impediments and concerns regarding the implementation of the above strategies
End your answer that existing strategies should be implemented on a war footing, but alternative ideas must also be considered, planned and studied about just in case of a climate emergency.
