In the context of which of the following do some scientists suggest the used of cirrus cloud thinning technique and the injection of sulphate aerosol into stratosphere?
Show answer
Answer: D. Reducing the global warming
Verdict
Correct answer: Reducing the global warming → Option (d).
Analysis
The geo-engineering technique known as stratospheric aerosol injection (SAI) could limit rising temperatures that are causing climate change.
Cloud thinning strategy would be used to shoot powder over cirrus clouds, which would thin out their coverage and alter their radiative effects over Earth.
Both techniques — cirrus cloud thinning and stratospheric aerosol injection — are proposed geo-engineering methods aimed at reducing global warming by reflecting more sunlight back into space or reducing the greenhouse effect.
