5. With suitable examples discuss the human perturbation to carbon cycle. (250 words)

Reference: Science Daily

Why the question:

The question is based on the impact of humans on Carbon Cycle.

Key Demand of the question:

With suitable examples discuss the human perturbation to carbon cycle.

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:

The human perturbation of the carbon cycle is driven by the combustion of fossil fuels and changes in land use and land use intensity.

Body:

The current climate crisis underlines that carbon cycle perturbations can cause significant climate change.

Discuss the sources of carbon gases that are human activities based such as agriculture; Agriculture is the major source of greenhouse gases to the atmosphere from human activities not accounted in the global C-CO2 budget, and contributing to 10-12% of total anthropogenic GHG emissions.

The global anthropogenic CO2 perturbation leads to the creation of carbon sinks in the ocean and on land. The physical ocean responds to excess atmospheric CO2 through increased air-to-sea fluxes by dissolution of CO2 in surface water given the under-saturation state of the ocean.

Suggest what needs to be done.

Conclusion:

Conclude with way forward.
