Q6. Explain the mechanisms through which oceans absorb and store atmospheric carbon dioxide. Discuss why regional disparities in data collection complicate climate modelling. (10 M)
Difficulty Level: Medium
Reference: DTE
Why the question Recent findings by UNESCO-IOC and assessments in IPCC AR6 highlight uncertainties in ocean carbon absorption, making it highly relevant for climate mitigation credibility and carbon budgeting debates. Key Demand of the question The question requires explaining the major physical and biological mechanisms through which oceans absorb and store carbon dioxide. It also demands analysing how regional disparities in data collection generate uncertainties in climate modelling and projections. Structure of the Answer: Introduction Briefly establish oceans as the largest active carbon sink and their regulatory role in maintaining atmospheric carbon balance. Body Mechanisms of ocean carbon absorption and storage – Indicate the role of the solubility pump and biological pump in enabling surface absorption and long-term sequestration. Impact of regional data disparities on climate modelling – Mention uneven monitoring in polar, coastal and deep-ocean regions leading to uncertainty in carbon budget estimations. Conclusion Conclude by linking comprehensive ocean monitoring and improved modelling to credible mitigation targets and realistic climate pathways.
