Southern Ocean Carbon Anomaly
- New research published in Nature Climate Change shows that the Southern Ocean has absorbed more carbon dioxide since the early 2000s, contrary to long-standing climate model predictions.
- This unexpected behaviour—termed a Southern Ocean carbon ‘anomaly’—reveals key processes that climate models have so far underrepresented.
About Southern Ocean Carbon Anomaly:
- The Southern Ocean carbon anomaly refers to the observed strengthening of the Southern Ocean as a carbon sink, even though climate models predicted it would weaken and start releasing carbon dioxide under global warming.
- Instead of emitting more CO₂ due to stronger winds and upwelling, the ocean has continued to absorb an increasing share of human-emitted carbon.
How it occurs?
- Strengthened westerly winds drive upwelling: Climate warming intensifies Southern Hemisphere westerlies, pulling carbon-rich deep waters upward toward the Southern Ocean surface.
- Freshwater input lightens surface layers: Increased Antarctic ice melt and rainfall add freshwater at the surface, making it less salty and more buoyant.
- Stratification forms a surface “lid”: The buoyant freshwater layer strengthens vertical stratification, separating surface waters from deeper, carbon-rich layers.
- Blocked air-sea gas exchange: Although deep waters rise, stratification prevents them from reaching the surface, stopping CO₂ from escaping to the atmosphere.
- Carbon gets trapped below the surface: Upwelled circumpolar deep waters remain approx. 100–200 m below the surface, allowing continued net carbon absorption.
- Small-scale processes amplify the effect: Ocean eddies and ice-shelf cavity dynamics reinforce stratification but are poorly resolved in coarse climate models.
Factors causing the anomaly
- Freshening of surface waters: Increased rainfall and meltwater from Antarctic glaciers have reduced surface salinity, making surface waters lighter and more buoyant.
- Enhanced stratification: Fresher, lighter surface layers sit atop warmer, saltier deep waters, limiting vertical mixing and air-sea gas exchange.
- Trapping of carbon-rich waters below surface: Upwelled circumpolar deep waters remain 100–200 metres below the surface, preventing CO₂ release.
- Incomplete model representation: Climate models struggled to capture small-scale processes such as ocean eddies and ice-shelf cavity dynamics that govern stratification.
- Data limitations: Sparse, seasonal observations in the Southern Ocean reduced the ability to validate and refine model behaviour.
Implications of the anomaly
- Temporary climate buffer: Continued carbon uptake has slowed the accumulation of atmospheric CO₂, buying the world limited time.
- Risk of sudden reversal: Observations suggest surface stratification is thinning; if it collapses, stored deep carbon could rapidly outgas.
- Model refinement imperative: Highlights the need to better integrate ocean chemistry, freshwater inputs, and fine-scale physics into climate models.
- Policy relevance: Reinforces that reliance on natural carbon sinks is risky and cannot substitute for emission reductions.
- Importance of sustained observation: Year-round monitoring of polar oceans is essential to anticipate abrupt climate feedbacks.
Conclusion
- The Southern Ocean carbon anomaly shows that nature can temporarily defy model expectations, but not indefinitely. Freshwater-driven stratification has masked deeper vulnerabilities in the climate system. As this protective layer weakens, the Southern Ocean could swiftly shift from carbon ally to climate amplifier, underscoring the urgency of emissions cuts and better observations.

Report on ‘Self-Reliance in Minerals and Metals’
- Standing Committee on Coal, Mines and Steel Presents Report on ‘Self-Reliance in Minerals and Metals’
- The report outlines a roadmap for India to reduce import dependency and achieve the vision of Atmanirbhar Bharat and Viksit Bharat.
Self-Sufficiency Levels in Minerals and Metals:
- India is largely self-sufficient in key industrial minerals like bauxite, chromite, iron ore, kyanite, limestone and sillimanite.
- However, certain minerals, such as magnesite, manganese ore, and rock phosphate, are deficient and must be imported to meet domestic demand.
- India is 100% dependent on imports for vital minerals such as lithium, Cobalt, and Nickel.
Key challenges in achieving Self-Sufficiency
- Operational Delays: Out of 486 mineral blocks auctioned since 2015, only 63 are operational. Mining projects face long gestation periods of about 5 to 14.5 years.
- Technology Gap: India lags global standards in automation, AI and IoT use in mining, which raises costs and limits exploration intensity.
- Exploration Constraints: Only about 15% of India’s area has been covered by detailed exploration, mostly focusing on surface deposits rather than deep-seated ones.
Key Recommendations
- Urban Mining & Circular Economy: The committee recommends a focus on recovering minerals from e-waste, industrial scrap, and EV batteries.
- Inter-Ministerial Coordination: Suggests setting up an Inter-Ministerial Group to fast-track post-auction progress and statutory clearances for critical mineral projects.
- Public-Private Collaboration: Encourages leveraging the strengths of Public Sector Undertakings (PSUs) and private sector expertise for faster exploration and processing development.
- Upskilling: Recommends that mining companies allocate a percentage of CSR funds for upskilling the workforce to handle advanced technologies like AI and automation.
Policy Framework for Self-Reliance
- Mines and Minerals (Development and Regulation) (MMDR) Act Amendments (2015-2023): Key reforms include the introduction of transparent e-auctions, uniform 50-year lease periods, and a new Exploration Licence (EL) category for 29 deep-seated and critical minerals.
- National Critical Mineral Mission (NCMM): Launched in 2025, this mission aims to secure the supply chain for 30 identified critical minerals.
- Overseas Acquisitions: Through KABIL (a joint venture of NALCO, HCL, and MECL), India is actively pursuing mineral assets in resource-rich nations like Argentina, Chile, and Australia.
- Offshore Mining: In 2024, the government launched the first tranche of 13 offshore mineral blocks for auction, targeting construction sand and polymetallic nodules.
Reviving Shipbuilding in India
- Shipbuilding is known as mother of heavy engineering as it enhances national security, strategic independence, and the resilience of trade and energy supply chains.
Current Status of Shipbuilding in India
- Shipbuilding industry accounts for less than 1% of the global shipping market.
- China has the biggest shipbuilding capacity in the world, followed by South Korea and Japan.
- Foreign ships carry 92% of India’s total trade and are paid $75 billion annually for it.
- Cochin Shipyard has India’s highest capacity in shipbuilding and repairing.
Challenges faced by Sector
- High capital costs: Due to expensive financing options available, making large investments risky and limiting shipyards’ ability to scale.
- Import dependence: Lack of indigenous availability of many advanced materials and components.
- Lower productivity: Compared with China, Indian shipyards are less productive, often due to outdated technology, longer build times, Supply chain limitations, etc.
- Strengthening India’s shipbuilding sector is vital to transforming India into a global maritime and shipbuilding hub by 2047
Key Initiatives taken to promote Shipbuilding in India
- Financial Assistance: Shipbuilding Financial Assistance Scheme, Maritime Development Fund.
- Public Procurement Preference: Ships under ₹200 crore must be procured from Indian shipyards as per the Make in India Order, 2017.
