    About Ningaloo Reef  

    • Located in Western Australia.
    • A UNESCO World Heritage Site.
    • One of the largest fringing reefs in the world (~260 km long).
    • Important for marine biodiversity, supporting whale sharks, turtles, reef sharks, and diverse coral species.

    Extent of Coral Mortality

    • ~70% mortality recorded in latest survey.
    • In eight northern lagoon sites (Osprey → Tantabiddi Sanctuary Zones), mortality >60%.
    • Of 1,600+ corals assessed in March, only ~600 survived by October.

    Species Impact

    • Highly Affected (Dominant Species Lost)

        • Staghorn corals: Acropora tenuis, Acropora millepora and Acropora spicifera
        • Thin birdsnest coral (Seriatopora hystrix).
    • Relatively Resilient

      • Veron’s tube coral (Echinopora ashmorensis)
      • Lesser knob coral (Cyphastrea microphthalma)
    • Structural decline:
      • Dead corals now overgrown by sponges, turf algae, reducing reef stability & biodiversity.

    Broader Ecological Significance

    • Coral reefs support ~1/3 of global marine species.
    • Mass mortality compromises: Fish breeding grounds, Shelter for marine organisms, Coastal protection and Tourism & local economies.

    Widespread Global Coral Stress

    According to the United States National Oceanic and Atmospheric Administration (NOAA):

    • 84.4% of the world’s reef areas experienced bleaching-level heat stress (Jan 2023–Sept 2025).

  • Climate change is driven by human need and greed

    Introduction

    Climate change has long been discussed in terms of rising temperatures and carbon emissions, but historian Sunil Amrith reframes it as a moral and historical crisis. His work The Burning Earth explores how human ambition, industrialisation, and inequality have shaped the Anthropocene. The interview highlights that solving the crisis requires not just technology, but a transformation in values, governance, and global justice.

    Central Ideas and Dimensions

    1. Human Ambition and the Roots of the Climate Crisis
      1. Moral Dimension: Amrith draws from Mahatma Gandhi’s dictum, “The world has enough for everyone’s need but not enough for everyone’s greed.” Industrialisation, driven by greed rather than necessity, transformed humanity’s relationship with nature.
      2. Historical Continuity: Post-industrial societies viewed nature as a source of endless exploitation; colonised nations inherited these extractive systems.
      3. Colonial Legacy: European colonial powers intensified extraction in Asia and Africa, embedding global inequalities in resource use and emissions.
    2. Industrialisation and Technological Faith: A Limited Solution
      1. Technological Optimism: Many assume industrial progress can “fix” climate problems through innovation and decarbonisation.
      2. Historical Warning: Industrialisation was never morally neutral; it was driven by moral ambition and economic expansion.
      3. Inequality in Transition: The Global South is now being asked to decarbonise rapidly despite having contributed less to historical emissions.
      4. Example: The ‘Green Transition’ narrative often benefits rich economies while transferring economic burdens to poorer ones.
    3. Climate Change as a Political, not Merely Technical, Problem
      1. Political Process: Climate negotiations are shaped by historical responsibility and inequality in emission shares.
      2. Distribution of Responsibility: Developed countries hold disproportionate responsibility, yet developing countries bear heavier adaptation costs.
      3. Injustice of Geography: Those least responsible like communities in the Global South face the worst climate impacts.
      4. Global Debate: The question of who should pay and who should adapt is as pressing as the question of how to reduce emissions.
    4. Humanities and the Ethics of Climate Discourse
      1. Beyond Science: Amrith calls for humanities’ involvement, history, anthropology, and moral philosophy, to interpret climate change as a human story.
      2. Changing Relationship with Nature: Understanding industrialisation’s moral and emotional roots can help reshape our relationship with the planet.
      3. Broader Lens: Integrating social, cultural, and ethical frameworks prevents oversimplified “technological salvation” narratives.
    5. The Limits of Techno-fixes and the Role of Human Values
      1. Bill Gates’ View: Technology can solve climate change even if temperatures rise by 1.5°C.
      2. Amrith’s Counterpoint: Even if emissions stopped tomorrow, warming would continue due to locked-in carbon cycles.
      3. Moral Reorientation: Sustainable future demands restraint, compassion, and fairness, not mere efficiency or profit.
      4. Systemic Realisation: Human welfare, not human power, should guide policy; prosperity cannot be measured by GDP alone.

    Conclusion

    Amrith’s argument reframes the climate crisis as a mirror to human civilization reflecting not just carbon levels, but our collective morality. The path ahead demands ethical reawakening, equitable governance, and historical responsibility, not just green technology. Climate change is not a scientific failure; it is a civilizational test of whether humanity can outgrow its own greed.

    PYQ Relevance

    [UPSC 2024] Write a review on India’s climate commitments under the Paris Agreement (2015) and mention how these have been further strengthened in COP26 (2021). In this direction, how has the first Nationally Determined Contribution intended by India been updated in 2022? (Answer in 250 words)

    Linkage: The question builds directly on the Paris Agreement’s decade-long progress and India’s evolving role from commitment at Paris (2015) to enhanced ambition at COP26 and updated NDCs in 2022. This reflects the ongoing Paris to post-Paris transition architecture discussed in the article.

    Mentor’s Comment

    Ten years after the Paris Agreement, the world stands at a pivotal juncture. Despite unprecedented challenges, rising global temperatures, extreme weather, and persistent dependence on fossil fuels, the Paris framework has redefined multilateral climate cooperation. This article examines how the Paris Agreement has evolved into a transformative global instrument, its tangible outcomes, India’s role, and the emerging roadmap for climate justice and transition.

    Introduction

    Adopted at COP21 in 2015, the Paris Agreement marked a watershed in global climate diplomacy. It sought to limit global warming well below 2°C and ideally to 1.5°C above pre-industrial levels. A decade later, while emissions continue to rise and devastating consequences are visible, from floods in Uttarakhand and Punjab to glacial melt in Jammu & Kashmir. The Agreement has managed to bend the trajectory of warming from a catastrophic 4°C-5°C to approximately 2°C-3°C by the century’s end. This course correction, though insufficient, underscores that collective climate action works, and that multilateralism remains the only viable path to sustainable futures.

    Why in the News

    The year 2025 marks a decade of the Paris Agreement, a milestone being commemorated at COP30 in Belém, Brazil, where nations are reviewing global progress toward climate neutrality by 2050.

    What makes the Paris Agreement a Turning Point?

    1. Low Carbon Transition Catalyst: The Agreement has been instrumental in shifting the global economy from fossil fuels to renewable and efficient energy systems.
      • Example: Solar, wind, and hydroelectricity now anchor new job creation and green industries worldwide.
    2. End of Fossil Dominance: Ten years ago, fossil fuel use dominated energy production. Today, clean energy is mainstream, driven by technological and policy innovation.
    3. Global Policy Integration: The Paris framework integrates differentiated responsibilities, ensuring fairness for developing countries while enabling ambition from industrialised economies.

    How Has International Collaboration Strengthened Climate Action?

    1. International Solar Alliance (ISA): A joint initiative by India and France, launched at COP21, represents a symbol of cooperative multilateralism in climate governance.
      • Impact: Expanded to 120+ member countries, delivering results through capacity building, training, and renewable energy transitions.
      • Example: The 8th Assembly of the ISA in 2025 reaffirmed its mission of universal solar access and climate resilience.
    2. France-India Climate Partnership: Reinforced at the COP30 session, this partnership embodies shared leadership in sustainable energy and adaptation.

    How Has Climate Finance Evolved in the Last Decade?

    1. Predictable and Inclusive Finance: France and other EU members advocate for innovative, predictable climate finance through instruments like the Green Climate Fund and Loss and Damage Fund.
      • Example: One-third of France’s climate finance supports adaptation and early warning systems (CREWS).
    2. Global Solidarity Vision: At COP30, France emphasized “Global Solidarity Levers” ahead of 2030, urging equity in climate transition financing.
    3. Bridging the North-South Divide: The Paris framework institutionalized common but differentiated responsibilities (CBDR), making financial and technological flows more equitable.

    What Are the Emerging Priorities in the Climate Transition?

    1. Natural Carbon Sinks: Ecosystems like forests, mangroves, and oceans, from the Amazon to the Sundarbans, are recognized as vital allies in carbon sequestration.
      • Policy Implication: Strengthening biodiversity conservation underpins adaptation and mitigation goals.
    2. Empowerment of Non-State Actors: Climate progress now depends on the collective efforts of local governments, businesses, and citizens to translate ambition into implementation.
      • Example: Broad-based agreements post-COP21 enable tangible, community-level results.
    3. Science and Disinformation: The IPCC’s evidence-based advocacy remains central to the fight against climate misinformation, ensuring that policy aligns with scientific truth.

    What Lies Ahead?

    • Irreversibility of the Transition: The Paris transition cannot be reversed, it is now a necessity, not a choice.
    • Challenges Ahead: While adaptation and mitigation face obstacles, technological innovation, renewable investment, and inclusive policy frameworks are defining the next decade.

  • [28th October 2025] The Hindu Op-ed: A start for North-South carbon market cooperation

    PYQ Relevance

    [UPSC 2014] Should the pursuit of carbon credit and Clean Development Mechanism (CDM) set up under UNFCCC be maintained even though there has been a massive slide in the value of carbon credit? Discuss with respect to India’s energy needs for economic growth.

    Linkage: The CBAM-ICM linkage revives the same carbon market logic envisioned under the UNFCCC’s CDM. It aligns India’s emission pricing with global trade, ensuring growth and decarbonisation move together.

    Mentor’s Comment

    The EU-India partnership is entering a decisive phase with the linking of the Indian Carbon Market (ICM) to the EU’s Carbon Border Adjustment Mechanism (CBAM), a move that could redefine global climate cooperation. For the first time, carbon prices in India will be recognized at the EU border, preventing Indian exporters from facing double penalties and paving the way for North-South market integration. However, operational hurdles, technical mismatches, and sovereignty concerns remain significant.

    Why in the News

    Recently, the European Union (EU) and India announced a new comprehensive strategic agenda that includes linking the Indian Carbon Market (ICM) with the EU’s Carbon Border Adjustment Mechanism (CBAM). This is the first ever initiative to integrate a developing country’s carbon pricing mechanism with a developed region’s border carbon tax system. It marks a potential breakthrough in addressing carbon leakage, ensuring fair trade, and advancing global decarbonisation. But the success of this partnership depends on overcoming institutional, technical, and political challenges.

    Introduction

    India’s carbon market is still evolving, while the EU’s Emissions Trading System (ETS) is among the most advanced in the world. The decision to explore a linkage between India’s system and the EU’s CBAM represents a strategic step toward equitable carbon trade. This enables exporters to receive recognition for domestic carbon prices. However, the process involves complex alignment in regulatory design, pricing structures, and compliance verification. This makes this both a historic opportunity and a significant challenge for India’s climate diplomacy.

    What is the Current Status of India’s Carbon Market?

    1. Carbon Credit Trading Scheme (CCTS): India’s carbon market, under the CCTS, is still in its early stages of evolution.
    2. Institutional Framework: Built around robust auction structure, cap-setting processes, and independent verification, yet lacks full fledged coverage of sectors.
    3. Implementation Issues: Current credits often stem from project-based emissions reductions rather than comprehensive, economy wide mechanisms.
    4. Price Gap: The absence of a clear carbon price per tonne makes integration with CBAM technically difficult.
    5. Penalty Gaps: Without strong enforcement and penalties for non-compliance, credibility remains low.

    Why is Linking CBAM with ICM a Big Deal?

    1. Breakthrough for Indian Exporters: Linking ensures Indian exporters are not penalised twice, once through domestic carbon pricing and again at EU borders.
    2. Incentive for Early Decarbonisation: It rewards early climate compliance, encouraging Indian industries to adopt clean technologies.
    3. Global Policy Recognition: The move signals India’s emergence as a serious carbon market player. This gives legitimacy to its domestic emissions trading framework.
    4. Bridge between North and South: The linkage promotes North–South cooperation on climate action, addressing long-standing inequities in global carbon governance.

    What are the Major Challenges in Linking CBAM and ICM?

    1. Regulatory Equivalence: The EU will only deduct Indian carbon prices if market integrity and environmental standards match its ETS standards.
    2. Technical Alignment: Requires mirroring compliance-grade features of the EU ETS, a complex task for India’s bureaucratic and regulatory machinery.
    3. Carbon Price Disparity: The EU carbon price (currently €60-€80 per tonne) far exceeds India’s expected initial range (€5-€10 per tonne).
    4. Double Burden Risk: Exporters may face both EU CBAM costs and domestic compliance costs, raising fears of competitiveness loss.
    5. Political Sensitivity: Recognising EU’s CBAM could be seen as legitimising an external mechanism that India has formally resisted at WTO and COP negotiations.

    What are the Broader Strategic and Economic Implications?

    1. Trade and Diplomacy: Successful integration could make India a model developing economy for carbon-trade compatibility.
    2. Industrial Decarbonisation: Linking CBAM with ICM will push industries toward clean technologies, supporting India’s Net Zero 2070 target.
    3. Geopolitical Leverage: Creates space for climate diplomacy and green technology investments from Europe.
    4. Risk of Trade Disruptions: Failure to align standards could result in EU refusing deductions, escalating trade disputes.
    5. WTO Dimension: Any misalignment could destabilise trade flows, creating tension between climate goals and trade rules.

    What are the Possible Ways Forward?

    1. Institutional Strengthening: Develop a transparent, compliance-grade Indian carbon market mirroring the EU ETS structure.
    2. Pricing Reform: Establish comparable carbon price ranges and market stability mechanisms.
    3. Verification and Integrity: Set up independent verification systems recognized by EU regulators.
    4. Political Engagement: Maintain diplomatic negotiation channels to balance sovereignty with cooperation.
    5. Domestic Industry Support: Provide financial backing to exporters during transition to avoid competitiveness loss.

    Conclusion

    The EU-India carbon market linkage represents a defining experiment in global carbon governance. Its success will depend on institutional credibility, pricing comparability, and political balance. If executed effectively, it could become a template for future North–South cooperation, ensuring that climate responsibility is shared equitably and not imposed asymmetrically.
