UPSC CURRENT AFFAIRS – 4 SEPTEMBER 2026

Context: The United Nations Environment Programme (UNEP) released a spotlight report titled “Limiting Overshoot: Navigating Exceedance of 1.5°C and Pathways Towards Return.”

• The report highlights that breaching the 5°C warming limit is now unavoidable in the near term, outlining an “overshoot, peak, and decline” framework to restore climate stability by 2100.

About UNEP Limiting Overshoot Report:

What is the Overshoot Framework?

• An overshoot pathway refers to a scenario where global average surface temperatures temporarily exceed the internationally agreed target (1.5°C) before peaking and gradually declining back below the limit through sustained net-negative emissions and deep decarbonization.

Key Findings in the Report:

• 1.5°C Threshold Nearing: Human-induced warming is nearing 1.4°C, rising at ~0.25°C per decade. WMO estimates a 75% chance that the 2026–2030 average will exceed 1.5°C.
• Shrinking Carbon Budget: Only about 130 GtCO₂ remains from 2026 for a 50% chance of limiting warming to 1.5°C. At current emissions (~40 GtCO₂ annually), it could be exhausted in about three years.
• Projected Warming: Current policies point to ~2.6°C warming by 2100. Even full implementation of NDCs and net-zero pledges could still result in peak warming of ~1.8°C.
• Cost of Delay: Every five years of sustained high emissions adds ~0.1°C to peak warming; reversing it would require removing about 220 GtCO₂.
• Ecological Tipping Points: Overshoot could trigger irreversible changes, including Greenland and West Antarctic ice-sheet loss, AMOC weakening and Amazon dieback.
• Cryosphere & Sea-Level Risks: Mountain glaciers could lose over 25% of their mass by 2100. Every century above 1.5°C could lock in ~40 cm additional sea-level rise by 2300.
• Socio-Economic Disruptions: Food production could fall by up to 14% by 2050 without adequate adaptation, while severe coral bleaching is pushing reefs beyond adaptation limits.
• Four-Stage Overshoot Pathway: An overshoot pathway is not a single event but a multi-decadal sequence across four distinct stages: Exceedance, Plateau/Peak, Decline, and Stabilization.

Positives Highlighted in the Report:

• Large Mitigation Potential: Available measures across energy, agriculture, industry and transport could cut up to 41 GtCO₂e annually by 2035, with nearly half costing below $20/tCO₂e.
• Health Co-Benefits: Rapid fossil-fuel phase-out could reduce SO₂ and NOx by 60–80%, lowering respiratory diseases and healthcare costs.
• Methane Reduction: Cutting methane, responsible for ~0.5°C of warming, offers one of the fastest ways to reduce near-term peak warming.
• Adaptation Pays: In developing economies, $1 invested in climate-resilient infrastructure can avoid about $4 in losses.
• Stronger Legal Precedents: International judicial rulings have strengthened 1.5°C-based due-diligence obligations for mitigation and adaptation.

Challenges Identified:

• Debt & Fiscal Stress: Climate-vulnerable countries face higher borrowing costs and rising reconstruction debt, reducing funds available for resilience.

Example: Around 70% of SIDS exceed the 40%-of-GDP debt threshold after repeated climate disasters.

• Limits of Carbon Removal: Nature-based CDR faces saturation and wildfire risks, while DACCS and BECCS require significant energy, water and land.

Example: Novel technological CDR contributes less than 0.1% of conventional removals.

• Maladaptation: Poorly designed adaptation can worsen ecological and social vulnerabilities.

Example: About 45% of Bonn Challenge restoration pledges involve commercial monocultures, which store far less carbon than native forests and can worsen water stress.

• SIDS Habitability Crisis: Sea-level rise and saltwater intrusion threaten freshwater, territory and statehood even before complete submergence.

Example: Tuvalu and Kiribati face substantial locked-in sea-level rise.

• Heat & Labour Productivity: Rising humid heat threatens human health and outdoor work.

Example: Labour capacity in Ghana could fall 11% at 3°C warming, while heat stress could drive 60–70% of projected GDP losses in Sri Lanka by 2053.

Recommendations:

• Integrate Mitigation & Adaptation: Pursue both simultaneously rather than treating them as competing priorities.
• Accelerate Decarbonisation: Rapidly phase down fossil fuels, expand renewables and sharply reduce methane emissions.
• Regulate Carbon Removal: Establish strong MRV frameworks and ensure CDR complements, rather than replaces, direct emission cuts.
• Transform Adaptation: Adopt flexible, climate-responsive infrastructure, nexus governance and planned retreat where necessary.
• Strengthen Loss & Damage Finance: Scale up the UNFCCC Fund for Responding to Loss and Damage before worsening climate impacts widen financing needs.

Conclusion:

A temporary 1.5°C overshoot may be increasingly difficult to avoid, but its scale and duration still matter. Every fraction of warming prevented can reduce irreversible ecological and human losses. Rapid decarbonisation, transformational adaptation and stronger climate finance are essential to return the world towards a safer temperature pathway.

Context: The Copyright Office of India rejected an application seeking to recognise the AI system DABUS as the author of an AI-generated artwork, while accepting that the work itself could satisfy the originality requirement.

About AI Creativity and Copyright:

What it is?

• AI creativity refers to the use of artificial intelligence systems to generate creative outputs such as images, music, literature, videos and designs.
• Under the Copyright Act, 1957, copyright protects original literary, dramatic, musical and artistic works. For a computer-generated work, Section 2(d)(vi) identifies the author as the “person who causes the work to be created.”

Arguments For and Against AI Authorship:

Significance:

• The ruling distinguishes originality from authorship. An AI-generated work may be original, but AI itself cannot currently be its statutory author; the legally responsible human may qualify as the person who “causes” the work to be created.
• It provides an important precedent for generative AI, intellectual property and creative industries, while leaving any extension of legal personhood or authorship to AI for Parliament to decide.

Relevance in UPSC Examination:

• GS Paper III: Artificial Intelligence, Intellectual Property Rights, IT and emerging technologies, innovation and digital economy.
• GS Paper IV: Ethical questions of creativity, accountability, ownership, responsibility and human agency in AI systems.
• Essay: AI and human creativity; technology and law; innovation versus accountability; future of human-machine relationships.

Context: Global bond markets are witnessing an intense sell-off that is pushing sovereign yields to multi-year highs across major economies.

• This development has spilled over into India, lifting its benchmark 10-year government bond yield and raising concerns over rising borrowing costs.

About The Global Bond Sell-Off:

What is the Global Bond Sell-Off?

• A global bond sell-off occurs when institutional investors simultaneously liquidate large volumes of government debt securities across major markets such as the US, UK, Germany, and Japan. This wave of selling floods the secondary market with excess supply, driving bond prices down and pushing market interest rates up.

Relationship Between Bond Prices and Yields:

Bond prices and yields share an inverse relationship:

• Market Dynamics: A bond’s face value and interest payout (coupon) remain fixed. When investors dump bonds, market supply outstrips demand, causing the market price of the bond to fall.
• Effective Return: When an investor acquires a bond at a discounted purchase price while receiving the original fixed coupon payout, the effective percentage return—the yield—rises automatically.

Key Reasons for the Global Sell-Off:

• Massive Sovereign Debt Issuance: Escalating US federal debt forces governments to issue vast quantities of new debt.
  • Investors demand higher risk premiums to absorb this supply glut, offloading older, lower-yielding securities in anticipation of higher-paying future issues.
• Persistent Inflation Pressures: Geopolitical tensions in West Asia and volatile crude oil prices have kept global inflation elevated, eroding the real purchasing power of fixed bond returns.
• Higher-for-Longer Interest Rate Expectations: With inflation remaining stubborn, markets expect central banks to keep benchmark interest rates elevated or hike them further, discouraging investors from holding low-yielding debt.

Implications for India and the Global Economy:

• As yields rise, governments must offer higher coupon rates on fresh debt auctions to attract buyers, increasing public debt-servicing burdens.
• Sovereign yields act as the risk-free benchmark for corporate debt. A climb in government yields pushes corporate bond interest rates higher, making capital expenditure and private borrowing more expensive.
• Higher borrowing rates compress corporate profit margins and prompt businesses to delay capital expansion plans, slowing overall economic growth.
• Rising yields on advanced-market debt often draw foreign portfolio investment (FPI) out of emerging markets like India, putting depreciation pressure on local currencies.

Context: The Supreme Court ruled that the Bar Council of India (BCI) and State Bar Councils possess no statutory power or jurisdiction to take disciplinary or punitive actions against law students.

About The Bar Council of India (BCI):

What It Is?

• The Bar Council of India (BCI) is a statutory, apex regulatory and representative body established by Parliament to oversee the legal profession and legal education in India.
• It prescribes uniform standards of professional conduct and etiquette for advocates, exercises disciplinary jurisdiction over the Bar, and inspects and recognizes universities whose law degrees qualify graduates for professional enrolment.

Established in: Formed under the authority of the Advocates Act, 1961, enacted by the Indian Parliament.

Historical Background:

• Post-Independence Need (1950): Following the commencement of the Constitution and the creation of the Supreme Court, legal and academic bodies, including the Inter-University Board and the Madras Provincial Lawyers Conference, called for a unified All-India Bar and common standards for legal examinations.
• The All-India Bar Committee (1951–1953): In August 1951, the Government of India constituted a Committee of Inquiry headed by Supreme Court Judge Justice S. R. Das. In March 1953, the committee recommended the creation of state bar councils and an apex national council to supervise the legal profession and legal education.
• Enactment (1961): Integrating the recommendations of the All-India Bar Committee and reports from the Law Commission of India, Parliament passed the comprehensive Advocates Act in 1961, establishing a unified bar.

Key Functions:

• Professional Standards & Discipline: Prescribes strict rules of professional conduct, etiquette, and decorum for enrolled advocates and exercises appellate disciplinary jurisdiction over State Bar Councils.
• Regulation of Legal Education: Establishes standards of legal education across universities in consultation with State Bar Councils and inspects institutions granting recognized law degrees.
• Recognition of Degrees: Accords recognition to Indian and foreign universities whose law degrees serve as valid qualification for enrolment as an advocate in India.
• Advocate Rights & Legal Aid: Safeguards the rights, privileges, and statutory interests of advocates, manages welfare funds, and organizes legal aid programs for underprivileged sections of society.
• All-India Bar Examination (AIBE): Administers the post-graduation professional qualification test mandatory for law graduates to obtain their certificate of practice.

Supreme Court Stand on BCI Powers:

• No Jurisdiction Over Students: The Supreme Court affirmed that under the Advocates Act, 1961, the BCI’s disciplinary and regulatory control begins only after a law graduate is officially enrolled as an advocate.
• University Autonomy: Disciplinary and administrative authority over law students rests exclusively with their parent educational institutions, universities, and respective university bylaws.
• Protection of Free Speech: The Court held that statutory regulators cannot penalize lawful dissent, run intimidation campaigns, or threaten to withhold professional enrolment simply because students exercise their constitutional rights to speech and peaceful protest.
