GS Paper 1: Geography & Disaster Management

UPSC's GS Paper 1 questions since 2016 →

Super El Niño to Add 15,800 Heat Deaths in India

Why in news: A Climate Impact Lab report projects about 15,800 additional heat-related deaths in India between September 2026 and February 2027, as a Super El Niño drives unusually high temperatures even as the monsoon withdraws with a rainfall deficit.

For Mains: Frame this as anthropogenic climate change amplifying a natural ENSO cycle (GS1 Geography/GS3 Disaster Management), and link it to India's Heat Action Plans and NDMA heat-wave guidelines when answering on climate-linked public-health risk. What counts as El Niño: Unusual warming of sea-surface temperatures in the central and eastern equatorial Pacific, now over 3°C above normal; the IMD tracks it via the Niño 3.4 index, declaring an event once anomalies exceed +0.5°C for five overlapping three-month periods.

GS Paper 2: Polity, Governance & International Relations

UPSC's GS Paper 2 questions since 2016 →

SC's Split Verdict: Why the CEC Selection Panel ‘Fails the Perception Test’

Why in news: In a split verdict on the 2023 law governing the appointment of the CEC and ECs, Justice Dipankar Datta held that replacing the CJI with a Union Minister on the selection panel fails the “perception test,” and separately defended the judicial Collegium against the government's criticism.

For Mains: Use for the 'basic structure' test of ECI independence (Article 324) — that an institution must not just be independent but must appear independent — and for the tension between parliamentary sovereignty (the 2023 Act) and judicial review (Anoop Baranwal).

Anti-Defection Law and the Speaker's ‘Amphibious’ Role

Why in news: The Supreme Court declined to fix a timeline for Lok Sabha Speaker Om Birla to decide disqualification pleas against 20 rebel Trinamool MPs, reviving the debate on the Speaker's dual role under the Tenth Schedule.

For Mains: Use to critique the Speaker's conflict of interest as a ruling-party nominee adjudicating defection pleas, and cite reform proposals (Dinesh Goswami Committee, Law Commission's 170th Report) for shifting this power to an independent body.

India and the EU Finally Set a Date: FTA Signing on December 16

Why in news: India and the European Union will sign their long-negotiated Free Trade Agreement on December 16, 2026, in Brussels — a deal both sides call the “mother of all deals.”

For Mains: Use as a case study on bilateral FTAs versus stalled mega-regional deals (contrast with India's RCEP exit), and on India diversifying export markets in response to U.S. tariff and sanctions pressure.

India Rejects OIC Group's Remarks on Kashmir

Why in news: India categorically rejected references to Jammu and Kashmir in a joint communiqué of the OIC's Contact Group on J&K, calling the group's remarks “politically motivated propaganda.”

For Mains: Cite this as India's 'no third-party mediation' doctrine on Kashmir (rooted in the Shimla Agreement, 1972), and contrast India's rejection of the OIC as a bloc with its parallel bilateral outreach to individual OIC members such as the UAE and Saudi Arabia.

Delhi's Coaching-Centre and PG Ecosystem: A Governance Blind Spot

Why in news: A Vidhi Centre analysis flags how Delhi's crowded Paying-Guest (PG) and coaching-centre ecosystem operates in a regulatory grey zone, with no dedicated safety standards despite repeated infrastructural tragedies.

For Mains: Link this to the 74th Constitutional Amendment's incomplete devolution of planning powers to urban local bodies, and to the wider governance gap between static master plans and fast-changing land use in Indian cities.

Explainer: How Motor Accident Compensation Is Computed

Why in news: With India recording the world's highest road fatalities, a Hindu explainer breaks down how Motor Accidents Claims Tribunals compute “just” compensation under a formula the Supreme Court built through Sarla Verma (2009) and Pranay Sethi (2017).

For Mains: Cite Sarla Verma (2009) and Pranay Sethi (2017) as judicial law-making filling a legislative gap in 'just compensation' under Section 168, and link to GS3's road-safety theme via the Sundar Committee's recommendations.

GS Paper 3: Economy, Science & Technology

UPSC's GS Paper 3 questions since 2016 →

Quality Control Orders: Balancing Standards with MSME Manufacturing

Why in news: A CSEP study finds that Quality Control Orders on intermediate inputs like chemicals lift large firms' output but cut smaller firms' profitability by nearly half, as the government weighs the next phase of QCO rationalisation.

For Mains: Use as a trade-off between 'Make in India' quality upgrading and MSME competitiveness, and connect to repeated Economic Survey calls for calibrated, sector-specific QCOs rather than blanket coverage.

Railways Commission Kavach 4.0 for the First Time on South Central Railway

Why in news: Indian Railways rolled out its upgraded, indigenous Automatic Train Protection system, Kavach 4.0, for the first time on South Central Railway's Malkajgiri-Kamareddi section, a step toward network-wide safety modernisation.

For Mains: Cite Kavach under 'indigenisation of critical safety technology' (Make in India, GS3 S&T), and pair it with recent train-collision debates on India's railway safety infrastructure gaps.

AI's Advance into Mathematics: Opportunity, Risk, and India's Place

Why in news: A wave of AI-generated proofs — including a solution to the Navier-Stokes Millennium Prize Problem — has forced mathematicians to confront how AI reasoning is reshaping scientific research and its governance.

For Mains: Use for GS3 essays on 'AI governance and scientific research' — balancing innovation incentives for AI labs against transparency, reproducibility, and equitable global access to frontier models.

GS Paper 4: Ethics, Integrity and Aptitude

UPSC's GS Paper 4 questions since 2016 →

A Judge's Resignation from Maharashtra's UCC Panel: Conscience vs Institutional Loyalty

Why in news: Retired Bombay High Court judge R.C. Chavan resigned from Maharashtra's Uniform Civil Code drafting panel, objecting to reducing complex social questions to a binary “yes/no” public-feedback format — a classic dilemma in public-service ethics.

For Mains: Use this case to discuss when resignation, internal reform, or public dissent- while-serving is the more ethical response to a flawed institutional process — a recurring GS4 theme in probity and public-service values. MAINS CASE STUDY EXERCISE Q. You are a domain expert appointed to a government committee tasked with building public consensus on a sensitive social reform.
