The Paris Agreement was adopted on 12 December 2015 at COP21. Its 10-year mark prompted a comprehensive review.

• Core goal: limit global average temperature rise to well below 2°C above pre-industrial levels, with efforts toward 1.5°C.
• Progress: global warming trajectory shifted from 4-5°C under pre-2015 policies to approximately 2-3°C with current pledges.
• Renewable revolution: solar and wind energy are now the cheapest sources of electricity in most countries. EV adoption reached nearly 20 per cent of global new car sales.
• India's achievement: 50 per cent of India's installed electricity capacity now comes from non-fossil fuel sources, achieved five years ahead of the 2030 target India had set for itself.
• International Solar Alliance: co-founded by India and France at COP21. Now has more than 120 member countries.
• Five priorities for the next decade: rising NDC ambition; ensuring just transitions for fossil-fuel-dependent communities; protecting natural carbon sinks (Amazon, Sundarbans); empowering non-state actors; science-based pathways aligned with IPCC projections.
• India's NDC: Net Zero by 2070; 500 GW of renewable capacity by 2030; 50 per cent of electricity from non-fossil sources by 2030 (achieved early).

The UN Convention Against Cybercrime opened for signatures in Hanoi, Vietnam. 72 of 193 UN member states signed.

• Significance: this is the first global cybercrime treaty in more than 20 years.
• Secretariat: United Nations Office on Drugs and Crime (UNODC).
• Entry into force: requires ratification by 40 countries.
• Coverage: illegal data interception, hacking, online money laundering, child sexual abuse material (CSAM) and cross-border electronic evidence sharing.
• India's decision: India participated in drafting but did not sign. Reasons include concerns about sovereignty (the treaty's evidence-sharing provisions could require India to disclose data to foreign agencies) and the broad surveillance powers the treaty enables signatories to exercise.
• India's cybercrime data (2023): cases increased 31.2 per cent to 86,420. Karnataka recorded the highest number. In January-May 2025 alone, Indians lost Rs 4,800 crore-plus to foreign cyber frauds.

Google's Willow quantum processor demonstrated the first verifiable quantum advantage for a specific practical computation.

• Willow specifications: 105 qubits.
• Achievement: completed a task in approximately two hours that Google estimated would take the world's fastest classical supercomputers several years.
• Algorithm used: Quantum Echoes, an algorithm measuring Out-of-Time-Order Correlators (OTOCs). This tests how quantum information scrambles through the system.
• Speed comparison: Willow executed the task 13,000 times faster than classical supercomputers.
• Key terms:
  • Qubit: the basic unit of quantum information, can exist in superposition of 0 and 1.
  • Entanglement: two qubits can be correlated so that measuring one instantly affects the other.
  • Quantum interference: quantum states can constructively or destructively interfere, amplifying correct answers.
• Applications on the horizon: molecular simulation (drug discovery), materials science, cryptography and financial optimisation.
• Willow's error correction: Willow demonstrated that adding more qubits to the processor reduced errors rather than amplifying them, a major breakthrough called "below-threshold" error correction.

GS area: Polity (Constitution, Judiciary)

A proposed Constitution (130th Amendment) Bill on ministerial accountability during detention entered public debate.

• Proposed amendment: Articles 75, 164 and 239AA would be amended. A Minister would stand removed from office if detained for 30 consecutive days.
• Offence threshold: the provision applies to offences punishable with five or more years of imprisonment.
• Scope: applies to the Prime Minister, Chief Ministers and all Union and State Ministers.
• Key legal principles in the debate:
  • Presumption of innocence: detention is not conviction.
  • Default bail under Section 187 BNSS (formerly Section 167 CrPC): if the investigation is incomplete within 60 to 90 days, a court must grant bail. The proposed 30-day threshold precedes this bail eligibility period.
  • Twin bail conditions under PMLA, NDPS Act and UAPA: these special statutes require the accused to satisfy two conditions before bail, showing non-guilt and showing non-likelihood of reoffending if released.
• Relevant cases: the Manish Sisodia case (bail granted after 17 months under PMLA) illustrates how long ministerial detention can last under special statutes.

The 8th General Assembly of the International Solar Alliance concluded at Bharat Mandapam, New Delhi.

• SUNRISE Initiative: Solar Upcycling Network for Recycling, Innovation and Stakeholder Engagement. Addresses the circular economy challenge of solar panel waste.
• One Sun One World One Grid (OSOWOG): regional solar energy interconnection plan. Links solar generation across Asia, the Middle East, Europe and Africa. Feasibility studies launched for 2-3 year timelines.
• SIDS Partnership: 16 Small Island Developing States signed MoUs with ISA and the World Bank for joint solar procurement. SIDS are among the most climate-vulnerable nations.
• Global Capability Centre: proposed as a "Silicon Valley for Solar" in India for R&D and innovation.
• India's solar capacity: 110.9 GW installed; ranked 3rd globally; record 23.83 GW added in 2024-25; solar PV manufacturing capacity grew 38-fold from 2.3 GW to 88 GW.
• Global clean energy investment 2024: USD 2.083 trillion; ISA member countries contributed USD 861.2 billion.

India's biosimilar sector was profiled ahead of the BioE3 policy implementation.

• Biosimilar definition: a biologic medicine that is highly similar to an already-approved reference biologic. Not a simple generic, biologics are complex proteins produced by living cells.
• Cost advantage: biosimilars cost 30 to 80 per cent less than the original biologic.
• FDA initiative: new draft guidelines would reduce development costs by USD 20-25 million and timelines from 5-7 years to 3-4 years.
• India's market share: under 5 per cent of the USD 30 billion global biosimilar market.
• Export projections: USD 0.8 billion currently; projected USD 4.2 billion by 2030 (4 per cent market share); USD 30-35 billion by 2047 at full potential.
• Key challenge: only 15 per cent of Indian biosimilars meet European Medicines Agency approval criteria, limiting access to high-value Western markets.

• Cyclone Montha landfall: the cyclone made landfall near Kakinada, Andhra Pradesh as a Severe Cyclonic Storm (wind speed 89-117 kmph). Coastal Andhra Pradesh, Odisha and Tamil Nadu received heavy rainfall.
• Koyla Shakti Dashboard: Ministry of Coal launched this unified real-time coal monitoring platform. Tracks production, transportation, supply and analytics. Companion system: CLAMP Portal for coal land acquisition, compensation and rehabilitation.
• India-France defence: discussions continued on a new Rafale fighter model development under Make in India. The plan covers 114 fighters for the IAF.
