{GS1 – Geo} Marine Heatwaves Amplify Tropical Cyclone

Context (DTE): Marine heatwaves (MHWs) act as high-octane fuel for tropical cyclones, producing storms far more destructive than typical cyclones.

MHWs occur when local sea-surface temperatures exceed the 90^th percentile of the historical baseline for at least 5 consecutive days.
Tropical cyclone is a warm-core, low-pressure, rapidly rotating storm system originating over tropical or subtropical waters. It becomes a hurricane or typhoon when sustained winds exceed 119 km/h.

Effects of Marine Heat Waves on Tropical Cyclones

Disaster Probability: Tropical cyclones passing over marine heatwaves are 1.6 times more likely to escalate into billion-dollar catastrophes (at least $1 billion in direct economic damage).
Economic Impact: MHW-influenced cyclones cause 93% higher economic damage than those passing over cooler waters.
Rapid Intensification: Marine heatwaves supply the thermal energy that increases the likelihood of rapid intensification (rise in wind speeds by at least 30 knots within 24 hours).
Precipitation Volume: Evaporation from MHW-heated surface waters produces 12% higher rainfall rates and more severe inland flooding.
Exposure Frequency: 52% of all landfalling tropical cyclones globally now pass over ocean regions experiencing heatwaves.
Regional Susceptibility: The North Indian Ocean, the Gulf of Mexico, and the Caribbean Sea have emerged as primary global hotspots for MHW-supercharged tropical cyclones.

How Marine Heat Waves Make Tropical Cyclones More Resilient?

Enthalpy Flux: Extreme sea-surface temperature gradients maximise combined sensible and latent heat transfer into the storm’s boundary layer.
Deep Thermocline: Heat penetrating deep into the water column prevents turbulence from churning up cooler water that would otherwise weaken the storm.
Thermodynamic Efficiency: Massive energy transfers trigger aggressive vertical air movement and a rapid drop in central pressure, accelerating wind speeds.
Vortex Stabilisation: Constant thermal inflow reinforces the storm’s eyewall structure against disruptive environmental forces such as wind shear.
Fuel Duration: Extended periods of high ocean temperatures provide a continuous supply of thermal fuel even as the cyclone traverses vast distances.
Ventilation Resistance: High internal energy levels prevent dry, cool air from penetrating and neutralising the storm’s warm core.

{GS2 – Polity} Recusal of a Judge

Context (IE): Delhi High Court heard a recusal plea by Arvind Kejriwal alleging bias against Justice Swarana Kanta Sharma in excise policy case proceedings.

What is the Recusal of a Judge?

Recusal refers to a situation where a judge withdraws from a case due to a conflict of interest or bias.
Objective: Ensures fair trial, judicial impartiality, and public confidence in the justice delivery system.
Legal Basis: Rooted in the principle that justice must not only be done but must also be seen to be done.
Types of Bias: Includes personal bias, financial interest, prior involvement, or ideological predisposition.
Reasonable Apprehension: Recusal may be triggered when there is a reasonable likelihood of bias in the mind of a fair-minded observer.

Legal Framework of Recusal of a Judge

No Codified Law: India has no specific provision governing recusal, making it largely judge-driven.
Nemo Judex Rule: Based on the doctrine “nemo judex in causa sua” (no one should be the judge in their own cause).
Judicial Precedents: The Supreme Court of India has developed principles of recusal through case law and conventions.
Judicial Discretion: Decision to recuse rests solely with the concerned judge, not parties.

Bangalore Principles of Judicial Conduct

Bangalore Principles of Judicial Conduct were adopted by the Judicial Group on Strengthening Judicial Integrity in 2002 and later endorsed by the United Nations in 2006.
It provides global non-binding guidelines to ensure transparency, accountability, and public confidence in the judiciary.

{GS2 – Governance} Criminalising Doping Networks in India **

Context (IE): India is shifting towards criminalising drug supply chains rather than only testing athletes through a World Anti-Doping Agency and CBI collaboration.

Operation Upstream is a global intelligence-driven initiative targeting the supply chain of doping substances rather than just athletes.
Led by WADA with agencies like the CBI, INTERPOL, and EUROPOL, using intelligence and investigations.
It has led to 250+ raids, 1.8 billion doses seized, and 88 illegal labs shut across 20 countries.

Anti-Doping Legal Framework in India

Doping in India is primarily governed by rules aligned with the WADA Code, making it a disciplinary offence, not a criminal crime.
National Anti-Doping Agency: NADA is responsible for testing, investigations, and imposing sanctions like suspension or bans on athletes.
National Anti-Doping Act, 2022: Provides statutory backing to anti-doping rules and establishes statutory authority for NADA.
Sanctions Framework: Penalties include suspension, disqualification of results, and fines, but do not involve imprisonment.
Gap in Criminal Law: There are no specific penal provisions to punish suppliers, traffickers, or support staff involved in doping under existing laws.

Proposed WADA–CBI Collaboration

Joint Enforcement: WADA will collaborate with CBI to investigate & dismantle doping networks in India.
Key Focus: Identifying and breaking production, trafficking, and distribution networks of performance-enhancing drugs (Operation Upstream).
Data & Surveillance: Emphasis on intelligence gathering, financial tracking, and coordinated investigations to tackle doping as organised crime.
Targeting Support Ecosystem: Coaches, physiotherapists, trainers, and suppliers involved in doping will be investigated and penalised.
Enabling Legal Framework: Collaboration will be effective only with proposed legal reforms under BNS to criminalise doping-related activities.

World Anti-Doping Agency

Establishment: WADA was established in 1999 to promote clean sport worldwide.
Fight Against Doping: Its primary aim is to detect, deter, and prevent doping in sports across all countries and disciplines.
Regulatory Framework: Issues the World Anti-Doping Code, which harmonises anti-doping rules, testing, and sanctions globally.
Functions:
- Testing & Monitoring: Oversees anti-doping testing, intelligence, research, and compliance of national bodies.
- Accreditation: Certifies laboratories for dope testing worldwide.
Enforcement Role: Increasing focus on intelligence-led investigations and tackling doping as organised crime (e.g., Operation Upstream).
