Supreme Court Notice on Climate Induced Heat Wave Deaths
Source:The Hindu ↗
Why It Matters
This issue represents a crucial convergence of constitutional law and environmental disaster management. It illustrates how the Indian judiciary is increasingly treating the adverse impacts of climate change, such as fatal heat waves, as a fundamental rights issue that requires proactive disaster mitigation and accountable governance.
Summary
The Supreme Court has issued a notice to the Union government regarding a public interest litigation on mounting heat wave deaths across India. Citing the SC's previous landmark ruling in the M.K. Ranjitsinh case, the petitioner argued that the failure to protect citizens from climate-induced extreme heat violates fundamental rights under Articles 14 and 21. The petition underscored a widespread failure by state governments to implement the National Disaster Management Authority's (NDMA) 2019 guidelines on Heat Action Plans. Relying on IMD data showing the spatial expansion of heat waves and IPCC reports on escalating climate risks, the plea calls for urgent government accountability under the Disaster Management Act and Environment (Protection) Act.
Key Points
- The Supreme Court is reviewing the government's response to rising heat wave deaths, framing climate change impacts as a potential violation of the fundamental right to life (Article 21).
- A petition highlighted the failure of state governments to properly implement the NDMA's 2019 National Guidelines on Heat Action Plans.
- The IMD reports that severe heat waves have geographically expanded beyond Northwest and Central India to include the East Coast, Peninsular, and Southern regions.
- The 2023 IPCC Synthesis Report warns that human-induced climate change will significantly increase extreme heat events, resulting in higher mortality and threatening food and water security.

Prelims Trap
"Heat waves are formally notified as a national disaster under the Disaster Management Act, 2005."
Despite severe impacts and NDMA guidelines, heat waves are currently NOT formally notified as a national disaster under the DM Act, 2005.
Static Concepts Connected
What are the IMD's criteria for declaring a heat wave?
- Plains threshold: The maximum temperature of a station must reach at least 40°C.
- Hilly regions: The maximum temperature of a station must reach at least 30°C.
- Temperature departure: The departure from normal temperature must be between 4.5°C to 6.4°C (Severe heat wave if > 6.4°C).
How does the Indian Constitution address environmental protection?
- Article 21: Judicial interpretation (e.g., M.K. Ranjitsinh case) includes the right to a clean environment and protection from adverse climate change effects under Right to Life.
- DPSP (Article 48A): Directs the State to endeavor to protect and improve the environment and to safeguard the forests and wildlife of the country.
- Article 51A(g): Makes it a duty of every citizen to protect and improve the natural environment, including forests, lakes, rivers, and wildlife.
Cross-Topic Patterns
Climate Jurisprudence & Executive Accountability
SC's use of Articles 14 and 21 to force implementation of NDMA guidelines highlights the growing intersection of fundamental rights, judicial activism, and disaster management.
Spatial shift & Urban Heat Islands
The expansion of heat waves to Peninsular India connects to unplanned urbanization, urban heat islands, and altering local microclimates that worsen the region's overall climate vulnerability.
