How the exam will ask it
Prelims
- The UN General Assembly adopted its first declaration on sea-level rise at its 81st session in New York.
- Saltwater intrusion, coastal flooding and erosion are among the main threats of sea-level rise to coastal and island States.
- UNGA declarations are generally not legally binding treaties; they carry political and normative weight.
Mains
GS-III Environment and GS-II International Organisations. Issue: sea-level rise endangers low-lying island States and coastal populations through erosion, flooding and saltwater intrusion; the UNGA declaration is a political commitment rather than a binding treaty. Implication: India's long coastline is exposed to coastal erosion, so the way forward lies in coastal adaptation, ecosystem protection and active climate diplomacy for vulnerable States.

Show answer
Answer: C — Correct: 81st session — The declaration was adopted on 24 September 2026 at a high-level meeting during the 81st session in New York. • 79th session — wrong: The 79th session ran a year earlier than the one in which this declaration was adopted. • 80th session — wrong: The 80th session preceded the current one, so it is not the session of this adoption. • 82nd session — wrong: The 82nd session has not yet begun, so nothing could have been adopted in it.
