COP31 opens in Antalya; WMO puts 2026 among four warmest years
COP31, the UN's annual climate conference, opened in Antalya, Turkiye, on 9 November 2026. Turkiye presides, and Australia leads the negotiations. On the opening day, the World Meteorological Organization's State of the Climate Update 2026 put January–September warming at 1.47 °C above the 1850–1900 average. It found 2023–2026 to be the four warmest years on record.
Syllabus: Prelims · Environment & Ecology; GS3 · Environment & Conservation; GS3 · Disaster Management
Why this matters for UPSC
GS3 environment: the UNFCCC's Conference of the Parties, the Paris Agreement and the WMO's climate reports. Prelims can ask greenhouse gas trends and El Niño; Mains, climate finance and the implementation gap.
Why it matters
A farm worker in a rain-fed district, or a labourer on a city building site, lives with the gap between climate promises and climate action. When warming runs ahead, heatwaves grow fiercer, rain-fed harvests fail more often and the risk of diseases such as malaria and dengue shifts. Poorer countries need money to build sea walls, switch to drought-resistant crops and rebuild after disasters, and that money is where the talks keep stalling. If this conference turns earlier promises into funded plans, vulnerable countries get real help to adapt. If it does not, the bill falls on households that did the least to cause the warming.
Prelims pointers
- The Paris Agreement (2015) sets 1.5 °C above pre-industrial levels as its most ambitious temperature threshold; the WMO takes 1850–1900 as the pre-industrial baseline.
- Look-alikes: the State of the Global Climate is the WMO's report, built with inputs from National Meteorological and Hydrological Services; UNEP, a different UN body, publishes its own assessments.
- Mauna Loa in Hawaii and Kennaook/Cape Grim in Australia are benchmark stations that track atmospheric greenhouse gas concentrations.
- Since 1750, methane has risen about 167%, far more in proportion than carbon dioxide, and nitrous oxide 26% (WMO); both are given in ppb, carbon dioxide in ppm.
- El Niño typically raises annual global mean temperature by about 0.1–0.2 °C, with its greatest effect in the year after it develops; La Niña has a temporary cooling effect.
- Sea-level rise comes from melting glaciers and ice sheets and from the thermal expansion of warming sea water.
Practise a UPSC-style question
With reference to decisions on fossil fuels at UN climate conferences, consider the following statements:
1. The COP30 deal explicitly called on countries to phase out fossil fuels.
2. At COP28 in Dubai in 2023, countries committed to transition away from fossil fuels.
Which of the statements given above is/are correct?
- (a) 1 only
- (b) 2 only
- (c) Both 1 and 2
- (d) Neither 1 nor 2
Show the answer
Answer: (b) 2 only
Answer: (b) 2 only. The COP28 commitment stands; the COP30 deal left fossil fuels unnamed.
Statement 1: incorrect. Oil-producing countries blocked any reference to fossil fuels, so the COP30 deal left them unnamed; Brazil offered a voluntary roadmap instead.
Statement 2: correct. At COP28 in Dubai in 2023, countries pledged to transition away from fossil fuels, a commitment they have since struggled to put into practice.
Eliminate: statement 2 is correct, so (a) and (d) go. Out: (a), (d).
Eliminate: statement 1 is incorrect, so (c) goes. Out: (c).
Trap: Swapped attribution. The fossil-fuel commitment made at COP28 is pinned on COP30, whose deal did not name fossil fuels at all.
Remember: COP28 (Dubai, 2023) agreed to transition away from fossil fuels; COP30 left only a voluntary roadmap.
