Overview
The World Meteorological Organization (WMO) said that the global average temperature for January‑September 2026 was **1.47 °C** above the pre‑industrial baseline. This makes 2026 one of the four warmest years on record and only slightly cooler than the warmest year, 2024.
Key Developments
- WMO released the State of the Climate Report on the opening day of COP31 in Antalya, Turkey.
- The ongoing El Niño is projected to become the strongest on record by December, further raising temperatures into 2027.
- Atmospheric carbon dioxide rose to **426.8 ppm** in 2025, a **53 %** increase since 1750.
- Methane levels reached **1,948 ppb**, a **167 %** rise from 1750.
- Oceans have absorbed **90 %** of excess heat, marking the tenth consecutive year of record ocean warmth.
- Extreme events caused over **30,000 excess deaths** in Europe and exposed **146.5 million Indians** to extreme heat in April 2026.
Important Facts
The WMO report attributes the temperature rise to a growing greenhouse‑gas induced energy imbalance. The imbalance is now at its highest level since systematic monitoring began, meaning more solar energy is retained than emitted.
Heat in the oceans has broken records for ten straight years, amplifying the intensity of heatwaves, droughts, and wildfires worldwide.
Exam Relevance
Understanding these trends is crucial for GS III (Environment & Ecology) and GS II (International Relations). The data illustrate:
- How global climate indicators are measured and reported.
- The role of international forums like COP31 in shaping climate policy.
- The socio‑economic impact of climate extremes on health, agriculture, and migration, linking to GS III and GS IV (Security).
- India’s vulnerability, highlighted by the 146.5 million people exposed to extreme heat, which is relevant for questions on disaster management and sustainable development.
Way Forward
To curb further warming, the UN Secretary‑General urges:
- Accelerated reduction of CO₂ and other greenhouse‑gas emissions.
- Rapid transition to renewable energy and a just shift away from fossil fuels.
- Enhanced climate finance for vulnerable nations, especially for heat‑wave preparedness and adaptation.
For UPSC candidates, focus on the link between scientific data (temperature anomalies, gas concentrations) and policy responses (international negotiations, national adaptation strategies). Mastering these connections will aid answers in both descriptive and analytical questions.
