2026 to be one of four warmest years on record: World Meteorological Organization
The key reason behind the rising global temperatures is that the Earth’s energy imbalance is rising, and the earth system is accumulating heat at an accelerating rate, said WMO

Context
The (WMO) released its 'State of the Climate Report' at the beginning of the (COP31) in Antalya, Türkiye. The report projects that 2026 will be among the four warmest years on record, driven by record-high greenhouse gas concentrations and an intensifying event. The rising global average temperature, coupled with record ocean heat, is exacerbating extreme weather events globally, including severe heatwaves in India.
UPSC Perspectives
Environmental
The report highlights the accelerating energy imbalance of the Earth system, fundamentally driven by rising greenhouse gas concentrations. The data shows significant increases in carbon dioxide and methane levels compared to pre-industrial times, which trap outgoing terrestrial radiation. This leads to the greenhouse effect, causing global warming. A critical environmental concern raised is the ocean's role as a heat sink; absorbing 90% of excess heat leads to ocean thermal expansion (contributing to sea-level rise) and widespread marine heatwaves, which devastate coral reefs and marine ecosystems. For UPSC Mains, candidates should be able to link rising GHG concentrations to specific impacts like ocean acidification and shifting climatic zones, highlighting the urgent need for mitigation strategies as discussed at international forums like the .
Geographical
The report underscores the profound impact of climate variability phenomena, particularly . is characterized by the unusual warming of surface waters in the eastern tropical Pacific Ocean, which disrupts normal atmospheric circulation patterns like the Walker Circulation. The report notes this current is intensifying and expected to be exceptionally strong, releasing massive amounts of oceanic heat into the atmosphere and fueling global temperature rises. From a geographical perspective, significantly alters global weather patterns, often leading to droughts in Australia and parts of Asia (including weakening the Indian Monsoon) and increased rainfall in parts of the Americas. Understanding the mechanics of (ENSO) and its teleconnections (how phenomena in one area affect distant areas) is a core requirement for GS Paper 1.
Governance
The findings present significant challenges for global and national governance, particularly concerning climate justice and disaster management. The emphasized that those least responsible for climate change are suffering the most, underscoring the principle of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC). The report highlights specific human impacts, such as the massive exposure of India's population to extreme heat. This necessitates robust national governance frameworks focused on climate adaptation, such as the (NAPCC) in India. Effective governance requires implementing heat action plans, building resilient infrastructure, and addressing the socio-economic vulnerabilities (like poverty and food insecurity) exacerbated by extreme weather events. The demand for accelerated emissions cuts and increased climate finance highlights the critical role of multilateral negotiations in global climate governance.
