What Happened
- Kenya recorded its seventh warmest year in 36 years during 2025, extending a long-term warming trend of approximately 0.22°C per decade since 1991.
- The Kenya Meteorological Department's annual report warns that 2026 will be hotter still, with above-average temperatures and uneven rainfall raising risks of heat stress, floods, and landslides.
- There is a 58–61% probability of El Niño conditions developing between June and December 2026, which would further disrupt weather patterns.
- Agricultural output suffered dramatically in 2025: maize and bean yields fell 21–35%, vegetable production dropped 39%, and maize stocks declined 37% — severely affecting food security.
- Four types of extreme weather were recorded in 2025: extreme heat (January–February), extreme cold (June–August), heavy rainfall events (March–May and October–December), and strong coastal winds.
- Climate-linked diseases including cholera and visceral leishmaniasis became more widespread; Kenya requires approximately KES 57.31 billion ($456.63 million) to address humanitarian needs through mid-2026.

Climate Change in Sub-Saharan Africa: Vulnerability and Impact
Sub-Saharan Africa is among the world's most climate-vulnerable regions, despite contributing relatively little to cumulative greenhouse gas emissions. The region faces a "climate paradox" — lowest historical emitter, highest per capita vulnerability. Kenya's experience is emblematic of broader African trends: rising temperatures, more variable rainfall, increased extreme events, and cascading impacts on agriculture, water, and health.
- IPCC Sixth Assessment Report (AR6, 2022): Africa is warming faster than the global average; temperatures have risen 0.3°C above the global mean warming since pre-industrial times.
- 1.5°C threshold: Even at this target, Sub-Saharan Africa faces disproportionate impacts — crop yield losses of up to 20% for key staples by mid-century.
- Loss and Damage: The COP27 (Sharm el-Sheikh, 2022) agreement to establish a Loss and Damage fund was a direct response to climate-vulnerable nations like those in Africa.
- Kenya's warming rate (0.22°C/decade) is consistent with broader East African trends driven by the Indian Ocean warming and changing monsoon patterns.
- 2024 and 2025 ranked among the warmest years in the 176-year global observational record.
Connection to this news: Kenya's climate data illustrates why developing nations insist on equity in climate negotiations — they bear costs disproportionate to their emissions, a core argument in UNFCCC/COP debates examined in UPSC.
El Niño-Southern Oscillation (ENSO) and Its Global Impacts
El Niño is a periodic warming of central and eastern Pacific Ocean surface temperatures that disrupts normal atmospheric circulation patterns, causing climate anomalies worldwide. Its counterpart, La Niña, involves cooler-than-average Pacific temperatures. ENSO is one of the most studied and UPSC-tested climate drivers.
- El Niño: Weakens the Walker Circulation; causes drought in Australia, southern Africa; excess rainfall in parts of South America and East Africa.
- La Niña: The opposite; typically brings heavy rainfall to Australia and South Asia.
- ENSO cycle: Typically 2–7 years; events last 9–12 months on average.
- Impact on India: El Niño years tend to suppress the Indian Summer Monsoon (ISM), affecting agricultural output; La Niña years often bring above-average monsoon.
- 2023–24 El Niño was one of the strongest on record; 2026 forecast of 58–61% probability signals a new developing event.
- WMO tracks ENSO and issues seasonal forecasts; the Kenya Meteorological Department relies on these forecasts for national planning.
Connection to this news: The forecast El Niño for June–December 2026 in East Africa is directly tied to Kenya's projected climate risks — providing a classic UPSC linkage between ENSO dynamics, regional climate impacts, and food/water security.
Food Security and Climate Nexus
Climate change is increasingly recognised as a threat multiplier for food security. Kenya's 2025 agricultural data — 21–35% yield drops for staple crops — illustrates how climate variability can rapidly erode food systems built around rain-fed agriculture. This is directly relevant to UPSC questions on food security, agricultural policy, and climate adaptation.
- Kenya's agriculture: Approximately 75% of Kenya's population depends on rain-fed agriculture; the sector contributes 26% of GDP and 65% of export earnings.
- Staple crops at risk: Maize (the primary food staple), beans, and vegetables are all rain-dependent and highly sensitive to temperature and rainfall variability.
- Food insecurity cascade: Lower yields → higher food prices → reduced dietary diversity → malnutrition → increased vulnerability to disease.
- Adaptation strategies: Climate-resilient seed varieties, irrigation expansion, weather-indexed crop insurance, food storage buffers, early warning systems.
- Global food system linkages: Kenya's food crisis reinforces the case for the African nations' demands at COP30 (Belem, 2025) for increased climate finance.
Connection to this news: The dramatic fall in Kenya's crop yields in 2025 demonstrates that climate change is no longer a future risk — it is present-tense food insecurity, affecting 75% of Kenya's population today.
