Record-Breaking Global Wildfire Season in 2026 Fueled by Climate Change and El Niño
5/13/2026, 6:54:04 AM
Record-Breaking Fire Start
From January to April 2026, over 150 million hectares (? 579 000 sq mi) burned—20 % above the previous record and roughly twice the size of Texas—straining crews in Argentina, Chile, Japan, the US and SE Asia.
Climate Drivers
Human-induced warming has dried vegetation, while a projected strong El Niño—warm Pacific sea-surface temperatures—could amplify heat and drought. In West Africa, rapid shifts from heavy rain to extreme dryness, termed hydroclimate whiplash, have created abundant dry fuel. WMO estimates a 61 % chance of El Niño by July.
Burned Area Statistics
- Africa: 85 million ha (23 % above 69 million ha record).
- Asia: 44 million ha (? 40 % above 2014).
- Global average: 50 % above typical for period.
- Other regions: US, Australia, Canada and the Amazon report unusually high burn extents.
Health, Economic and Environmental Impacts
Mahmood warns wildfire smoke contains PM2.5 up to ten times more harmful than traffic emissions, raising acute respiratory risk. The Lancet links 1.5 million annual deaths to air-pollution, likely to rise as fires increase. Heat-driven drought threatens crops and global food supply chains, and rising cooling demand could strain energy systems already stressed by the Iran war.
Scientific and Institutional Responses
Imperial College London’s Theodore Keeping and Friederike Otto of World Weather Attribution say the rapid fire start plus projected El Niño makes 2026 “particularly severe.” WMO warns El Niño may cause drought in Australia, Indonesia and South Asia. WWA’s review of over 100 extreme-weather events finds human-induced climate change now outweighs natural variability in driving such extremes.
Policy Critique
Mahmood notes governments have “stepped back from climate commitments,” treating the crisis as peripheral and behaving “as though the climate crisis was a chapter,” risking further heating without emission cuts.
Frontline Challenges
Firefighters in Argentina, Chile and Japan face shortages as multiple fronts burn, overwhelming resources; US crews battle record blazes in California and the Southwest, stretching response capacity.
Data Discrepancies
One source reports 1.63 billion ha burned, more than ten times the 150 million ha figure used elsewhere. Keeping’s affiliation varies between Imperial and King’s College London, indicating inconsistent attribution.
Verbatim Quotes
- “Whilst in many parts of the world the global fire season has yet to heat up, this rapid start, in combination with the forecast El Nino, means that we're looking at a particularly severe year materialising,” — Theodore Keeping, wildfire expert, Imperial College London
- “If there is a strong El Nino later this year, there is a serious risk that the effect of climate change and El Nino ... will result in unprecedented weather extremes,” — Friederike Otto, climate scientist, Imperial College London
- “5) from fire smoke could be 10 times more harmful to health than that from traffic emissions.” — Jemilah Mahmood, executive director, Sunway Center for Planetary Health
- “Human-induced climate change overtook the signal,” — Friederike Otto, WWA co-founder
Outlook
Forecasts see a strong El Niño heightening heatwaves, drought and fire risk across Australia, the US, Canada and the Amazon later in 2026; rapid cuts are urged.
