Industry Odisha Bureau, Oct 01: Researchers have linked food-price spikes from 2022 to 2026 with extreme weather. Damaged harvests are lifting staple costs. A severe El Niño could extend that pressure into 2027.
Weather shocks once lifted food prices briefly before fading away. New research suggests climate change is making that pressure more persistent. The study comes from Zero Carbon Analytics, an international research firm. Its findings show how a damaged harvest can make a grocery item more expensive.
Tracing the Price Spikes
The analysts mapped food-price spikes between 2022 and 2026. They traced these to extreme weather events they link to climate change. This year, all but one documented spike involved unprecedented temperatures, drought or rainfall. Those events exceeded anything comparable in the historical climate record. The researchers used a method developed by the Barcelona Supercomputing Center and European Central Bank.
The exception matters. A winter storm pushed US tomato prices up about 40%. Yet that storm was not made worse by climate change. It is a reminder that extreme weather and climate attribution are not the same.
From Harvest to Household
The economic chain is fairly direct. Extreme weather damages crops and weakens yields. Tighter supply then lifts commodity prices, which can reach supermarket shelves.
Some economists call this effect “climateflation”. Joanne Bentley-McKune, a climate scientist, led the Zero Carbon Analytics briefing. She described climateflation as a permanent rise in everyday living costs. She linked it to fossil-fuel dependency and destruction from extreme weather.
Yet climate is not the only force at work. In 2026, geopolitical tensions disrupted trade corridors in the Middle East and Black Sea. That pushed agricultural input costs sharply higher.
Staples Under Strain
Wheat, corn, cocoa and sugar prices have all risen this year. Those gains helped lift the United Nations food-commodity index. In August, it reached an almost four-year high.
Europe’s Scorching Summer
Europe offered a clear example of production risk. Parts of the continent endured their hottest summer on record. Temperatures topped 44°C in southwest France. The UK recorded its hottest June day in history.
World Weather Attribution examined the soil drought behind much of the crop damage. Human-caused climate change made it about five times more likely in western Europe. In eastern Europe, it became 11 times more likely.
France, the EU’s largest agricultural producer, suffered heavy farm losses. Corn was among the hardest-hit crops. The country now faces a sharply reduced corn harvest.
No Shelter in Self-Sufficiency
The report warns that food self-sufficiency may offer limited protection. Local yields can still fail under extreme weather. Global production shocks can also move international market prices. Even countries growing their own staples could face inflation, the authors said.
A Risk Stretching Into 2027
The pressure may not ease soon. A historically severe “super” El Niño could threaten global food supplies into 2027. Extreme weather has already begun to threaten next year’s planting window.
Weather as an Economic Force
Weather is becoming a more lasting driver of food costs. Yet attribution remains event-specific, as the tomato case shows. Not every price spike carries a climate fingerprint. But where links exist, the research shows the cost can reach household budgets.
