Global Heat and Food Prices Surge as September Sets New Climate Records

September was the second hottest on record globally, with temperatures reaching 1.63°C above pre-industrial levels, according to the Copernicus Climate Change Service. This marks the second consecutive month that global temperatures have exceeded the 1.5°C threshold, a sequence that began in August and is expected to continue through 2027, as reported by sol.iol.pt. Western Europe experienced record average temperatures during the month, while oceans outside the polar regions also saw their highest temperatures ever recorded for September, according to Diário de Viseu. The warming trend is being amplified by an El Niño event that is "caminha para um dos mais fortes de que há registo" (heading toward one of the strongest on record), as publico.pt reported. "Pelo segundo mês seguido, a temperatura global ficou acima de 1,5°C em relação ao período pré-industrial." This sustained breach of the 1.5°C mark, a key threshold in the Paris Agreement, underscores how quickly the climate system is shifting, even if the long-term average has not yet crossed that line. The heat is having direct economic consequences. Global food prices rose 5.8% in September, with the main causes linked to disruptions in the Strait of Hormuz and the Black Sea, as well as climate impacts, according to Correio da Manhã. These shipping chokepoints are critical for grain and energy exports, and their instability is feeding into higher costs for consumers worldwide. "Principais causas estão relacionadas com interrupções no estreito de Ormuz e no Mar Negro, assim como o impacto climático." The combination of record ocean temperatures and geopolitical tensions in key trade routes is creating a dual pressure on food systems, sabado.pt noted that average temperatures also broke records in western Europe, tying the climate and economic threads together. With the El Niño expected to persist, the coming months may bring further temperature records and continued volatility in food markets, as the Copernicus data suggests the streak of months above 1.5°C will extend into the near future.
