What were the global temperature records set in 2026 and how does El Niño contribute?
August 2026 was the hottest month ever recorded globally, averaging 62.53 degrees Fahrenheit and edging out July 2023 by just a hundredth of a degree Celsius. El Niño is contributing roughly 0.1 to 0.2 degrees Celsius to these record temperatures, but scientists say the real culprit is decades of accumulated greenhouse gas emissions.
The scale of this heat event extends beyond a single month. The U.S. summer of 2026 (June through August) averaged 74.37 degrees Fahrenheit, marking the hottest summer since the Dust Bowl era of 1936—a 90-year benchmark. Across the United States alone, climate stations set or tied 1,541 monthly record highs during that summer, a staggering concentration of extreme heat events in a single season.
What makes this even more concerning is what scientists are predicting next. There is a greater than 90% probability that 2027 will be even hotter than 2026, suggesting this isn't a one-year anomaly but part of a larger warming trajectory. As Neal Freyman discusses in the episode, the data paints a picture of a climate system pushed to the brink by long-term human activity.
El Niño's Role—Large But Not the Main Story
El Niño, the periodic warming of the equatorial Pacific Ocean, is often blamed for extreme weather events. While it is genuinely adding heat to the global system—between 0.1 and 0.2 degrees Celsius—it is not the dominant driver of these record temperatures. Think of El Niño as a significant but temporary accelerant on a fire that greenhouse gases have been building for decades.
The distinction matters because it clarifies the urgency of the problem. The Morning Brew Daily episode explores how climate scientists distinguish between short-term natural cycles and long-term structural warming. El Niño will eventually fade—it always does—but the greenhouse gas warming will persist and intensify unless emissions decline significantly.
Key takeaways
- August 2026 holds the record for hottest month ever recorded globally at 62.53°F, barely surpassing July 2023.
- The U.S. summer of 2026 was the hottest since 1936, with 1,541 record highs set or tied across the country.
- El Niño contributes 0.1–0.2°C to current temperatures, but decades of greenhouse gas emissions are the primary driver.
- Scientists forecast a greater than 90% probability that 2027 will be even hotter than 2026.
