Unseasonably Warm Weather Drives Record-High Temperatures Across the U.S.

Unseasonably warm weather has gripped much of the United States, pushing temperatures to record highs and raising alarms among climate scientists and communities alike. From the Midwest to the Northeast, thermometers have climbed well above seasonal norms, with some regions experiencing their warmest fall on record. In Duluth, Minnesota, for instance, this fall was the second-warmest ever documented, with an average September-through-November temperature of 49.7 degrees—just a tenth of a degree shy of the all-time record. Such anomalies are no longer isolated incidents but part of a broader, troubling pattern.

The implications of these rising temperatures extend far beyond discomfort. As one expert notes, “Whether 2026 ultimately ranks as number one or number three doesn’t distract from the bigger story that temperatures are rising across the country and leading to major impacts for communities.” Even if the year doesn’t set a new global record, the nation remains at high risk of “fossil-fueled extremes” such as heat waves and extraordinary rainfall. These events threaten lives, livelihoods, and infrastructure. The year has already seen its share of disasters: the Thompson Fire in California forced over 13,000 people to evacuate in early July, while Hurricane Beryl made landfall in Texas days later, causing significant damage, power outages, and eight fatalities. Alaska, too, experienced unusual precipitation patterns, with January–July precipitation ranking in the wettest third of the 100-year record, and below-average precipitation in parts of the Cook Inlet, Aleutians, and South Panhandle regions.

Scientists and advocates stress that these extremes are not random. “Temperatures to know that fossil-fueled climate change is threatening our economy, our critical infrastructure, our health and our national security,” one expert warns. The convergence of heat, drought, and flooding is straining resources and highlighting the urgent need for climate action.
