Here in the United States, a vast high-pressure dome brought record heat to California and other western states over the Labor Day weekend. In Southern California, Burbank reached 110 degrees Fahrenheit on Monday, while in the north, Livermore hit a high of 116 degrees — 8 degrees higher than the previous record. Fresno’s forecast today calls for 114-degree heat, which would be an all-time temperature record for September. The intense heat has helped fuel wildfires, including the Mill Fire, which killed two people Sunday as it tore through the Northern California town of Weed.
