Heat wave sweeps the United States
Earth’s average temperature on Wednesday remained at an unofficial record high set the day before, the latest grim milestone in a week that has seen series of climate-change-driven extremes. The average global temperature was 17.18 Celsius (62.9 degrees Fahrenheit), according to the University of Maine’s Climate Reanalyzer, a tool that uses satellite data and computer simulations to measure the world’s condition. That matched a record set Tuesday, and came after a previous record of 17.01 Celsius (62.6 degrees Fahrenheit) was set Monday.
