Back in Hansen’s safe days of CO2 far below 350 ppm, Death Valley had seven days in a row with temperatures over 127F. This included July 10 which hit 134F – the hottest temperature ever recorded in North America.
At the time, 134 was the hottest temperature ever recorded on the planet. But nine years later, Libya hit 136 degrees.
Unlike many modern sites, the Death Valley station was properly sited with no asphalt, buildings or air conditioners.
