Another “Inconvenient Truth” –
“The world record for the longest sequence of days above 100°Fahrenheit (or 37.8° on the Celsius scale) is held by Marble Bar in the inland Pilbara district of Western Australia. The temperature, measured under standard exposure conditions, reached or exceeded the century mark every day from 31 October 1923 to 7 April 1924, a total of 160 days. ”
