In Australia fa così caldo che i metereologi hanno dovuto aggiornare la scala delle temperature aggiungendo un nuovo massimo, da 52° a 54°.
The bureau's head of climate monitoring and prediction David Jones said the new scale, which also features a pink code for temperatures from 52 to 54 degrees, reflected the potential for old heat records to be smashed.
"The scale has just been increased today and I would anticipate it is because the forecast coming from the bureau's model is showing temperatures in excess of 50 degrees," Jones told Fairfax newspapers.
Australia's all-time record temperature is 50.7 degrees, set in January 1960 at Oodnadatta in the state of South Australia.
The nation as a whole experienced its hottest day on record on Monday with the average maximum temperature across the country hitting 40.33 degrees, surpassing the previous mark of 40.17 degrees set in 1972.
