Via Stephan Lewandowsky who writes:
Never before in recorded history has Australia experienced 5 consecutive days of national-average maximum temperatures above 39C. Until today.
And this heat is expected to continue for another 24-48 hours, extending the new record run to 6 or even 7 days.
For context, the previous record of 4 days occurred once only (1973) and 3 days has occurred only twice (1972,2002).
This information is from within the Bureau and reliable but it has not been released to the public yet–but feel free to spread.
I have enclosed a temperature map that may be of interest.
