Another heat record has tumbled as Australia's year long heat wave continues. Australia has (again) broken the record for warmest 12 months on record after previously breaking it only last month.
The heat in September was something else, at +2.75 °C above the long-term (1961–1990) September average. Naturally this was the warmest Sept on record, what's more amazing is that in the last hundreds years of temperature records, no month has ever been more above the long term average. On in meteorology speak Sept 2013 "sets a record for Australia’s largest positive anomaly for any monthly mean temperature."
