UPDATE: Australia suffers through record-hot March



March was Australia's hottest on record, with temperatures 2C above average.  (The Guardian, 4/2/2019)
The latest monthly climate breakdown shows that despite two severe tropical cyclones in the northern states, temperatures across Australia were 2.13C above the average throughout last month in part due to an unusually dry summer in Western Australia and the Northern Territory. 
“One of the standout features of March was there was above-average temperatures just about everywhere; more than 99% of the country,” Blair Trewin, a senior climatologist at the bureau told Guardian Australia.

Australia shatters record for its hottest summer.  (Axios, 3/1/2019)
Australia is one of the countries most impacted by climate extremes, suffering from heat waves, bushfires and coral bleaching events tied to long-term, human-driven increases in greenhouse gas concentrations. However, this summer brought unprecedented heat to every part of the country — part of a trend consistent with what scientists predict as global warming continues.
Other notable records:
  • highest mean maximum temperature
  • highest mean minimum temperature
  • 3.8 degrees Fahrenheit above 1961-90 average
The long run of hot, dry weather has taken a heavy toll on the nation’s £3.2 billion wine industry, which has become renowned for varieties such as shiraz, chardonnay and cabernet sauvignon. 
Australia is the world’s sixth largest wine exporter, including large supplies to China, the United States and the UK. But the searing heat has caused grapes to ripen more quickly, leaving growers struggling to pick them before they become sunburnt and shrivelled.

Poor building shells (roof, floor, walls, windows and doors) which let heat in, and hot direct sunlight through windows, particularly those that face west, are the main problems with most houses. Insufficient ceiling insulation, draughty windows and doors, and lack of glazed windows or external shading devices all contribute to low star energy ratings.
