Heat-related deaths under-estimated as temperatures and extreme heat events increase

Moreland’s social heat vulnerability

Researchers at the Australian National University say that heat related deaths have been greatly underestimated. In the 11 years between January 2006 and October 2017 an estimated 36,765 deaths in Australia can be attributed to heat-related causes.

As we know climate change is increasing average temperatures and the frequency and intensity of extreme heat events in Australia.

Summer time and heatwave management shows some cracks

SE Australian Heatwave

SE Australian Heatwave

Melbourne sweltered through another heatwave, the first of 2017. Hope everyone survived the heat.

Temperature at Melbourne (Olympic Park) hit 36.1C at 3.30pm on Saturday. Of far greater concern, the overnight minimum temperature hovered at around 30C dipping down to 28.4C at 1.30am as the low point before rising to 30C at 9am Sunday. By early afternoon a cool change had moved through dropping temperatures to the mid 20s.

High night time temperatures disturb sleep and reduce physiological recovery for the next day. Night time is also when the Urban Heat Island effect is most pronounced as there is less atmospheric mixing, and zero vegetation transpiration to cool things down, unless there are stronger winds. The Bureau of Meteorology labelled the night as ‘oppressive’ citing both the higher than normal minimum temperature and higher humidity.
