South Australia: number of days over 35C in the state will more than double in six decades

According to science reporter Clare Peddie, deadly heatwaves will become twice as common in South Austrtalia by 2070, according to a comprehensive climate report that predicts higher temperatures will threaten water supplies, infrastructure and lives, The Advertiser (3/10/2007, p.1)

CSIRO, BOM assessment: A landmark joint assessment by the nation’s peak scientific bodies, the CSIRO and the Bureau of Meteorology, has revealed that the number of days over 35C in this state will more than double in six decades if global warming is not curbed. Scientists predict that an in­crease in the number of over-35C days from the average now of 17 a year to 47 will dry up water supplies, buckle infra­structure and cost lives among the elderly.

Big impact: CSIRO principal research scientist Kevin Hennessy said bureau data on daily tempera­tures had been combined with CSIRO modelling to reveal the “striking” results. “A small change in average temperature will have a large effect on extreme tempera­tures,” he said. “We expect fewer frosts and more heatwaves. In Adelaide there are cur­rently 17 days per year over 35 degrees on average, this could increase to between 21 and 26 days by the year 2030 and 24 to 47 days by the year 2070.”
