Study Projects Spike In Heat-Related Deaths Among Elderly Melbourne Residents As Century Progresses

[hatrack]

THE number of elderly Melburnians dying due to extreme heat is expected to rise dramatically as climate change takes hold this century, research suggests. Heat stress is also projected to hit workplaces, with more regular oppressive days affecting productivity. A separate study found the projected increase in bushfires would reduce air quality, leading to more cases of potentially fatal respiratory illness.

Nicole Joffe from consultants Net Balance found the number of days with an average temperature above 30 degrees would double by mid-century - from two to at least four a year - even if governments acted to cut greenhouse emissions. Failure to tackle climate change would trigger a steeper rise.

In the past, extreme heat in this range has increased deaths among Melburnians aged 65 and older by nearly a fifth.

Ms Joffe said her results posed questions about how people adapt to climate change. "We need to look at air-conditioning and evaporative cooling as a start, but we also need policymakers to drive innovation in the area so we can find other solutions," she said from the Greenhouse 2009 conference in Perth.
