New Study: Australians Were 600% More Likely To Die From Cold Than Heat During 2000-2009

According to a comprehensive (305 locations in 10 countries) 2018 study, deaths attributed to extreme heat have been stable to declining in recent decades (1985-2012).  In contrast, deaths attributed to cold weather show “no clear patterns” – neither increasing or decreasing.

Across the globe, recent cold spells have become more and more deadly.

In the UK, for example, there were 50,100 excess deaths due to a prolonged spell of extreme coldduring the winter of 2018, which is the highest mortality number since 1976 for this region.  In contrast, deaths associated with summer heat waves usually only reach into the hundreds or less.

Despite Australia’s relatively warm climate, there were about 6 times more attributable cold-related deaths (61.4%) than heat-related deaths (10.6%) during the first decade of the 21st century.

In Southwest China, like Australia, there were 6 times more deaths attributable to cold weather (4.08%) than to hot weather (0.67%) during the 2009-2016 period, when global temperatures were often said to be “the hottest on record”.

Even for warm-weather India, moderately and extremely cold temperatures had an attributable mortality risk many times greater than moderately and extremely hot temperatures during 2001-2013.

In Spain, the frequency of cold days increased slightly during 1983-2013.  While heat-related deaths decreased in frequency during this time span, cold-related mortality has been increasing.

The authors (Díaz et al., 2019) suggest that increased energy poverty and the high costs to heat homes are a significant reason why cold-attributable deaths have risen in Spain.

Considering the death toll for cold weather events hasn’t been declining in recent decades, and that cold weather is far more deadly than hot weather, perhaps there should be more of an emphasis on policies and practices that keep citizens safe during cold weather events in this “global warming” era.

    In the coming decades it is clear that the coming change to a global cool phase will kill many more worldwide. With governments just about everywhere willfully ensuring that assistance and relief will be late in starting, if it come at all.
