Human-induced global heating ‘causes over a third of
heat deaths’
More than a third of all heat-related deaths around the world
between 1991 and 2018 can be attributed to human-induced global
heating, research has found.
Climate breakdown has a range of effects ranging from
wildfires to extreme weather. As the temperatures rise, more
intense and frequent heatwaves disproportionately affect elderly
people and those with underlying chronic conditions such as
asthma, making them more vulnerable to disease and premature
death.
A study, published in the journal Nature Climate Change,
used data from 732 locations in 43 countries to calculate the
number of deaths attributed to heat levels higher than the ideal
temperature for human health, which varies across locations.
The researchers examined past weather conditions simulated
under scenarios with and without emissions triggered by human
activity – allowing them to separate the warming and related
health impact linked with human activity from natural trends.
Overall, they found 37% of all heat-related deaths in the
locations studied were attributable to human activity – but the
largest climate change-induced contributions (more than 50%)
were in southern and western Asia (Iran and Kuwait), south-east
Asia (the Philippines and Thailand) and Central and South
America.
