“Determining whether or not the rate of suicide responds to climatic conditions is important, as suicide alone causes more deaths globally than all forms of violence combined and is among the top 10–15 causes of death globally,” said Prof Marshall Burke, at Stanford University in the US, and his colleagues, who published their research in the journal Nature Climate Change.
“Even modest changes in suicide rates due to climate change could [lead to] large changes in the associated global health burden, particularly in wealthier countries where current suicide rates are relatively high,” the researchers said. Record high temperatures have been recorded around the world in recent weeks and are likely to have been driven by climate change.
This kind of study cannot prove a causal link between rising temperature and more suicides. But the results show “remarkable consistency” over time and in many different places, according to the scientists. It is also supported by recent research that linked climate change to 60,000 suicides in India in the last three decades.
