In an article published at the end of March in Nature Medicine, a group of European and Canadian scientists practically beg their audience to believe that people are committing suicide because of climate change.
The scientists claim there are “empirically documented associations” between the “spectrum of suicidal behaviors” and “climate-related hazards.” (RELATED: The Real Climate Change Disaster)
They write that risk factors for suicidal behavior now include “climate anxiety, eco-anxiety and climate-related guilt.” These risks will increase as a result of climate change, they say.
While 5 percent of suicides today are a direct result of climate change, they assert, 7 percent of suicides will be caused by warming temperatures by 2035. They base that claim on a study in World Psychiatry.
Furthermore, they contend that a portion of this heightened suicide risk is simply due to the fact that hotter temperatures cause people to act more impulsively.
“Evidence from naturalistic and experimental studies,” the scientists write, “show a clear link between hotter ambient temperatures and impaired decision-making, as well as more impulsive and aggressive behaviors, which could lower the threshold for some suicidal acts.”
Curiously, the scientists also came up with a list of strange ways higher temperatures could create behavioral changes that lead to suicide: “Other potential mechanisms include mental health and behavioral changes due to heat-related sleep loss, alcohol-induced impulsivity, interactions with serotonin metabolism and altered effectiveness of certain psychotropic medications.”
The scientists also postulate that climate change will cause mental disorders, which will result in a greater number of suicides. They say: “Climate-related hazards will increase risks for both mental disorders and reduced psychological wellbeing.”
The scientists implore people to believe that climate change, here and now, is causing scores of people to kill themselves. “Climate change impacts are no longer theoretical,” they write, “they are visible now.”
The scientists include Francis Vergunst of the University of Oslo, Massimiliano Orri and Marie-Claude Geoffroy of McGill University, Massimiliano Orri of the Danish Research Institute for Suicide Prevention, and Alberto Forte of the University of Lausanne.
Nature Medicine is currently ranked as the top scientific journal in the category “Biochemistry & Molecular Biology.”
