The role of heat, the authors said, may be just as significant as other, more well-known drivers of suicide, like economic hardship, which also pushes rates up, and suicide prevention programs and gun control legislation, which tends to push rates down.
SAN FRANCISCO – More people are likely to take their own lives at the planet warms, say researchers at Stanford University and the University of California at Berkeley in a study published
The multidisciplinary research team looked at nearly 1 million suicides in North America and found that hotter temperatures correlate with higher suicide rates. The warming projected through 2050, the group figures, could increase suicide rates by 1.4 percent in the US and 2.3 percent in Mexico over that time, resulting in 21,000 additional deaths in the two nations.

Burke and his colleagues, however, said that it is likely to have a positive effect on a person's well-being.
The researchers said that they have such a large number of suicides over such a long period of time – 866,000 in the US and 74,000 in Mexico as far back as 1968
"The only explanation is that it is some of the consequences of hot air temperatures," Burke said, noting that some of them have been slowed down, that they are more problematic. "
The study indicates that the link between heat and suicides was still discernible in warm and cold climates.
The results of a physiological factor suggest that people are truly driving a person's mental state.
"We wanted to be as sure as we were said Solomon Hsiang, co-author and badociate professor of public policy at UC Berkeley.
The researchers observed more than 600 million Twitter posts to evaluate moods in different types of weather. They found that every 1.8-degree Fahrenheit increase in temperature, or 1 degree Celsius, raises the likelihood of a depressive tweet, one that contains such words as "lonely" or "suicide," by as much as 1 percent.

"It looks very much like it's something that's mental and less contextual," he said. said.
The depressive tweets and suicide risk is one of the most common causes of death in the world.
the academic literature, you hear that there's going to be winners and losers, '' Burke said. "In suicide, that's not what we find at all. Everyone is losing. ''
Nationwide, 45,000 suicides occurred in 2016, making it one of the top 10 causes of death in the U.S., according to the Centers for Disease Control and Prevention. In California, suicides increased 14.8 percent between 1999 and 2016, according to the CDC

"There may be a relationship between climate change and suicide," he surmised, "but it might be simpler than that."
The new study on suicides is published in the journal Nature Climate Journal Change.
