Claim: Global warming to cause more suicides

From the “P-hacking gets you any claim” and the “that’s why people move to Florida” departments.

By Mike Bastasch

A July study claims that thousands of more people will commit suicide in the coming decades due to man-made global warming.

Published in the journal Nature Climate Change on Monday, the study found a one-degree increase in average monthly temperature correlated with suicide rate increases of 0.68 percent and 2.1 percent in the U.S. and Mexico, respectively.

The effect they found is extremely small, and in some cases, not statistically significant from zero. Still, the results were touted in media reports as evidence that increased temperatures exacerbate suicides.

The study predicts between 9,000 and 40,000 more people will off themselves by 2050 because of man-made warming — based on an extreme warming scenario that experts increasingly call “exceptionally unlikely.”

“So we take a specific location and we take a specific month, and we compare cooler versions of that month to hotter versions of that month, and we ask, ‘Are suicide rates different during those two months?’ We indeed find that they are,” lead author Marshall Burke told CNN.

“We find a very consistent relationship between temperature increases and increases in suicide risk,” said Burke, an assistant professor at Stanford University.

A lot of research has been done into suicide rates and temperature. A recent British study found that heat waves exacerbated existing mental health problems in individuals, including suicide.

But Burke’s study only looked at average monthly temperature, which does not give an indication of heat waves or other phenomena that could exacerbate suicides. Higher average temperatures in any given month could be from warmer nights, rather than scorching daytime temperatures.

Cato Institute atmospheric scientist Ryan Maue noted that correlations with monthly temperatures aren’t reliable. Maue also criticized the study’s dependence on Twitter postings to gauge “depressive” speech.

P-hacking refers to the reanalyzing of data until a statistically significant result is achieved. It’s become a major concern in recent years among scientists who fear the practice is damaging their credibility and leading to the hyping of bad science.

Burke’s study averaged monthly temperature correlations across the U.S., which also obscured negative relationships between suicides and temperature increases. Nevada and South Carolina, for example, saw decreases in suicide rates as temperatures increased, but those decreases are obscured in the national average.

The study also claims that temperature increases correlated with a less than one percent increase in “depressive” language on Twitter. However, those results were only significant in one coding, which then had to be adjusted for “lagged effect.”

Hmmmmm. Each day starts off cool and warms up into the afternoon. Today started at 62F (7am) and it’s up to 87F right now. And yet I feel not the least urge to commit suicide on this fine summer day. Several cold adult beverages may meet their demise soon, however…..

It may even drive them to use more depressing language on Twatter.

The real quote is:

i.e. Correlates… and then projects…

But it does beg the question, how did they assess “suicide risk” ?

What is more dubious is the idea of “averaging” correlations. How does the maths behind that work? How does that affect the significance of the average of the correlation?

I wonder if they compared their study for predicted suicide rates when it gets colder.

Y’know, just for a balanced view.

Might include windier, wetter and, of course, full moon.

How about suicide rates vs. population density? Like how many pour souls can you jam into an urban heat island without adequate systems to handle the “population load” without expecting death rates from all sorts to rise. It’s not that the climate is any more extreme its that the infrastructure is operating at threshold or beyond. This is not a climate issue it is poor urban planning issue.

July 23, 2018 5:16 pm

“THE study also took into account seasonal variation, levels of poverty, the news of celebrity suicides and even depressive social media commentary that can lead to more death…

WHAT level of responsibility is the mainstream media itself willing to accept for stoking “global warming” fears – flogging every heatwave or extreme weather event leading to the collective mass hysteria played out on social media?”

Sound like a bit of hype about about SAD (link) to me.

Seasonal affective disorder (SAD) is a mood disorder subset in which people who have normal mental health throughout most of the year exhibit depressive symptoms at the same time each year, most commonly in the winter.[1][2] People may sleep too much or have little energy.[3] The condition in the summer can include heightened anxiety.[4]

In the Diagnostic and Statistical Manual of Mental Disorders DSM-IV and DSM-5, its status was changed. It is no longer classified as a unique mood disorder but is now a specifier, called “with seasonal pattern”, for recurrent major depressive disorder that occurs at a specific time of the year and fully remits otherwise.[5] Although experts were initially skeptical, this condition is now recognized as a common disorder.[6]

July 23, 2018 6:05 pm

If someone who is already depressed, knows none of the details about AGW and is continually bombarded with gloom and doom predictions like this, it just might increase their depression. Then they are now told that politicians like the “evil” Trump plan to do nothing to stop the “obvious” coming catastrophe, it just might increase the risk of the person doing something. Problem is it might not be suicide.

July 23, 2018 6:11 pm

The line of attributing suicides to global warming is false and unseamly, yet again exploiting a real concern to promote CO2 obsession.
1. A suicide is a personal event with many contributing factors, weather and climate being the most peripheral.

2. Serious suicide researchers have identified risk factors that inform caregivers, no mention of climate.

3. Suicides occur more frequently in colder climates than in warmer ones.

4. Preventing suicides is a serious issue, and has nothing to do with reducing CO2.

OK, once more — this time with feeling– “Correlation does not prove causation!”

However, inasmuch as the Arctic is warming about 2X the global average, I think that we should be on the look out for an increase in polar bear suicides.

I think that I could make a case for correlation between increasing temperatures and logic impairment in academics.

I suggest the quote merits capitals. And in bold. Correlation between figures is worth noting in case it leads anywhere but it isn’t worth the ink, or the electricity, for a published study.

eyesonu : WELL , historically speaking , HARRY HOUDINI for one !
The Belle Isle Bridge jump
On Tuesday, November 27, 1906, Houdini leapt manacled from the Belle Isle Bridge in Detroit, MI, freeing himself from two pairs of handcuff beneath the cold waters. The Belle Isle Bridge jump is one of Houdini’s most well-known, largely because of a fiction created about the escape. In later accounts, it was claimed that the Detroit river was frozen and a hole had to be cut in the ice. This provided Houdini with an additional horrifying dilemma when he found himself trapped under the ice. This dramatic version appeared in the first major Houdini biography, Houdini His Life Story by Harold Kellock, and passed as fact for many years.”

Suicide is highly complex. As someone that lost a close relative to suicide, I will state that suicide(like alcoholism, drug addiction, etc.) is “nature” not environment. For at least the last 10 years of his life, I think he had this abnormal compulsive feedback loop of self destruction. The fact that local temperatures varied from -25F to 100F+ during his life had nothing to do with it.

It seems obvious that a single hot summer doesn’t create suicidal people, let alone a global average increase of 0.6C over 50 years.

Suicide is a personal thing that develops over a period of years, having almost nothing to do with any reality outside of the persons head. This statement of mine is based on my own experience with depression and suicide.

Doomsday propaganda demoralizes people. It’s harder on souls who are already unhappy.

July 24, 2018 1:33 am

The Abstract of the paper reads:

Linkages between climate and mental health are often theorized but remain poorly quantified. In particular, it is unknown whether the rate of suicide, a leading cause of death globally, is systematically affected by climatic conditions. Using comprehensive data from multiple decades for both the United States and Mexico, we find that suicide rates rise 0.7% in US counties and 2.1% in Mexican municipalities for a 1 °C increase in monthly average temperature. This effect is similar in hotter versus cooler regions and has not diminished over time, indicating limited historical adaptation. Analysis of depressive language in > 600 million social media updates further suggests that mental well-being deteriorates during warmer periods. We project that unmitigated climate change (RCP8.5) could result in a combined 9–40 thousand additional suicides (95% confidence interval) across the United States and Mexico by 2050, representing a change in suicide rates comparable to the estimated impact of economic recessions, suicide prevention programmes or gun restriction laws.
[end of Abstract]

So the article alleges 9000 to 40,000 additional suicides in the USA and Mexico in the 32 years between now and 2050, or at most a ~1000 per year in the USA?

Lets compare that to the ~100,000 Excess Winter Deaths that occur in the USA EVERY year. That’s two 9-11’s per week for 17 weeks EVERY YEAR.

There is only one conclusion: Warmer is better, so Nuke any organization that opposes global warming.

It looks like they calculated the “additional suicides” incorrectly. Instead of using the ‘average’ rise on the total population, they should have used the country rates for the two countries and then added the estimated increases. It looks like they used some ‘mathemagic’ to inflate the numbers.

It is statistical malfeasance to leverage a minuscule value presently lost in noise or uncertainty into a very large population… for the express purpose of creating a hypothetical integer number of ‘deaths’. To which may be applied another form of journalistic malfeasance, such as taking the hypothetical people-count and statistically concluding that one will be a baby, so the piece can be illustrated with a stock photo of, a baby.

This is actually a good example of model selection bias. By leaving out opioids from the model, they are ignoring a major new demographic and public health hazard as though it does not exist.

My experience is, er, my climate model demonstrates people drink more booze in cold weather, since they’re cooped up inside, and bored.

“They discovered that for every 1-degree Celsius (1.8-degree Fahrenheit) rise in temperature, there was a 0.7 percent increase in suicide rates in the U.S. and a 2.1 percent increase in Mexico, averaging a 1.4 percent increment across both countries.”

They apparently just averaged the two numbers, without considering that the US has a population more than twice that of Mexico. That ends up being a bigger number and sounds scarier than if they had factored in population. That is, the proper way to calculate the average would be a population weighted-average, which they didn’t do! That doesn’t give me a lot of confidence that this was a well constructed experiment and the conclusions were objective.

It is not uncommon for the US to experience a temperature range of about 50 deg C from Winter to Summer. Using their numbers, that suggests a 35 percent increase in suicides during the Summer. That doesn’t quite pass the smell test. The FBI has documented increases in homicide in the Summer, but I don’t think it is anywhere near 35%.

They apparently only looked at raw temperatures, and not the heat index. Everyone knows that humid weather is more oppressive. Again, an indication of a poorly thought out and executed experiment. Lastly, as is all too often the case with ‘research’ associated with climate, there is no mention of error bars or confidence intervals.

Stanford is not the University I used to know!
