Increased temperatures contributed to more than 200,000 cases of kidney disease in 15 years in Brazil alone, world’s largest study finds

World’s largest study of the impact of temperature changes and kidney disease reveals that 7.4 per cent of all hospitalisations for renal disease can be attributed to an increase in temperature

Peer-Reviewed Publication


Professor Yuming Guo

Today the world’s largest study of the impact of temperature changes and kidney disease reveals that 7.4 per cent of all hospitalisations for renal disease can be attributed to an increase in temperature. In Brazil – where the study was focused – this equated to more than 202,000 cases of kidney disease from 2000-2015.

The study, led by Professor Yuming Guo and Dr Shanshan Li, from Planetary Health at Monash University and published in The Lancet Regional Health – Americas journal, for the first time quantifies the risk and attributable burden for hospitalizations of renal diseases related to ambient temperature using daily hospital admission data from 1816 cities in Brazil.

The study comes as the world focuses on the impact of climate change at the COP26 conference in Glasgow from 31 October.

In 2017, a landmark article in The Lancet declared renal diseases a global public health concern, estimating that almost 2.6 million deaths were attributable to impaired kidney function that year. Importantly the incidence of death from kidney disease had risen 26.6 per cent compared to a decade previously, an increase that this study may indicate was, in part, caused by climate change.

The study looked at a total of 2,726,886 hospitalizations for renal diseases recorded during the study period. According to Professor Guo, for every 1°C increase in daily mean temperature,  there is an almost 1 per cent increase in renal disease, with those most impacted being women, children under 4 years of age and those 80+ years of age.

The associations between temperature and renal diseases were largest on the day of the exposure to extreme temperatures but remained for 1–2 days post-exposure.

In the paper the authors – who are also from the University of Sao Paulo – argue that the study “provides robust evidence that more policies should be developed to prevent heat-related hospitalisations and mitigate climate change.”

“In the context of global warming, more strategies and policies should be developed to prevent heat-related hospitalizations.”

The authors advise interventions should be urgently incorporated into government policy on climate change, including particularly targeting specific individuals, including females, children, adolescents, and the elderly, as they are more vulnerable to heat with regard to renal diseases.

“Moreover, attention should be paid to low- and middle-income countries like Brazil, where reliable heat warning systems and preventive measures are still in need,” Professor Guo added.

Yes ,but nowadays you ain’t no real scientist if you don’t pull something out of your ass that can be blamed on global warming.
(This is the scientific version of “Trump is H!tler”.It is an elementary statement for the woke reputation )

And this one from a country that lost this year huge parts of crops and coffee trees as result of a cooler climate.

Imagine you would blame the kidney diseases on vaccines or the fat corrupt chick that ruined the country for years.
Your carreer would be over in a second.
But use the Paul Ehrlich Methodology of scientific doom to push an agenda and you will be a hero,nomatter how incompetent you are.

You cannot see other people’s perspective so you cannot appreciate humor.
Humor relies on double meanings, and an overall grasp of a social context.
The self-centered, self-important person has one context.

A psychiatrist blogger, “The Last Psychiatrist,” explained narcissism as seeing the world, including your entire life, as if you are the central character in a movie, and so everything is valued only vis-a-vis your interests or desires. You in fact have this world-as-movie psychology to sustain the regular need for admiration.

IMO, some people experience childhoods that may make them be genuinely narcissistic. But I also believe that we are rasing people to have a condition mirroring narcissism: this view of always being right, always watching out for how you are being aggrieved, always being catered-to, and so on.

I do a lot of research training with young adults. With some, you have to be quite brash to get a direction or instruction through to them. And, of course, your evaluation from them is a leading metric of how well you did on your role.

So, when you are the first person to wake someone up, metaphorically, to teh real world, you look like your are the worst trainer / mentor.

They are humorless because they are busy being SJW.

You have zero knowledge about human physiology, do you? Diabetes is caused by fatty acid accumulation in muscles and liver. DAGs block insulin signaling pathways, which hinders GLUT4 translocation in muscles and down regulating of glucose production in liver.

Dietary meat, eggs and dairy are the main source of saturated fat consumption, which is responsible for the increase in hypertension, hypercholesterolemia and diabetes, all of which drive kidney disease.

The average US citizen consumes a staggering 2.6 pounds of meat, eggs and dairy per day.

Peter asks:
”Did the researchers cross-check the day of all 2.7 million hospitalizations with the local temperature at the time of hospitalization?”

And the answer is actually yes. If you bother to read the paper you would see that that is exactly what they did. Fig. 2 of their paper shows a monotonic increasing risk of hospitalisation for kidney disease with daily mean temperature. The risk then drops back down to normal after about 3 days (Fig. 3). In Brazil for whatever reason the hotter the daily temperature the more likely it is that you will be admitted to hospital due to a renal failure.

Again look at the paper. Fig 2 shows that the risk increases monotonically with temperature starting from 5 degrees (relative risk of 0.8) to 35 degrees. I doubt if anyone is going to the hospital for the airconditioning when the temperature is 20 degrees.

They say “Confounders like age, sex, income, and lifestyle, which unlikely change in such a short period, can be effectively controlled by this method with the self-matched design.”

Firstly, the major confounding factor of diabetes wasn’t even looked at.


We have “BackgroundBrazil is one of top 10 countries with the highest number of people with diabetes mellitus (DM), affecting 16.8 million peoples. It is estimated that 7.7 million people (20–79 years) in the country have not yet been diagnosed, representing an under-diagnosis rate of 46.0%. Herein we aimed to screen people for high blood glucose or risk for developing type 2 DM (T2DM) through community pharmacies in Brazil.”

And if you look at this
you can see the incidence of diabetes is increasing quickly.

This is a rubbish paper.

Does it make you even slightly suspicious when a change of 1゚- Which is not humanly perceptible – Is being cast as a causal factor in kidney failure? The temperature change when you go from one room to another is more. The temperature change when you go from the shade to a sunlit area is more.

The temperature change on a cloudy vs sunny day is MUCH more.

This study reminds me of the sea level study that was claiming a sub-millimeter increase in sea level rate of change is happening based on measurements with multi-meter margins of error.

What would we do without studies? Studies are a dime a dozen and you can get one to say anything you want. Two years from now, when renal cases start fall, they’ll blame that on warmer temps as well.

Heck, we’ve all heard about how warmer temps are going to cause severe wind storms and increases in hurricanes and tornados. Then wind speeds fell throughout Europe so the wind turbines wouldn’t produce power. So, they came out with a new study that said – guess what – global warming causes lower wind speeds. Presto.

Sadly, it is far more likely that global temperatures will start to fall than renal failure!
With increases in diabetes, obesity, the use of OTC anti-inflammitories and increased reliance on highly processed foods full of empty carbs and vegetable oils; the incidence of renal failure will continue to grow! If only it was temperature related, then a little AC could cure it!

October 31, 2021 7:48 pm

So divided over the number of days in the year and divided over the 1816 cities taking part in the study makes it 4 hospitalizations per day per city. 4 per city per day plus 1% is?
When it gets warmer people drink more. I have never been there but my sister lived there for a couple of years and it would seem that the drinking water there is not necessarily all that clean. Drinking more unclean water leads to more kidney problems, amongst other things, according to WHO.
In the meantime the population increased by 23% over the last 20 years and having days of more than 100F in Rio is not uncommon in summer.
Yes I would expect an increase in renal failure on warm days if the population increased by that much and the water quality does not get sorted.

Nomore suspenders, What Am I Like…..

A nugget concerning Monsanto (and boy-oh-boy have they got some explaining to do when ‘they’ meet my namesake (up) at The Pearly Gates)

Elmore, a historian at Ohio State University and author of “Seed Money: Monsanto’s Past and Our Food Future,” said the Monsanto-Coca-Cola relationship can be traced back to the companies’ beginnings.

“If not for Coke, there would be no Monsanto,” Elmore told Rogan. “In the early 1900s, Monsanto was nothing. They were on the verge of going out of business. One giant contract saved them, and eventually allowed them to grow into the giant they are today.”

What was that contract? “Monsanto supplied Coca-Cola with their artificial sweetener, and their caffeine,” said Elmore.

Elmore explained:
“To make enough caffeine for Coca-Cola, Monsanto bought the damaged tea leaves from the global tea trade and processed out the caffeine and sold it to the soft drink giant. Then Coca-Cola needed so much caffeine that excess tea leaves wouldn’t cut it — so Monsanto began developing a synthetic caffeine from coal tar, a byproduct of coal.”

So maybe not ‘coal’ directly directly – it’s all the refined sugar that comes with the coal derivative that’s taking them down.
Someone in this thread alluded to that and is what reminded me…
(Wonders if Carrie chowed down on coal when she was preggers, do girls still do that?)

Oh no, not Real Sugar but ‘Artificial Sweetener‘ = even worse as now generally now regarded as perfectly hideous stuff.
Tiz because its attempts to fool the brain perfectly backfire and when ‘the brain’ next gets a chance of eating real sugar, it noms down 3 or 4 times more than it otherwise would have done..

Let’s see!
Renal failure is caused by diabetes, high blood pressure, obesity and smoking; among others! So even if the rates of those are rising around the world, we’re going to attribute it to a rise in temperature so mild that no one noticed!
This would be like blaming the meteoric rise in obesity and diabetes rates on too much fat! Oh wait, they already tried that! Mixing climate alarmism into medicine will only serve to discredit both, and the medical profession can ill afford it after the way they have so grossly mishandled the Chinese virus!

From the paper we have “Heat-induced sweating and following dehydration are believed to play a vital role in the development of temperature-related renal diseases.”

It sounds like this one can be mitigated by drinking more when its hot.
Also single events dont bring it on, its an over time thing.
In most cases, kidney failure is caused by other health problems that have done permanent damage (harm) to your kidneys little by little, over time.”

This is correlation, not causation. The causation is that people aren’t looking after themselves properly over the long term. Arguably primarily an education issue not a climate one.

November 1, 2021 1:39 am

Increase temperature didn’t lead to higher rates of kidney disease.
Short term increases in temperature [“heat wave” if you are an eco-warrior] lead to higher hospital admission rates. Makes sense, if you’ve got dodgy kidneys higher temperatures will put them under stress.

Not “new” news…

This comment…”According to Professor Guo, for every 1°C increase in daily mean temperature, there is an almost 1 per cent increase in renal disease, with those most impacted being women, children under 4 years of age and those 80+ years of age”… is garbage.

There is no way on this little round planet that an increase in temperature over a few days is going to cause kidney disease. It might lead to an increase in hospital admissions. A crap diet full of sugar and feijoada [mostly salt with beans and whatever else is left around the house] over years certainly will.

Teach the people to drink more when it’s hot.

Pesticides and heavy metals have been attributed as the cause of kidney disease elsewhere in the world.

Of course thirst, dehydration is one cause, but dont you think these people know how to drink when they are thirsty?

There is no reason to attribute this to temperature then.

Old people often have problems to realise to be thirsty.

I take it that they didn’t select Brazil for any special reason and that they will now carry out studies in a whole lot of other countries, just to confirm that the link they claim tio have found in Brazil can be found anywhere else in the world.

Define kidney disease. Is it renal failure or kidney stones or cancer?
Renal failure has five stages the latter stages require dialysis or transplant. Diabetes and other conditions can cause renal impairment.

I call complete BS on this. When the “scientists” are proved wrong I will endeavour to ensure one way or another that their careers are destroyed and their names are crap as should every reasonable scientists out there. And I’ll dump on the Lancet in every way possible. Utter nonsense that these conclusions are correct given that we have had only just over 1 degC warming since 1900. Meta analysis hey? “In the context of global warming, more strategies and policies should be developed to prevent heat-related hospitalizations.” And who should make more $ out of the strategies and policies? Perhaps the authors of the meta analysis report. THis study encapsulates everything wrong with climate change science.

November 1, 2021 4:39 am

Is this a fair summary? Are they really saying that hospital admissions for renal disease go up when it’s hotter, therefore heat causes renal disease? This is what climate science has been reduced to?

I’ve traveled to Brazil regularly since 1992. My many trips to popular beaches tell me for certain that obesity in the population has become much more common in Brazil since 1992. It is likely that type 2 diabetes is the biggest cause for greater kidney disease. Brazilians now spend much more time under air conditioning than in 1992, so the suggestion that people (and kidneys!) are now more heat stressed than 25 year ago is simply silly. The paper is garbage.

So Miami and Los Angeles have significantly higher rates than NYC? Or is it only “climate change” degrees that matter?

You don’t have clean drinking water and the temperature goes up. Hence, you drink more water and get renal failure ending up in the hospital. Let’s try to stop temperature rise instead of getting people clean drinking water.

Access to inexpensive, clean drinking water would do more to increase human health than almost any other endeavor imaginable! But the portion of the climate catastrophe funding needed to address it might put a crimp is some activist’s funding for their latest paper on the sins of CO2; can’t have that!
Just remember, the people who suffer most from poor water quality are Third Worlders of color; they are of no concern to alarmists, except when they can be utilized for political gain!

Maybe I read this wrong but from the OP it seems like 200,000 people were hospitalized with heat-related symptoms from unusually hot days (weather).

And while in the hospital it was discovered they had renal issues.  

So unusually hot days allowed 200,000 to learn they had some form of renal problems that may otherwise not have been discovered prior to causing symptoms.

Or maybe I missed something.

There is no way that a 0.5 deg C warming could be linked to kidney problems. Attribution is impossible, particularly as there is such a seasonal variability even in the Amazon. Just cannot be done.

Add to this that we are not warming and the whole claim crashes. More likely, many people have moved into the cities and they are suffering from various forms of pollution, which does not include warming or CO2.

Clyde Spencer
November 1, 2021 8:43 am

Today the world’s largest study of the impact of temperature changes and kidney disease reveals that 7.4 percent of all hospitalizations for renal disease can be attributed to an increase in temperature.

Let’s get real! The average global temperature is increasing about 0.1 deg C per decade. Most of the increase is in the daily lows, meaning at night and in the Winter when temperatures are lowest. The Arctic is apparently the fastest warming region on Earth, biasing the global increase upwards. In other words, there is little reason to believe that those living in Brazil are being heat-stressed significantly more than 15 years ago. I present evidence here that there is little basis for the claim that heat waves in the US, and by extension, elsewhere, are increasing:

I suspect that these researchers are being misled by spurious correlations. By being quick to blame global warming, it deters research into what might actually be responsible for an increase in renal disease, such as diabetes.

The link to the article is invalid, so I can’t see what the authors actually said.

November 1, 2021 8:43 am

These knuckleheads. They can never get it through their thick heads that CORRELATION DOES NOT EQUAL CAUSATION.

How the hell can these “scientists” measure the effect on renal disease due to a temperature that has only increased about 1 degree C in the last 170 years? Pretty sure that in Brazil in 1850 physicians weren’t even diagnosing renal problems, because most people died there and then due to communicable diseases and accidents in the Amazonian frontier 170 years ago.

Well, since a whole raft of other things in Brazil and the world have increased during the same timeframe, but at vastly greater rates than did temperature, then we must be able to conclude that renal disease is correlated with:

  • Listening to/watching electronic communications (radio, television, and now internet)
  • The increase in knowledge of medical science
  • The average speed of transportation, from horse drawn carriages and foot to rocket ships
  • The expansion of colleges and universities
  • The expansion of democracies
  • The invention of pop culture
  • The literacy rate
  • The extension of human life expectancy
  • The reduction in infant mortality

On and on and on.

Really … like shooting fish in a barrel.

It also correlates to the increase in movies based on Marvel Comics superheroes. Should we consider that to be causation, too? Just asking for a friend who likes to see hard evidence of cause.

And is it really heat, or just access to potable clean water?

From the above article:

“World’s largest study of the impact of temperature changes and kidney disease reveals that 7.4 per cent of all hospitalisations for renal disease can be attributed to an increase in temperature”

Hmmm . . . just wondering what the percent increase in all hospitalizations, over these same 15 years of study, would be from just the increases in (1) obesity, or (2) longevity. Or do these factors not affect renal disease?

More importantly, by what process did the Monash University researchers separate out increasing temperature as an independent cause of hospitalization when it is so intimately correlated with all other possible factors that were simultaneously increasing over that same time period.

In simple English: correlation does not necessarily equal causation . . . and the researchers failed to address this fact . . . “robust evidence”? Pfttttpph!
