CO2 ppm is not likely to reach 1,000 ppm at any time , as the human world and it's economy would fall to bits well before then.

I once - about 30 years ago - did a model on population and existing death rates in a very, very bad place on the planet. The model predicted that there would be no adults alive within 20 years - it was wrong - reductio ad adsurdum and all that..

Sorry if any of these has been posted before. They probably have...

Soil warming enhances the hidden shift of elemental stoichiometry by elevated CO2 in wheat.
https://www.nature.com/articles/srep23313
Quote
Increase in atmospheric CO2 concentration ([CO2]) and associated soil warming along with global climate change are expected to have large impacts on grain mineral nutrition in wheat. The effects of CO2 elevation (700 μmol l−1) and soil warming (+2.4 °C) on K, Ca and Mg concentrations in the xylem sap and their partitioning in different organs of wheat plant during grain filling were investigated. Results showed that the combination of elevated [CO2] and soil warming improved wheat grain yield, but decreased plant K, Ca and Mg accumulation and their concentrations in the leaves, stems, roots and grains. The reduced grain mineral concentration was attributed to the lowered mineral uptake as exemplified by both the decreased stomatal conductance and mineral concentration in the xylem sap. These findings suggest that future higher atmospheric [CO2] and warmer soil conditions may decrease the dietary availability of minerals from wheat crops. Breeding wheat cultivars possessing higher ability of mineral uptake at reduced xylem flux in exposure to climate change should be a target.

Found that one while searching searching for this:
Hidden shift of the ionome of plants exposed to elevated CO2 depletes minerals at the base of human nutrition.
https://elifesciences.org/articles/02245
Quote
Mineral malnutrition stemming from undiversified plant-based diets is a top global challenge. In C3 plants (e.g., rice, wheat), elevated concentrations of atmospheric carbon dioxide (eCO2) reduce protein and nitrogen concentrations, and can increase the total non-structural carbohydrates (TNC; mainly starch, sugars). However, contradictory findings have obscured the effect of eCO2 on the ionome—the mineral and trace-element composition—of plants. Consequently, CO2-induced shifts in plant quality have been ignored in the estimation of the impact of global change on humans. This study shows that eCO2 reduces the overall mineral concentrations (−8%, 95% confidence interval: −9.1 to −6.9, p<0.00001) and increases TNC:minerals > carbon:minerals in C3 plants. The meta-analysis of 7761 observations, including 2264 observations at state of the art FACE centers, covers 130 species/cultivars. The attained statistical power reveals that the shift is systemic and global. Its potential to exacerbate the prevalence of ‘hidden hunger’ and obesity is discussed.

By 2100 we're looking at 1000ppm of CO2 in our atmosphere. For our entire history as a species, we've been at 280ppm or less.
Not sure how you are arriving at the figure.  From 1980-2010, the atmospheric CO2 level increase 50 ppm.  Even accounting for an upward rise from that trend (and no mitigating efforts), the maximum value we would reach by 2100 is 600 ppm.  No detrimental health effects have been documented at the level.

You may have missed the acceleration of the annual increase in CO2. 600 ppm is more like a minimum, if the acceleration stops and the rate of increase remains at 2.25-2.5 ppm/year.
But human population is growing, affluence is growing in parallel, and this is how the IPCC got to >900 ppm by the year 2100 in RCP 8.5 - the non-mitigation scenario. Not to mention natural positive feedbacks that could kick in (or perhaps have already kicked in). So it's not as clear-cut as you claim it to be.



Yes, we will reach that level, using the worst-case, least likely scenario.  Population cannot continue to rise exponentially.  Hence, the most likely value is around 600 ppm, provides no significant mitigation occurs.  Personsally, I do not believe this will continue, as future generations are likely to take greater action.

While your vague reassurances are vaguely reassuring, I'd much prefer seeing actual research on the subject. Given that the survival of the species is at stake.

We're not sure if healthy infants can be gestated and raised in the atmosphere as it will be in 2100.

Maybe we should put some effort into finding out, given the importance of the issue.

That would be nice, but it may be impossible.  It is difficult to measure the effects of someone living in an environment that does not exist today.  Past research has shown the effects of moving from one level to another, but cannot simulate assimilation.  This is different than elevation effects, which can be measured for both effects.  We do not know how the body will acclimate I the long run.

Multigenerational lab rat experiments would seem to be a good start. I'm sure professional biologists and pediatric pulmonologists would be able to suggest a wide range of experiments which would help to figure out how resilient we are to the conditions we're creating.

It seems like it's important enough to know whether we're able to survive the atmosphere we're creating that we might not want to just give up before we've even started looking into it.

That's what the rest of the animal kingdom is doing, so why shouldn't we. That would be the 100%  natural and organic approach. Ignore the dangers and just keep consuming and reproducing like there is no tomorrow./s

Multi-part article on the effects of air pollution in locations around the world.  Not specifically climate change related, but it addresses many of the same themes we discuss here: cars, bikes, urban pollution, etc.

92% of people globally live in places with dangerous levels of air pollution.
Here are some of the stories
Quote
Every year, millions of people die as a result of air pollution-related illnesses. According to the World Health Organization, 11.6 percent of all deaths worldwide are associated with air pollution, making it almost as deadly as tobacco.

Flu Weather: It's Not the Cold, It's the Humidity
Quote
Laboratory and epidemiological studies increasingly agree that the flu is transmitted more readily when the [Relative Humidity] RH is low. At higher RH, the virus appears to be less stable, and the small virus-bearing droplets sent into the air by a cough seem more likely to attract water vapor and fall out of the air before infecting someone else. There’s also evidence that the flu grows more readily in the upper respiratory tract when it’s dry.

Experts agree that the atmosphere is not the main factor driving a flu outbreak. Instead, weather is more of a precondition that can leave the door open for flu to spread more easily. The moisture effect may not be large, but it’s robust and significant...
...
“We don’t have the airtight evidence that a humidifier reduces your chance of getting sick, but we know that dryness is bad for you,” Barreca told me. Low relative humidity can dry out your nasal passages, making you more vulnerable to the flu virus and other bugs. Dehydration can also stress your cardiovascular system, noted Barreca. And there’s the greater likelihood that the flu virus will survive its trek from one person to another. Very high humidity can be a problem in itself, raising the risk of mold and other issues, but a midrange relative humidity of around 40% to 60% appears to be a sweet spot for overall health. ..

CLIMATE CHANGE IS CAUSING A DANGEROUS UPTICK IN CASES OF LYME DISEASE
Ticks that carry the pathogenic bacteria can now survive in environments where they previously would've frozen to death, resulting in an increased risk of infection.

I had Lyme disease...the worst thing I have ever had and that includes cancer...right side of my face was paralyzed for almost 6 months...have severe arthritis in my hip where the bite was.

I still go to Wisconsin where I contracted it but bathe in insecticide before taking hikes.

Ultimate irony:  the Lone Star tick causes an allergy to one of the Lone Star state’s prize industries — beef.  Infected hosts who eat red meat can experience violent reactions bad enough to require hospitalization.

As you read this, millions of tiny, black-and-brown-legged creatures are beginning to reawaken after laying dormant underneath layers of last year’s leaf cover.

Ticking Meatmares
Lone Star ticks — which now live from Texas to Maine — hunt in packs and spread an allergy to beef and pork. Thanks to climate change, they're spreading.
Quote
Blacklegged ticks behave in relatively predictable ways — they hang out in leafy undergrowth, arms and legs outstretched in case a hapless animal or humans passes by.

…one of the tick’s favorite hosts, the white-tailed deer. Deer can travel several miles in the days or even weeks it takes for lone stars feed on them, eventually dropping the ticks a long way from where they first picked them up. Reforestation efforts in the eastern U.S. that began in the 20th century, coupled with a slump in hunting, have led to an explosion in white-tail deer populations. The growth of suburbs means there are plenty of people pressed up against these wooded areas. …

Diseases Spread By Insects Have More Than Tripled, CDC Says
Quote
In the United States, diseases spread by mosquito, flea and tick bites tripled from 2004 to 2016, federal health officials say in a new report. During that time, there were more than 640,000 cases of vector-borne diseases. …

So the spread of blacklegged ticks would be a negative feedback as infected people will reduce there consumption of meat.

https://www.nbcnews.com/better/diet-fitness/vegan-eating-would-slash-cut-food-s-global-warming-emissions-n542886

"When it comes to climate change, following dietary recommendations would cut food-related emissions by 29 percent, adopting vegetarian diets would cut them by 63 percent and vegan diets by 70 percent."

Well, it’s the Lone Star tick that causes the meat allergy, but yes, climate change may indirectly be leading to a slight decrease in meat consumption, which would decrease CO2 emissions. (Related discussion in the Becoming Vegan thread.)

Hay fever on the rise...https://qz.com/766386/climate-change-hay-fever-seasonal-allergies-europe/

Old article but yeah, i should have read that 2 years ago because i since have the allergy it seems.
And it had me fooled thinking about flu, pollution or whatever.
So i focused on healthy diet and spending more time outdoors doing research only to see it get worse and worse haha  :P
Now, this climate change health victim keeps an eye on the pollen readings for sure.
Along with the heatwaves and sun giving me allergic reactions on the skin already, it is a pain in the ass...hope it rains all summer.

Preparing for the health impacts of a fiery future
Quote
Consider this: last year’s wildfires in Northern California produced the highest levels of pollution ever recorded in the area. In just two days, those fires produced as much pollution as all the state’s cars do in a year.

Wildfire smoke is laden with particulate matter, which triggers asthma, worsens lung and heart disease, and is linked to premature births and low birth weight babies.

And, as fires incinerate everything in their path — including plastics, paints and pesticides — they release toxins into the environment. In Sonoma County last year, for example, melted plastic pipes may have contaminated drinking water with benzene.

The health impacts of wildfire travel long distances: smoke from last year’s Northern California wildfires was detected more than 500 miles away in Mexico. In 2002, smoke from fires in Quebec drifted down the U.S. East Coast, causing a nearly 50 percent increase in hospital admissions for respiratory disease. ...

U.S.:  Heat Wave Safety: 130 Groups Call for Protections for Farm, Construction Workers
As outdoor workers labor in extreme temperatures, they are vulnerable to heat-related illnesses that can be fatal. Climate change raises the risks.
Quote
Parts of the country are expecting another round of searing, potentially record-shattering heat in the coming days, and many farm and construction workers will be out in it—with no federal heat stress standards directing their employers to offer them water, rest or shade.

Despite recommendations going back more than 40 years, the federal government has repeatedly failed to set a heat stress standard for American workers.

On Tuesday, the consumer advocacy group Public Citizen, along with United Farm Workers Foundation and Farmworker Justice, joined more than 130 public health and environmental groups in submitting a petition to the Occupational Safety and Health Administration calling for the agency to require employers to protect their workers from heat by imposing mandatory rest breaks, hydration and access to shade or cooled spaces, among other measures.

"This is a public health issue. This is a justice issue. The people who feed us, who feed America, deserve strong protections from the effects of climate change," said Jeannie Economos, a project coordinator with the Farmworker Association of Florida. "We're calling on OSHA not to delay anymore."

As global warming continues, extreme heat is expected to become more common, and the plight of outdoor workers will get more extreme along with the weather, making stronger standards more critical.  From 1992 to 2016, heat killed 783 workers in the U.S. and seriously injured nearly 70,000, according to the group's new analysis of working conditions in high temperatures.

Those numbers, the report said, understate the total. In 2011, Public Citizen petitioned the agency for a heat stress standard, and in response, OSHA acknowledged that heat-induced "deaths are most likely underreported, and therefore the true mortality rate is likely higher."

Farmworker advocacy groups have noted that migrant workers are especially reluctant to insist on breaks or water, and that illnesses and deaths from heat are likely underestimated because undocumented workers fear retaliation or deportation. ...

"Algae Bloom - Why Is It So Dangerous?"
https://www.acsh.org/news/2018/07/16/floridas-deadly-algae-bloom-why-it-so-dangerous-13188

Good info on the various types of bacteria that makeup algae blooms.
Quote
Here are three neurotoxins produced by blue-green algae. They all operate by different mechanisms and are all quite deadly central nervous system poisons.
1. Anatoxin-a, which also goes by the rather disquieting name of Very Fast Death Factor (VFDF), was the first cyanotoxin to be isolated and identified in 1972. Despite its very simple chemical structure, it packs quite a punch. VFDF is a powerful neurotoxin because it binds very tightly - more so than the natural neurotransmitter acetylcholine - to the nicotinic acetylcholine receptor in the neural synapse. Symptoms of toxicity include:
    Loss of muscle coordination
    Muscle tremors
    Convulsions
    Paralysis
    Respiratory distress
Death from respiratory failure typically occurs within 2-7 minutes.

2.     Lyngbyatoxin-a is a chemical defense weapon produced by certain strains of cyanobacteria to prevent it from being eaten by fish. Its toxicity is very different from that of anatoxin-a:
    A potent skin irritant and a vesicant (causes blisters). It causes "seaweed dermatitis".
    Severe gastrointestinal damage when consumed, which can be fatal.
    It is both a carcinogen and tumor promoter.

3. Saxitoxin (1) is also known as Paralytic Shellfish Poison (PSP).
Transmembrane proteins can be thought of as gates; when the gate is closed ions cannot enter or exit cells and when it is open they can. This flux of sodium and potassium ions into and out of cells - it can be thought of as a molecular switch -  is a fundamental mechanism that regulates nerve function. So not surprisingly when this mechanism is perturbed very bad things happen. This is reflected in some of the symptoms of PSP:
    Tingling
    Vomiting
    Diarrhea
    Abdominal cramps
    Headache
    Dizziness,
    Muscle weakness
    Disorientation
    Memory loss
    Loss of coordination

And in serious cases:
    Seizures
    Unstable blood pressure
    Paralysis
    Difficulty breathing,
    Coma
    Death

Bon Appetit!
Science is a thought process, technology will change reality.

Blue-green algae, aka Cyanobacteria are being seen more than ever in Holland.
It's not a new thing, but the scale is.
Mostly dogs get sick as they are always jumping in the water or encouraged to by their owners.
People are jumping into unhealthy waters more as well due to the heatwave.
The pollution gets them hospitalized as well.
The air is very bad as well, still more complaints about pollen/pollution including myself.

Japan Heat Wave Kills at Least 12 Just Days After Deadly Floods

https://weather.com/safety/heat/news/2018-07-18-japan-deadly-heat-wave

Quote
At least 12 people died and as many as 10,000 were hospitalized during an ongoing heat wave in Japan.
Temperatures have soared as high as 105 degrees as the dangerous heat persisted.
The sweltering heat has impacted some of the same areas as last week's deadly flood.

I don't know where else to put it. Perhaps we need a "Heatwaves" Thread.

In South Western Ontario I've been observing far fewer flying insects, fewer birds, and large increases in blue green algae.
I'd noted the problems with insects and birds in previous years, but this is the first year I'd noticed the algae. Lake Erie at Port Dover is clear but many of the ponds and small lakes just to the north are completely matted over.
I've put just over a thousand miles on a new vehicle without needing to wash any bugs off the windshield. :-\

Papers in Holland report today that ticks causing Lyme disease are not affecting us due to the drought, they need to move deeper in the leaf layers to avoid drought themselves it seems.
Snakes such as Natrix natrix however are being seen a lot more, even in people's houses.
A lot of Dutch people don't know there are snakes here and freak out seeing one.
Wasps are said to be doing well.
Spiders are also seen more in houses...now that is scary!
Hedgehog sanctuary is reporting twice the normal amount of hedgehogs in trouble being brought.
They ask people to not do so and leave them alone because species like that are just more visible scrounging around.
My camera trap this week appears to confirm that, a fat hedgehog:

I very rarely see them myself or recorded on cam.
Filmed a polecat as well for the first time ever in the same location:


I did use bait(apple, peanut butter, jam) which seems to attract them looking for scarce food.
Vegetation is dead and therefore other food sources, i would normally expect to film mostly foxes.
Overall my impression is pretty grim for nature.
Hunting, poaching, industrial activity is a known problem but this drought on top of it seems bad if we don't cherry pick sightings like this...i see very little evidence of anything doing well.
Food will be very scarce this winter i fear.

In South Western Ontario I've been observing far fewer flying insects, fewer birds, and large increases in blue green algae.
I'd noted the problems with insects and birds in previous years, but this is the first year I'd noticed the algae. Lake Erie at Port Dover is clear but many of the ponds and small lakes just to the north are completely matted over.
I've put just over a thousand miles on a new vehicle without needing to wash any bugs off the windshield. :-\

Awww Terry!

It is your consumption of vehicles that wipes out insects and makes this planet less liveable lol!
I'm just yanking your chain, don't get upset please.
It's true, i see very few insects as well here.
Mostly industrial humans who can't handle the heat..rows in the street.
I saw the armada of council vehicles coming by pretending to mow the dead grass 3 x in a row.
I saw the poisons being spread again.
That astonished me most as they kill the rare daisies or dandelions even trying to feed the insects...what insects?
Peace bro

Very nice videos!!


I had a camera with that feature many years ago, but the resolution was terrible. I did however catch the kid next door using and abusing my pool while we were gone for the weekend. >:(


The loss of insects here is beginning to freak me out - can't be good for whatever future lies ahead.

Japan Heat Wave Kills at Least 12 Just Days After Deadly Floods

https://weather.com/safety/heat/news/2018-07-18-japan-deadly-heat-wave

Quote
At least 12 people died and as many as 10,000 were hospitalized during an ongoing heat wave in Japan.
Temperatures have soared as high as 105 degrees as the dangerous heat persisted.
The sweltering heat has impacted some of the same areas as last week's deadly flood.

I don't know where else to put it. Perhaps we need a "Heatwaves" Thread.

I agree!  Feel free to re-post here:  https://forum.arctic-sea-ice.net/index.php/topic,2352.0.html

Terry

Ha ha Terry, that's funny...damn kids!
These gadgets have gotten a lot better yes.
I do film people as well doing stuff they aren't supposed to be doing...most places where i would like to record wildlife i can't because of theft or vandalism.
They are over rated anyway and miss most species even in a safe place.
They shouldn't be used exclusively when doing inventory like happens more and more these days.
Tracking and local knowledge provides far more information.
I'm no entomologist but i do notice a thing or two about insects as well of course.

Tthe difference between the city area and surrounding nature areas is striking, nothing left in the city at all where until recently it was always bees, moths, butterflies etc.

in the nature areas very very few remain as well, seen a butterfly or two and a few grasshoppers.
Bee/wasp/hornet species are gone it seems, i only see the fat bumblebee type.
I'm used to finding nests dug out by honey buzzard, badgers or other martens but not seen that either this year.
It's worth noting that the famous German study that reported 75% insect loss was done in a nature reserve, so it's worse elsewhere.
A similar Dutch report shortly after concluded a loss of 67%.
So called "invasive" plant such as wild cherry are being massively attacked and poisoned but entomologists have finally understood that they are a crucial species for at least 56 types of insect.
I could have told them that!
I foraged the cherries for years by shaking the trees out on a tarp and then leave it laying around for all the bugs to crawl away before packing up.
I won't be doing that this year, what little cherry trees remain are bone dry anyway.
This meddling with vegetation is a big contributor to insect loss i believe.
A species such as wild cherry is actually not a new invasive species, but one that was introduced and applauded in the 16th century...of course insects and other wildlife would have adapted to a great food source.

The use of poison has to be a major factor, in agriculture of course but that is pretty well known.
It's everywhere though, nature management organisations do it while believing they can recreate the vegetation of centuries ago amidst a climate crisis.
So areas are logged, poisoned, replanted with beech or similar trees that really don't have much chance while the food chain is interrupted more and more.
When the fences are removed and i have a look, i see voles and mice with no flight response, literally trying to crawl on my shoes and falling over dead...small wonder we lose the insects too.
People themselves poison everything, hunters do as well, schools, offices...all poisoning and adding more concrete of course.
People are asked to report "invasive" plants in their backyard...city will come and poison it for you!
Never mind resistance developing, public health, climate adaptation...urbanization, industrialization first.

What i did find in pretty astonishing numbers are the wood ant nests which were officially down to a single nest.
I don't take that as a sign of their success either though, just a lack of fieldwork.
Nobody here but me and one or two others still doing fieldwork.
One guy studying fungi, another studying bats...that's about it.
Both reporting severe loss as well.
And my research is paralyzed by the heat and allergies...just hiding in my house at the moment.
The entire ecosystem is probably going down just as the insects are.

Climate Connection: Unraveling the Surprising Ecology of Dust
As droughts intensify and development expands, the amount of dust blowing around the earth is increasing, affecting everything from mountain snowmelt to the spread of disease. Scientists are just beginning to understand the complex dynamics of dust in a warming world.
Quote
Although the issue is poorly studied, it’s clear that dust dynamics are shifting in two main ways. Humans are the main cause of an increasing amount of dust in the atmosphere. As farming, grazing, and other development in places such as the Horn of Africa or the U.S. Southwest spread deeper into arid regions, vegetation is destroyed, exposing the soil to wind erosion. In addition, increasing drought due to a warming climate is a major cause of the dust problem, as it kills vegetation and uncaps the soil, allowing it to become windborne.

This has both positive and negative effects. More dust, for example, means more nutrients and minerals, such as iron, are being transported long distances, which stimulates the growth of oceanic plankton — an essential link in the marine food chain. But increasing quantities of dust could cause serious problems for parts of the world, from decreased water flow in some mountain regions to increased human exposure to dust-borne pathogens, a growing health concern. ...

Ebola epidemics don't arise directly from climate change (as far as I know) but as humans intrude on wildlife habitats, such "zoonoses" may become more common.  There's a brand new and rather worrisome epidemic right now:

https://www.npr.org/2018/08/17/639486376/who-expects-ebola-to-spread-in-congo-in-areas-too-dangerous-to-send-workers

"security concerns in the Democratic Republic of the Congo's North Kivu region were preventing aid workers from reaching certain areas — and leaving open the possibility of the Ebola virus spreading. . . At least 1,500 people could be exposed to the virus. . ."

Why the World Is Becoming More Allergic to Food
https://www.bbc.com/news/health-46302780

Quote
Around the world, children are far more likely than ever before to develop food allergies.

The rise in allergies in recent decades has been particularly noticeable in the West. Food allergy now affects about 7% of children in the UK and 9% of those in Australia, for example. Across Europe, 2% of adults have food allergies.

The frequency of food allergy has increased over the past 30 years, particularly in industrialised societies. Exactly how great the increase is depends on the food and where the patient lives.

For example, there was a five-fold increase in peanut allergies in the UK between 1995 and 2016. Australia has the highest rate of confirmed food allergy. One study found 9% of Australian one-year-olds had an egg allergy, while 3% were allergic to peanuts.

It is thought that allergies and increased sensitivity to foods are probably environmental, and related to Western lifestyles.

We know there are lower rates of allergies in developing countries. They are also more likely to occur in urban rather than rural areas.

Factors may include pollution, dietary changes and less exposure to microbes, which change how our immune systems respond.

Extreme Allergies and Climate Change
http://www.aafa.org/extreme-allergies-and-climate-change/

Quote
In 2010, AAFA and the National Wildlife Federation created a report about the impact of climate change on Americans with asthma and allergies. This report talks about how climate change will affect pollen, mold and poison ivy. More pollen, mold and poison ivy can increase the risks for asthma and allergy attacks. Climate change can also make air pollution worse.

Between 1995 and 2011, warmer temperatures in the U.S. have caused the pollen season to be 11 to 27 days longer. These warmer temperatures create more pollen in the air, stronger airborne allergens and more allergy symptoms.

Health effects of increase in concentration of carbon dioxide in the atmosphere
Quote
The lowest value at which the atmospheric concentration of carbon dioxide could be stabilized by reduction of additions made by human activity (fossil fuel-burning, etc.) is estimated as 550 ppm. To achieve this, severe limitations are required on the latter activities. The most often quoted desirable/attainable stable concentration is 750 ppm. This concentration level is not related in any way to health considerations and is above the estimated dangerous level of 426 ppm. The value is also above the 600 ppm level, which results in the ‘stuffy room’ conditions described above. At the very least, 600 ppm of carbon dioxide in the atmosphere will be unpleasant and there will be no readily available means of reversing the changes giving rise to the above symptoms. Such a situation is unlikely to be tolerable for a lifetime by humans (and other mammals with the possible exception of seals) without deterioration in general health along with serious curtailing of physical activity presently taken as normal.
It is likely that when the concentration of carbon dioxide in the atmosphere reaches 426 ppm in less than two generations from the present date(2005), the health of at least some sections of the world population will deteriorate, including those of the developed nations. It is also obvious that if the extremes of conditions described above come to pass, then the biosphere and humankind are seriously threatened.

Obviously we will hit that threshold far earlier, since we are already at 410 ppm and people are already exhibiting signs of Metabolic Syndrome.


The Stress of Global Warming on Human Health: pH Homeostasis
Quote
Significantly, earlier human studies have shown that chronic exposure to CO2 at moderate inspired concentrations alters pH homeostasis, and fosters body CO2 storage at the expense of buffers protein and phosphates in lean body mass, as does higher atmospheric CO2 concentration in the terrestrial biosphere. Increased CO2 stores matching lower bone mineralization characterizes Osteoporosis, a major public health problem whose risks for osteopenia, and non-spine fractures are significantly higher for people with higher percentage of body fat. Increased CO2 storage is present also in obstructive sleep apnea, a prevalent disorder characterized by gradual elevations of the partial pressure of CO2 in the arterial blood, associated with major nocturnal hemoglobin desaturation, higher HbO2 affinity, and repetitive episodes of partial or complete upper airway obstruction. Most individuals with obstructive sleep apnea have metabolic syndrome, term describing the clustering of abdominal obesity with other risk factors for atherosclerotic-cardiovascular disease (ACVD) which show abnormal intracellular ion profile in red blood cells, and sustained cortisol levels as does chronic exposure to increased ambient CO2. Studies suggest that moderately increased endogenous CO2 may oxidize erythrocytes, and promote their suicidal death (eryptosis) which, by fostering the release of pro-inflammatory cytokines throughout systemic circulation, activates hormonal stress response, and results in increased CO2 stores, abdominal fat accumulation, and Metabolic Syndrome. Ominously, Global Warming is an unbearable stress for ecosystems and their member species, just as this cluster of ACVD risk factors is for human health. This review focuses on Metabolic Syndrome and pH homeostasis, the linkage between breathing and feeding via CO2 economy, to disclose the Stress of global Warming on human health.

Earlier human studies have shown that chronic, continuous exposure to CO2 at 0.5-3% inspired concentrations for more than one month alters pH homeostasis and raises body CO2 storage [15,16,17], as does higher atmospheric CO2 concentration in the terrestrial biosphere. Mostly during CO2 exposure, ion profile changes in red blood cells (RBCs); hemoglobin-O2(HbO2) affinity increases with RBCs oxidation; the adrenal cortical response is activated, as measured by increased blood corticosteroid level and lymphopenia; and the partial pressure of CO2 in the arterial blood (PaCO2) rises as CO2 is stored as HCO3- in the extracellular fluid (ECF), and as CO3-2 in bone, at the expense of buffer protein and phosphate in the lean body mass (LBM) [15,16,17]. Continuous CO2 inhalation is commonly thought to be tolerated at 3% inspired concentrations for at least one month, and 4% inspired concentrations for over a week. The effects produced seem reversible, decrements in performance or in normal physical activity may not happen at these concentrations [18].

Thus, it should be noted not only that CO2 levels in poorly ventilated spaces can be found even higher than this range of 3-4%, but also that humans may be chronically exposed to intermittent, not continuous CO2 inhalation, a condition that by inducing mildly increased endogenous CO2 may cause pathological adaptations. In fact, studies show that because of the greater concentration of buffer base, acclimatization to CO2 results in desensitization of dyspnea and in changes of set point for central respiratory controllers such that, on return to “outdoor” air breathing, ventilation may decline below control values even in individuals intermittently exposed to CO2 increase for 13 hours per day [15,19]. Furthermore, chronic exposure to intermittent, mild ambient CO2 increase results also in changes of set point for central feeding controllers which may lead to obesity. In fact, it has been shown that during chronic inhalation of CO2 at 1.5% inspired concentration for more than one month, food intake decreases significantly, by ~30%, but body weight does not change [17]. On return to “normal” air breathing, food intake rises and body weight is gained [20]. Actually, stress is a well known inducing factor of both transient and chronic loss of appetite or overeating [21].

Inhaled CO2 induces the same physiological effects as does metabolically produced CO2, the key chemical messenger gas in the linking of respiration, systemic circulation, and local vascular response, to body’metabolic demands both at rest and exercise [18]. Increased CO2 needs to be removed as quickly as possible because its lowering of blood pH can denature enzymes. A major portion of the physicochemical defenses of neutrality by the buffer systems of the whole body takes place in muscle and bone [24]. Protein from muscle can be released to bind with acids in the blood. This can contribute to LBM loss. Calcium and phosphorus in bones can bind to acidic substances to neutralize them, thereby contributing to bone mineral loss. Suggestively, greater CO2 stores matching reduced bone mineralization characterizes Osteoporosis, a major public health problem whose risks for osteopenia, and non-spine fractures have been shown to be significantly higher for people with higher percentage of body fat [25]. Increased CO2 storage is present also in obstructive sleep apnea (OSA), a prevalent disorder characterized by gradual PaCO2 elevations, associated with major nocturnal hemoglobin desaturation, higher HbO2 affinity, and repetitive episodes of partial or complete upper airway obstruction [26]. Most individuals with OSA have metabolic syndrome (MetS), a common, condition consisting of a constellation of metabolic risk factors for atherosclerosis and cardiovascular disease (ACVD) associated with abdominal obesity, namely, increased plasma glucose values, higher blood pressure levels, higher triglycerides levels, and lower high-density lipoprotein cholesterol (HDL-C) levels [27]. The MetS presents abnormal intracellular ion profile in RBCs, and sustained cortisol levels [28,29] as does exposure to CO2 at 1.5% inspired concentrations for more than one month [17,30].

As stated, CO2 acclimatization to chronic exposure to CO2 at 1.5% inspired concentration results in greater concentrations of buffer base, with the consequent reduction of minute volume ventilation, forced vital capacity, and PaO2 [15]. Beyond that, food intake rises, and body weight is gained, on return to “normal” air breathing [20], as compared to exposure to moderately increased ambient CO2 in which lower (~30%) food intake, without body weight changes, matches increased ventilation [17]. Accordingly, adaptations to chronic exposure to intermittent, mildly increased ambient CO2 may result in lower O2 uptake, reduced metabolic rate, and excess feeding, as it occurs in MetS. Food intake may rise because mildly increased endogenous CO2 enhances the expression of TNF-α and IL-6, which further glucocorticoids release, with consequent higher expression of the oroxigenic NPY. Hence, CO2 does not only determine the need for alveolar ventilation, but it is also the “stress” ruler of both transient and chronic overeating or loss of appetite [21], to normalize/oppose pH changes.

With moderately increased endogenous CO2, as soon as RBCs oxidation threatens pH homeostasis, TNF-α may induce the coincident appearance of MetS ACVD risk factors [97] to restore the lost balance. In essence, TNF-α inhibits auto-phosphorylation of tyrosine residues of insulin receptors and promotes serine phosphorylation of insulin receptor substrate-1; this, in turn, triggers serine phosphorylation of insulin receptors in adipocytes, prevents the normal tyrosine phosphorylation, and interferes with transduction of the insulin signal. Hence, insulin resistance results in Akt (protein-kinase-B) inhibition and subsequent
inhibition of NO-synthase (NOS) [97]. Accordingly, TNF-α promotes adaptations such as insulin resistance-hyperglycemia, NOS inhibition, reoccurrence of glycolysis, and decreased O2 uptake whose joined effects overall reduce RBCs oxidation and maintain blood O2 release. Inflammation is, indeed, a fundamental survival mechanism but it is dangerous when its transient, physiological adaptations are converted to a long-lasting, pathological state. Potential causes for steady CRH activation and glucocorticoids release include environmental stresses, which as explained, result in higher HbO2 affinity and mildly increased endogenous CO2 [23]. Ominously, as atmospheric CO2 increases, Global Warming may threaten human health. Thus, the following reviews the mechanism through which intermittent exposure to mildly increased ambient CO2 may lead to MetS and/or osteoporosis.

Overall, during exposure to mildly raised ambient CO2 levels, slow adaptive processes in electrolyte exchange and pH regulation results in higher PaCO2 due to reduction in forced vital capacity. Presumably, food intake decreases much to reduce PaCO2, and body weight does not change [17] due to the water retention required to hydrate and store the inhaled CO2 as ECF HCO3-, and as bone CO3-2. Basically, with CO2 acclimatization, compensatory processes for respiratory acidosis result in metabolic alkalosis [107] which, on return to “normal” air breathing, constantly triggers glucocorticoids release. In fact, with abdominal accumulation, a lower compliance of the respiratory system causes the decline of forced vital capacity, minute volume ventilation, and PaO2 [15], with ensuing chronic lactate accumulation. This, by raising HbO2 affinity, results in higher PaCO2[49], and RBCs oxidation with TNF-α and IL-6 release from phagocytic cells. Besides, the relentless LBM loss coupled to the body fat gain arisen during exposure to CO2 implies not only that HbO2 affinity rises, and O2 release falls because the loss of body phosphate impairs 2-3DPG synthesis [53], but also that adipocytes release TNF-α and IL-6. Presumably, on return to normal air breathing, food intake rises, and insulin resistance persists until an ampler number of adipocytes release enough leptin which lowers bone formation and food intake without respiratory depression. In few words, with chronic exposure to intermittent, mildly increased CO2, body buffers loss sets a vicious cycle in which the more CO2 is inhaled and stored, the more food is eaten to raise PaCO2, foster ventilation, and save pH homeostasis.
With time, however, steady activation of the stress response leads to the loss of bone and muscle which, due to parallel abdominal fat accumulation, causes shallow, rapid breathing (not conscious tachypnea), turns up the set point for central feeding controllers, and induces overeating with its chronic pathological consequences, namely, MetS and osteoporosis.

Chronic exposure to CO2 at 0.5-3% inspired concentrations alters pH homeostasis and fosters body CO2 storage in humans [15,16, 17], as does increased atmospheric CO2 in the terrestrial biosphere. Increased CO2 stores in bone are present in osteoporosis, whose risks for osteopenia, and non-spine fractures have been shown to be significantly higher for subjects with higher percentage body fat, independent of body weight [25]. Fat accumulation and increased CO2 stores characterize also MetS which, despite lifestyle changes and the use of pharmacologic approaches to lower plasma cholesterol levels, continues to be, and it is expected to become the major cause of disability and death in the world by 2020 [108]. So far, it seems undeniable that pH homeostasis, the linkage between breathing and feeding via CO2 economy, discloses the stress of Global Warming on human health.

Chronic Respiratory Carbon Dioxide Toxicity: a serious unapprehended health risk of climate change
Quote
The earth’s atmosphere has already reached CO2 levels that are outside the range breathed by humans throughout their evolution. As well, in earlier pre-primate epochs, elevated atmospheric CO2 has been found to be a cause of mass extinction events (Knoll et al. 1996)

Despite significant documentation of health issues due to CO2 in indoor environments, there is minimal awareness in the community. For spacecraft and submarines there are practical considerations that influence the recommended safe levels. Initial safe limits for the International Space Station were partly decided by engineering requirements (Cronyn et al. 2012) and submarine limits were balanced by the ability to surface and renew air quality. It seems that there has been little concern about low-level toxicity of CO2 because we have always had the back-up of an ambient atmosphere with low levels of CO2.

As mentioned previously the body compensates for high levels of CO2, through a combination of increased breathing, blood pH buffering, kidney and bone adaptations depending on the length of continuous exposure, until we can resume breathing lower levels of CO2.

One author suggests that blood pH would be reduced to dangerous levels, if there were no physiological compensation, at CO2 levels as low as about 430 ppm (Robertson 2006) implying that compensation would occur at this level. Ambient conditions may already be dangerously close to CO2 levels that will induce continuous body compensation. Moreover, there is strong evidence that, with chronic activity, compensation mechanisms can produce serious health issues such as kidney calcification and bone loss.

It is conceivable that these problems might appear at much lower levels of CO2 if compensation persisted for a much longer periods, for example living a whole lifetime in an elevated CO2 atmosphere of a climate changed future. In the final paper of the US Navy CO2 research program, Schaefer (1982) indicated that this issue had “become the concern of the Department of Energy and other US government agencies” although it appears to have been largely forgotten (or classified) since.

If allowed to persist, problems such as kidney calcification could lead to renal failure. In the extreme case lifespans could become shorter than the time required to reach reproductive age. This could threaten the viability of human and animal species without interventions such as the creation of artificial living environments.

The human species is already impaired in indoor environments and this is likely to get worse as rising outdoor levels of CO2 contribute to increased indoor concentrations. Furthermore, the incidence and prevalence of human kidney calcification (i.e. stones) is increasing globally with the rate highest for males (Romero et al. 2010). Although this may not be related, it is possible that rising office levels of CO2 is a contributing cause. As well there is evidence that CO2 toxicity contributes to a range of serious health issues including cancer, neurological diseases and sleep disorders, and is being experienced by individuals at the current ambient levels which are now 40% higher than pre-industrial levels. It seems likely that CO2 toxicity related to human-induced climate change is already having an unrecognised impact on population health.

From the evidence presented here, there appears to be current health impacts of rising CO2 levels and a significant risk of serious health issues arising in the human population at some time in this century.

 This means that most humans could at this time be experiencing persistent body compensation for acidosis effects resulting in serious health problems. The risk for human and animal population health in the near-future is extremely high and should be communicated since global awareness of this issue may enable a change in CO2 emission activities.

High concentration of CO2 reduces man's intellectual abilities

https://www.skepticalscience.com/how-sapiens-in-the-world-of-high-co2-concentration.html


Changes in blood acidity level (pH coefficient) as  a function of CO2 concentration in the air we breathe (expressed in number of CO2 molecules per million - ppm). Increase of CO2 concentration in the atmosphere from 280 ppm in the preindustrial era to the current approximately 400 ppm reduces pH of our blood by 0.1 (which is equivalent to acidity increase by 30%).


The effect of CO2 concentration on peoples' decision abilities



Gradually, to the known effects of carbon dioxide emissions – like climate warming and ocean acidification – we will be forced to add impairment of our higher mental functions. Faced with the rising complex problems of our civilization, requiring the ability to analyze complex information, undertake initiatives and strategic planning - we place ourselves at a profound disadvantage, perhaps at a literally dysfunctional level.

Lowering IQ by 5 points, from the average of 100 to 95 – seemingly a small change – will cause a 40% rise in the number of people mentally handicapped and 60% decrease of the highly talented group. We need our intelligence and we should do our best to protect it.

If you want to supplement your Alkaline reserves, take a daily multivitamin with Calcium, Magnesium, and Potassium.

Drinking Alkaline water over an extended period can alkalize you digestive track creating serious health problems and provide another gateway for disease.

If you want to use it occasionally for hydration purposes, it's cheaper to just add baking soda to your tap water.

Spring water is slightly more alkaline that tap water in places without hard water, and unlikely to cause the problems you would incur with more alkalized water for daily use.

If you have hard water, your tap water is already alkalized.

And, of course, eat your vegetables.

But, the real problem we face is the continuous chronic compensation that happens within our bodies with the higher atmospheric CO2 levels.  The body's reaction to the acidosis.  Not just the exhaustion of alkaline reserves.

To remove CO2 from a room.

In a room with a humidifier, place some red devil lye (sodium hydroxide) in an open Tupperware.  That's it.  The lye will remove the CO2 from the air.  Do not use glass or metal containers as the Lye will react with it.

This is a simplified version of what was used on the Apollo spacecraft.

Remember to remove any plants from the room, as they will die.

Maybe it is better to just have lots of plants? I have 20+ orchids in my normal room of occupancy and tons of flowers (and a saltwater aquarium with reef flora and fauna to boot). I'm sure an extra fig tree or two would help even more but I think flowers and greenery are beneficial regardless. Why would you ever want to be in a room without flora or fauna when merely including them could help lower CO2 levels to well below background states?

Plants are much better, and have the added benefit of removing many indoor pollutants.

Air Pollution May Be Making Us Less Intelligent
https://phys.org/news/2018-12-air-pollution-intelligent.html

Quote
Not only is air pollution bad for our lungs and heart, it turns out it could actually be making us less intelligent, too. A recent study found that in elderly people living in China, long-term exposure to air pollution may hinder cognitive performance (things like our ability to pay attention, to recall past knowledge and generate new information) in verbal and maths tests. As people age, the link between air pollution and their mental decline becomes stronger. The study also found men and less educated people were especially at risk, though the reason why is currently unknown.

In animals, mice exposed to urban air pollution for four months showed reduced brain function and inflammatory responses in major brain regions. This meant the brain tissues changed in response to the harmful stimuli produced by the pollution.

Postmortem brain samples from people exposed to high levels of air pollution while living in Mexico City and Manchester, UK, displayed the typical signs of Alzheimer's disease. These included clumps of abnormal protein fragments (plaques) between nerve cells, inflammation, and an abundance of metal-rich nanoparticles (including iron, copper, nickel, platinum, and cobalt) in the brain.

The metal-rich nanoparticles found in these brain samples are similar to those found everywhere in urban air pollution, which form from burning oil and other fuel, and wear in engines and brakes. These toxic nanoparticles are often associated with other hazardous compounds, including polyaromatic hydrocarbons that occur naturally in fossil fuels, and can cause kidney and liver damage, and cancer.

Repeatedly inhaling nanoparticles found in air pollution may have a number of negative effects on the brain, including chronic inflammation of the brain's nerve cells. When we inhale air pollution, it may activate the brain's immune cells, the microglia. Breathing air pollution may constantly activate the killing response in immune cells, which can allow dangerous molecules, known as reactive oxygen species, to form more often. High levels of these molecules could cause cell damage and cell death.

The presence of iron found in air pollution may speed up this process. Iron-rich (magnetite) nanoparticles are directly associated with plaques in the brain. Magnetite nanoparticles can also increase the toxicity of the abnormal proteins found at the centre of the plaques. Postmortem analysis of brains from Alzheimer's and Parkinson's disease patients shows that microglial activation is common in these neurodegenerative diseases.

“People in social housing can’t put in an air-conditioning unit or install a ceiling fan. They would literally lie on the floor in the coolest part of the house and not move for hours," Crabtree says.

Blast-furnace ambient temperatures also turn people off physical exercise.

“If it’s just too hot and a walk to the bus stop is too far and the bus stop has no shade, people will stop walking. It's very much impacting how much people are walking or bicycling," Crabtree says.

Aside from the obvious health implications of less physical activity, researchers are also concerned about the "mental health effects of feeling trapped in your house and unable to do anything about it". ...

Built Shade will be a growth industry for all of our cities. I'm not talking about shaded bus shelters. I'm talking about massive block long shades in an attempt to address the urban heat island effect in a warming world.

Think this...

How Climate Change Is Affecting Residents' Health In Miami
Quote
For years, that discussion had been dominated by the impacts of rising sea levels. Now, the state's medical community is sounding the alarm about the health risks associated with rising temperatures. Whether it's a longer allergy season, air quality issues or mosquito-borne illnesses, heat is already making people sicker, they say, and the nearly 60 percent of Miami residents who live paycheck to paycheck could be the most in danger.

Well this is fairly terrifying

https://www.nytimes.com/2019/04/06/health/drug-resistant-candida-auris.html

So is the article linked at the end.
And this.. it is about the UK but perhaps the US of A is the market leader - America First!!

But warnings about the consequences of the overuse of antibiotics on humans and animals have been given for at least a decade. Until recently, Governments, Big Pharma and Agro-Industry have ignored these warnings. Your lot-fed beef and pork are stuffed full of antibiotics not a s treatment for illness but as a precaution against illness.

So it is now safer to have major surgery on your kitchen table than in the best of hospitals due to the risk of post-operational infections resistant to treatment.

Antimicrobial resistance poses ‘catastrophic threat’, says Chief Medical Officer
Antibiotic Action supports comments made by England’s  Chief Medical Officer, Professor Dame Sally Davies in the second volume of her annual report published today.   She issues stark warnings about the catastrophe we face if we do not immeidately address the threat of antimicrobial resistance.

The CMO said we could routinely see deaths from minor surgery within 20 years if new antibiotics are not discovered – highlighting the immediate and imminement threats that  antimicrobial resistance poses. She has called for politicians to act now, and for global action to be taken.

Her report mirrors calls made by Antibiotic Action– a UK led global initiative funded by BSAC – insisting the “discovery void” is addressed – few new antibiotics have been developed in the past two decades despite a new infectious disease being discovered every year for the past 30 years.  The report highlights how our amoury of antibiotics is nearly empty at a time when diseases are evolving and becoming more resistance to existing drugs.  In speaking of her report Professor Dame Sally Davies said:

“Antimicrobial resistance poses a catastrophic threat. If we don’t act now, any one of us could go into hospital in 20 years for minor surgery and die because of an ordinary infection that can’t be treated by antibiotics. And routine operations like hip replacements or organ transplants could be deadly because of the risk of infection.

“That’s why governments and organisations across the world, including the World Health Organization and G8, need to take this seriously.

“This is not just about government action. We need to encourage more innovation in the development of antibiotics – over the past two decades there has been a discovery void around antibiotics, meaning diseases have evolved faster than the drugs to treat them.

“In some areas, like cutting rates of drug resistant MRSA, the NHS is already making good progress so it’s important that we use that knowledge across the system and I hope my recommendations will prompt people to do that.”
