Infertility, heart failure and kidney disease: How does climate change impact the human body?

By Lauren Crosby Medlicott  •  Updated: 18/06/2022 – 09:43

Here are just 10 ways we’re already seeing climate change impacting the human body – some you may expect, while some are more discreet.

10. Heat stress on the heart

Record-breaking temperatures are going to become more frequent as the global temperature either reaches or exceeds 1.5 degrees Celsius of warming over the next 20 years. More and more, we are hearing of deadly heatwaves and wildfires sweeping across hot, dry expanses of land. Extreme temperatures have been found to kill 5 million people each year.

Those who manage to live will be forced to deal with the consequences of excessively high temperatures in their everyday lives.

When temperatures are higher, so is cardiac demand. The heart must pump harder and faster to redistribute and increase blood flow to the skin to cool the body. People with heart diseases, whose hearts are weakened, are particularly at risk of heart failure and heat stroke in hot weather as their organs struggle to function properly with the added stress.

9. Sleep disruption

A 2022 study led by Kelton Minor, of the University of Copenhagen’s Centre for Social Data Science, finds that rising temperatures driven by climate change are significantly decreasing the amount of sleep people all around the world are having.

8. Respiratory Issues

Ozone is a gas naturally found in the Earth’s upper atmosphere, providing a shield from the sun’s ultraviolet rays. Ground level ozone, which is dangerous for our health, is produced when pollutants emitted by manmade sources like cars or chemical plants react in the presence of sunlight.

7. Kidney damage

Dehydration from heat exposure can damage the kidneys, which depend on water to help remove waste from our blood in the form of urine.

6. Aggravated allergies

With rising CO2 levels, which have increased by 9 per cent since 2005 and by 31 per cent since 1950, the amount of pollen increases as a consequence of higher rates of photosynthesis.

5. Damage to heart circulation

When air pollutants travel into your bloodstream through your lungs and into your heart, the risk of developing heart and circulatory diseases increases as blood vessels narrow and harden.

4. Infertility

One of the lesser known effects of air pollution is being studied by Dr Gareth Nye, Lecturer of anatomy and physiology at the University of Chester, UK, who researches air pollution’s impact on fertility.

“A paper looking at 18,000 couples in China found that those living with moderately higher levels of small-particle pollution had a 20 per cent greater risk of infertility,” Nye tells Euronews Green.

3. Malnutrition

As temperatures increase, so do food shortages. This is seen most clearly in communities whose livelihoods depend on agriculture and fishing, such as in the Global South.

2. Mental health

Physical health isn’t the only way we’re impacted by climate change though. Following global disasters like wildfires, floods, or hurricanes, mental health problems are only getting worse.

1. Microplastics found in our bodies

It isn’t just climate change that harms our health, it’s the disregard for the wellness of our planet, seen clearly in our overuse of (and reliance on) plastics.

Read more: https://www.euronews.com/green/2022/06/18/infertility-heart-failure-and-kidney-disease-how-does-climate-change-impact-the-human-body

What I find most entertaining about this absurd list, is the author couldn’t put 10 points together of problems caused by climate change. Point 8 (pollution), point 7 (not drinking enough water), 5 (pollution), 4 (pollution), and 1 (microplastics / pollution) have nothing to do with climate change.

Point 6 (pollen allergies), contradicts point 3 (malnutrition). You can’t have it both ways. Either plants are killed off by climate change, leading to malnutrition but less pollen, or plants grow more vigorously, causing more allergies but less malnutrition. OK, they tried to have it both ways – but the claim that climate driven greater food abundance was causing malnutrition was too silly even for a climate claim.

Point 2, there is no evidence more people are being harmed by global disasters. Global death rate from natural disasters has plummeted over the last century.

Points 10 & 9 – the body does work harder in a heatwave, that much is true. But cold is a far deadlier killer than heat, even in warm countries like India. Humans are hairless tropical apes, we evolved in the hottest climate zones on the planet. Outside the extreme tropics where we evolved, even in warm countries like India, we need clothes to stay warm.

One day historians will look back on our age, and marvel that so many people convinced themselves they were living in a time of disaster and catastrophe, when by every reasonable metric our world is healthier and wealthier than any previous age in human history.

Many areas within Australia experience very high temperatures day and night in summer and other months of the year. I have driven to most of those areas at least once and some several times over the past twenty years and to some areas from time to time in decades earlier.

I survived, drink lots of water to stay hydrated, avoid long periods exposed to the direct sunshine, adapt.

Exactly. Even the author admits that it’s a weak heart or heart disease that causes heart attacks and strokes – there is no evidence that heat alone increases the risk of these issues occurring. I would say that it is the lack of sunlight and thus vitamin D that has a far higher correlation with heart failure, along with factors such as a sedentary lifestyle – increased activity strengthens and tones the heart, like any muscle tissue.

In the US, ozone has been a recognized problem in Cities in Southern California and has been declining during the last 20 years because of observing stricter air concentration levels.
Here is a link to other areas with higher air concentrations than in the US. If you search Google for air concentration of ozone in cities/countries around the world you will find many more links than the one listed below.

I think it’s more to do with trying to hide vaccine side effects myself. So far this year, climate change, high atmospheric aerosols, flipping of the magnetic field, solar flares, chemtrails and tropical storms have been to blame for heart attacks, blood clots, strokes, Sudden Adult Death Syndrome, immune diseases, etc etc. Nobody’s blaming the vaccine but strangely none of these issues are popping up in unvaccinated people.

I wonder from which magical hat does their data come out.

Actually we are far from any such trend according to UAH global temperatures records :

Despite a steady increase in atmospheric CO2 concentration since decades :

The actual trend is about +0.1°C / decade and it’s decreasing :

What radical sort of change in the next 20 years could sweep away those observations ?

The narrative is becoming absurd. You can’t make this stuff up, but we are having it shoved down our throats like we are dung beetles.
On another note, it is exactly 3 years ago , to the hour that Andy Pitman made the accidental truth bomb that there is no link between drought and climate change.
For those that have forgotten the incident, it appears that Andy was actually correct, what with all the rain we have been having. To recap-
The question was not some evil question, it was a benign question on native grasses. I almost fell off my chair reaching for my notepad. A rather excited SMS was sent to Senator Roberts informing him about it on the train home. It was a very long wait for the podcast to become available, which was duly recorded on my phone immediately. The transcript was produced shortly thereafter.

IPCC AR4 Chapter ten Page 750 Says:

Mean Precipitation
For a future warmer climate, the current generation of models indicates that precipitation generally increases in the areas of regional tropical precipitation maxima (such as the monsoon regimes) and over the tropical Pacific in particular, with general decreases in the subtropics, and increases at high latitudes as a consequence of a general intensification of the global hydrological cycle. Globally averaged mean water vapour, evaporation and precipitation are projected to increase.

Not a recipe for drought.

Then there’s NOAA’s Climate at a Glance that shows us the precipitation for the USA-48 since 1895: LINK

I think so. The data dumps from Pfizer reveal lots of side effects including shingles and chicken pox which are very similar to monkey pox, so similar correct diagnosis is extremely difficult. Monkey pox is rare outside of Africa yet suddenly appears in ten or more countries at the same time. Coincidence yeah right. The WHO are up to something I think on the 23 June to decide if its a matter of international concern. They will announce their decision on June 30th (hope my dates are correct) No doubt our politicians will follow what ever economy crushing guidelines they are given. There are quite a few good articles on this on The Expose if anyone wants to learn more.

No, the spread is due to unprotected promiscuous male homosexual sex.

But not to worry, like HIV, we taxpayers will shell out whatever it takes to help these individuals deal with their self induced problems.

I should be dead. And so should a dozen of my colleagues. We used to leave Oz in winter, 10 to 15 degC, and go to work in western Oman 50 to 55 degC. Surely one of us should be dead by now, surely, from heat stress. I must admit I didn’t sleep well but that’s cos I was working so much. I notice the Lancet study that covered the 5,000,000 deaths, did not address the middle east, the hottest region on earth. How ’bout that!

June 19, 2022 3:53 am

Here in Michigan a major cause of death is men shoveling snow and getting heart attacks. Or so I told the wife Last winter we had the least snow, by far, since I moved here in 1977. The wife only had to shovel our 100 foot driveway three times over the winter. (PS: She likes to shovel — considers it good exercise — she could hire a snow plowing service any time she wants too.) I watch out the window, amazed that anyone over age 70 could do such hard work. Global warming has made the job easier than ever = fewer heart attacks.

I tend to agree that climate change politics can cause stress and anxiety, and they can lead to heart failure.

It’s the deception, the hoax, the cunning manipulation including creative accounting of computer modelling to produce an exaggerated warming trend, the scare tactics calling natural climate and weather events a climate emergency and claiming that there is a tipping point of no return not far ahead, but the goal posts are moved as that point is reached with event.

Worst of all that Marxists and fellow travellers of the far left plot to destroy the free market system they call capitalism, the economic system that created a better world generally in terms of advances for humanity generally, and economic prosperity.

I would love to read an account of all this in about 100 years. I bet the skeptics will be vindicated.

The official position is that if we keep adding more CO2 to the atmosphere, the temperatures will reach 1.5C or more above the average they use.

The highest temperature in the 21st Century was in 2016, which NOAA claims was 1.1C above their average. Since 2016, the temperatures have cooled by about 0.5C, so currently, we are a long way from reaching 1.5C above the average.
