How Climate Change Is Messing With Your Blood
Rising carbon dioxide levels in the atmosphere do a lot of damage—heat waves, droughts, wildfires, superstorms. Now it appears there’s another knock-on effect that had never before been measured. According to a new study in the journal Air Quality, Atmosphere and Health, the changing chemistry of the atmosphere could be leading to changing chemistry in our blood—with potentially dangerous effects.
If CO2 is indeed messing with our blood, it’s no wonder. During the early rise of Homo sapiens, carbon dioxide levels in the atmosphere measured a consistent 280 parts per million (ppm). Those conditions prevailed until roughly the middle of the 18th century when the Industrial Revolution began pouring greenhouse gasses into the air from factory smokestacks. By 1900, CO2 levels had risen to nearly 300 ppm; by 1980, that figure had jumped to nearly 330 ppm. Since then the numbers have exploded, standing at 425 ppm today.
Because we had direct measurements for all those millions of years, right?
That’s very bad news for the health of the planet—and equally bad for the health of our bodies. Every breath we take—indoors or out—draws in more carbon dioxide than our bodies were originally adapted to cope with. To determine just what the impact of this is, environmental geoscientist Phil Bierwirth, of Australian National University in Canberra, and environmental health scientist Alexander Larcombe, of the University of Western Australia, took advantage of a 21-year survey—from 1999 to 2020—conducted by the U.S. National Health and Nutrition Examination Survey (NHANES), during which government investigators sampled the blood of 7,000 subjects every other year to see how the body responded to all manner of environmental pollutants.
How do we know that our bodies were originally adapted to cope with that? Do Warmists no longer believe in Darwinism? Do they realize humans breath out about 400pm of CO2 with each exhale?
What’s more, at moment, our bodies are are doing a good job of adjusting to the level of CO2 that does exist in the armosphere—even if just barely—since most people are not experiencing the warning symptoms Larcombe describes. But the famed CO2 hockey stick—the y-axis graph that shows greenhouse gasses and global temperatures steadily rising—is pushing us ever further into the danger zone.
Sigh. This is all based on faulty science. Missing data. Computer models. Wishful thinking. Cult dogma. We really have no direct measurements even 200 years ago. And yet the cult is so worried that the vast majority make almost no changes in their lives to reduce their own carbon footprint.

Of course, the Homo sapien species is likely only about 0.25 million years old!!
Deniers of Science like “Professor” Teach demand absolute proof of everything all the time – except to support “their” claims, LOFL. He questions the best available evidence on CO2 levels in this instance but accepts that CO2 was higher 10s of millions of years ago!

The best estimates indicate humans evolved in an atmosphere of 200 – 300 ppm CO2. Humans and other animals are now adapting to 425 ppm CO2 (and higher). The study that Teach mocks found that from 1999 to 2020 humans adapted with a 7% increase in blood bicarbonate (HCO3-) proportional to the increase in atmospheric CO2, and with similar DECREASES in serum calcium and phosphorus. Human RBCs convert blood CO2 to HCO3- which converts to CO2 in lung capillaries and partitions into alveoli.
Teach typed: “Do (slur) no longer believe in Darwinism?”
Does he mean evolution? Does he NOT understand the evidence supporting evolution? Christianism has had to rapidly evolve this past century to accept the overwhelming evidence supporting evolution. They’ve had to accept that our Earth is billions of years old. That dinosaurs existed 100s of millions of years before Homo’s.
We get it. “Professor” Teach Denies that CO2 is causing the Earth to warm, so has to Deny that the increased CO2 has any effect on humans. His Denial becomes more strident as evidence accumulates.
Teach typed: “Do they realize humans breath out about 400pm of CO2 with each exhale?”
Not sure what Teach means. The concentration of CO2 in expired air is about 40,000 ppm!! The total amount of CO2 expired by a H. sapiens is about 300 to 1000 g/day depending on activity level. (We burn more glucose with exercise, i.e., C6H12O6 + O2 –> CO2)
“Professor” Teach concludes: “Sigh. This is all based on faulty science. Missing data. Computer models. Wishful thinking. Cult dogma.”
He would be more persuasive if he pointed out the “faulty science. Missing data. Computer models. Wishful thinking. Cult dogma” in the scientific paper. But Teach the MAGAt doesn’t want a discussion or to understand anything. Sigh.
