- Anthropogenic activities are increasing atmospheric CO2 levels, which may negatively impact human physiology.
- Analysis of NHANES data (1999-2020) shows rising serum bicarbonate (HCO3−) levels, paralleling increasing CO2 concentrations.
- Calcium (Ca) and phosphorus (P) levels in blood have decreased over the same period.
- If trends continue, HCO3− could reach unhealthy levels by 2076, and Ca/P by the end of the century.
- Elevated CO2 exposure may lead to health risks such as metabolic acidosis, oxidative stress, and cognitive impairment.
- CO2 retention in the body could cause kidney calcification, bone resorption, and other systemic effects.
- Long-term exposure to elevated CO2 may disrupt protein function, calcium-phosphate balance, and brain activity.
- Reducing anthropogenic CO2 emissions is urgently needed to mitigate potential health risks.
