- Anthropogenic activities are increasing atmospheric CO2 levels, which may negatively impact organisms, including humans.
- Using NHANES data (1999-2020), serum bicarbonate (HCO3-) levels increased while calcium and phosphorus decreased, correlating with rising atmospheric CO2.
- If trends continue, bicarbonate could reach the upper healthy limit by around 2076, and calcium and phosphorus could reach lower limits by around 2099 and 2085 respectively.
- Elevated CO2 can cause hypercapnia, acidosis, and compensatory mechanisms such as increased bicarbonate retention and bone mineral release, potentially leading to health risks.
- Potential adverse health effects from long-term CO2 exposure include oxidative stress, tissue calcification, cognitive impairment, anxiety, and increased risk of chronic diseases.
- Studies suggest even moderate indoor CO2 levels (e.g., 1,000-3,000 ppm) can harm health, and prolonged exposure may lead to physiological changes affecting bone, kidney, and brain function.
- The findings highlight a potential existential threat from atmospheric CO2 overload, urging immediate reductions in emissions to safeguard public health.
