Rising levels of carbon dioxide (CO2) in the atmosphere are causing measurable changes in human blood chemistry, according to a new study. Researchers have found that blood bicarbonate levels have increased by about 7% since 1999, while calcium and phosphorus levels have decreased.

The findings suggest that as atmospheric CO2 concentrations continue to rise due to human activities, there could be significant impacts on human health. This shift in blood chemistry is closely correlated with the increase in atmospheric CO2 over the past two decades.

These changes may affect overall bodily functions and potentially lead to long-term health issues. Further research is needed to understand the full implications of these shifts on public health and how they might be mitigated.
