Researchers analyzing United States health records from 1999 onward have documented a measurable change in human blood composition. Blood bicarbonate concentrations have risen approximately seven percent since monitoring began.

Calcium and phosphorus levels have declined alongside the documented rise in atmospheric carbon dioxide. The chemical shifts correspond with the two-decade increase in carbon dioxide.
