The increasing level of carbon dioxide (CO₂) in the atmosphere may not only affect the climate—it could also be altering “human blood chemistry.”
A 20-year study tracking over 7,000 people found that bicarbonate levels in the blood have increased in line with rising CO₂. Meanwhile, calcium and phosphorus levels have declined, potentially affecting the body’s acid–base balance and forcing the kidneys to work harder to maintain stability.
Although these changes are not yet considered harmful, scientists warn that if the trend continues, blood chemistry levels could approach unhealthy limits within the next few decades.
This may be another sign that changes in our planet are gradually being reflected within the human body.
