Rising carbon dioxide in the atmosphere may be leaving a measurable imprint inside the human body. Researchers analyzing more than two decades of U.S. health data found that blood bicarbonate levels have climbed about 7% since 1999, while calcium and phosphorus have declined—changes that closely track increasing atmospheric CO2.

On va vivre moins longtemps.

Rising levels of carbon dioxide in the atmosphere may already be influencing human biology. New research has identified long-term changes in blood chemistry that appear to track rising atmospheric CO2, raising concerns that an important blood marker could approach the upper end of its healthy range within the next several decades

“If current trends continue, modeling indicates average bicarbonate levels could approach the upper limit of today’s accepted healthy range within 50 years,” A/Prof Larcombe said

“Calcium and phosphorus levels could also reach the lower end of their healthy ranges later this century.”
