Scientists detect a surprising shift in human blood as CO2 rises
A study analyzing 20 years of U.S. health data suggests that rising atmospheric CO2 levels are causing measurable shifts in human blood chemistry, specifically increasing bicarbonate levels. Researchers warn that these changes could impact long-term health, particularly for younger generations.
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 CO 2 , raising concerns that an important blood marker could approach the upper end of its healthy range within the next several decades.
