Study Finds Elevated CO2 in Human Blood, Warning of Toxic Atmosphere Within 50 Years

A peer‑reviewed study reports elevated carbon dioxide levels in human blood samples. Researchers measured CO2 concentrations that exceed normal physiological ranges. The results suggest atmospheric CO2 could become toxic within the next 50 years. The analysis used blood samples collected from multiple demographic groups. Rising global emissions are identified as the primary driver of the increase. The authors warn that such exposure may pose serious health risks. They call for urgent mitigation strategies to reduce carbon output. The study underscores the need for policy action to protect public health.
