A new study suggests rising carbon-dioxide levels may be slowly changing human blood chemistry and could impact long term ...

Humans evolved in an atmosphere containing roughly 200–300 parts per million (ppm) of carbon dioxide (CO₂). Today, that ...

Study Suggests Human Blood Could Be Pushed Past Its Healthy Limits Within 50 Years In A Nutshell A new analysis of U.S. blood test data from 1999 to 2020 found that average bicarbonate levels in the ...

Researchers from The Kids Research Institute Australia and Curtin University have found that rising atmospheric carbon dioxide is leaving a measurable trace in human blood, and the shift may be ...

From the air to our blood ...

The main driver of climate change is carbon dioxide. So the fact that it is rising at rates unseen in the instrumental record — and likely much longer than that — is cause for alarm. Yet here we are.

*Refers to the latest 2 years of stltoday.com stories. Cancel anytime. Brian Geurin's letter "Incorrect to call carbon dioxide a pollutant" (Aug. 26) misses the point. Does it matter whether carbon ...

The levels of the crucial heat-trapping gases in the atmosphere reached historic highs last year, growing at near-record fast paces, according to the U.S. National Oceanic and Atmospheric ...

Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue.
