There is mounting experimental evidence that lifetime exposure to increasing atmospheric CO2 levels can negatively impact the normal physiology of organisms. Directly assessing this in humans is very difficult. We analysed serum bicarbonate (HCO3−), calcium (Ca) and phosphorus (P) from 1999 to 2020 as indirect proxies for atmospheric CO2 exposure. Over this period, average bicarbonate levels in this population show an increasing trend which parallels rising atmospheric CO2 concentrations. Both. If these trends continue, blood bicarbonate values could be at the limit of the accepted healthy range in half a century, and Ca and P will be at the limit of their healthy ranges by the end of this century. This has the potential to cause a range of adverse health effects.

A microplastics and toxic chemicals expert says her family doesn't wear shoes at home. Microplastics from car tires and garbage, as well as street runoff, can be tracked indoors on shoes. The researcher thinks her kids' Japanese heritage helped them adopt the habit.
