More atmospheric CO2 could reduce cognitive ability, especially in children

This is something I have thought about. Seems pretty obvious.

New research from the University of Colorado Boulder, the Colorado School of Public Health, and the University of Pennsylvania found that higher levels of atmospheric CO2 in the future could lead to cognitive issues.

A new study found that higher concentrations of atmospheric CO2 could negatively impact our cognitive abilities — especially among children in the classroom. The findings were presented at this year’s American Geophysical Union’s Fall Meeting.

However, what happens when the air outside also shows higher-than-usual CO2 levels? In an effort to find out, the team used a computer model and looked at two scenarios: one in which we successfully reduce the amount of CO2 we emit into the atmosphere, and one in which we don’t (a business-as-usual scenario). They then analyzed what effects each situation would have on a classroom of children.

In the first scenario, they explain that by 2100 students will be exposed to enough CO2 gas that, judging from the results of previous studies, they would experience a 25% decline in cognitive abilities. Under the second scenario, however, they report that students could experience a whopping 50% decline in cognitive ability.
