Scientists Prove that CO2 May Adversely Impact the Cognitive Abilities

Researchers of University of Colorado Boulder in cooperation with Colorado School of Public Health and the University of Pennsylvania have discovered that higher CO2 levels in the future may adversely impact the cognitive abilities of students in classrooms.

According to the phys.org report, researchers published a paper describing the findings on the EarthArXiv preprint server and explained that the pollution inside a classroom (including CO2) can lead to cognitive problems.

Researchers wondered what happens when the fresh air has high levels of CO2. To find out, they created a model with two outcomes. In the first outcome, humans reduce the amount of CO2 pumped into the atmosphere. In the second, they do not.

They report that in the first scenario, students were still exposed to so much CO2 that their cognitive abilities were decreased by 25 percent by 2100. In the second, which was the business-as-usual scenario, the students were exposed to so much CO2 when the windows were opened that they experienced a 50 percent reduction in cognitive ability.

The researchers note that theirs is the first study to look at the impact on people who breathe higher-than-normal levels of CO2 on a regular basis. They further note that this problem could be averted by ending CO2 emissions.
