Not only does it affect the climate, and rising carbon dioxide concentrations make people stupid.

December 24 (Xinhua) — Humans may become increasingly dull as the concentration of carbon dioxide (CO2) in the Earth’s atmosphere increases, according to a new study by the University of Colorado. Scientists have long reportedly noticed that students’ grades decline when they study in unventilated rooms. There is now a wealth of evidence that human cognitive function is associated with the amount of carbon dioxide inhaled into the air. Overall, the impact is negative and obvious.

Not only does it affect the climate, and rising carbon dioxide concentrations make people stupid.

From 1813 to 2018, the amount of carbon dioxide in the Earth’s atmosphere increased from 280 ppm to 409 ppm (ppm is a unit of component content measurement, 1 ppm means 1 mg per kilogram).

Not only does it affect the climate, and rising carbon dioxide concentrations make people stupid.

Chris Kanoskas, a professor of marine science at the University of Colorado, says that if co2 concentrations in the air continue to rise at a high rate and indoor CO2 continues to rise, humans will be noticeably dull by 2100.

Not only does it affect the climate, and rising carbon dioxide concentrations make people stupid.

In 2016, researchers at Harvard University found that when indoor CO2 reached 945 ppm, human cognitive function decreased by about 15 percent, and by 50 percent when indoor CO2 reached 1400 ppm.

According to Canoskas, co2 concentrations can reach 1000 ppm in an impermeable bedroom in just one night.
