Rising CO2 emissions may directly harm our ability to think: Researchers

New York: Researchers have found that rising atmospheric carbon dioxide (CO2) concentrations will cause urban and indoor levels of the gas to increase, which may significantly reduce our basic decision-making ability and complex strategic thinking. Earlier research has shown that elevated CO2 levels can increase sleepiness and anxiety, and impair cognitive function.

The study, revealed that by the end of the century, people could be exposed to indoor CO2 levels up to 1400 parts per million - more than three times today’s outdoor levels, and well beyond what humans have ever experienced.

“It affects everybody, from little kids packed into classrooms to scientists, business people and decision-makers to regular folks in their houses and apartments,” study lead author Kris Karnauskas from the University of Colorado Boulder in the US.

According to the researchers, CO2 can also build up in poorly ventilated spaces over long periods of time, such as overnight while sleeping in bedrooms. (IANS)
