Forecast: climate change will lead to a 25-50% decline of thinking abilities

Being in a stuffy room has a bad effect on your thinking abilities. For example, by the end of a lecture in a badly ventilated room, students perceive information much worse. The reason is the increased concentration of carbon dioxide (CO2) in the air, which leads to oxygen deprivation of the brain. Scientists at the University of Colorado at Boulder (USA) have predicted an overall decline in human intelligence associated with climate change and increased indoor CO2 concentrations. 

The industrial revolution has led to an overall increase in the concentration of carbon dioxide in the air, especially in megapolises. This substance is contained in excess in exhaust fumes and industrial emissions. However, the concentration of carbon dioxide indoors is much higher than outdoors. This is due to the fact that the carbon dioxide contained in the air entering from the outdoors is added to the carbon dioxide emitted by humans at each exhalation. 

Today, the concentration of CO2 in the air is 250-450 ppm (the level depends on the degree of air pollution in a particular place). Colorado scientists have calculated that if the current rate of industrial pollution is maintained, by 2100 the concentration of carbon dioxide in the Earth's atmosphere will increase to 930-1300 ppm. Indoors, however, that concentration will increase to 1400 ppm. This will inevitably affect the brain function, because the most sensitive functions to the increase in carbon dioxide are the ability to plan and make decisions. Experts warn that when the concentration of CO2 in the air increases, the basic human ability to make decisions deteriorates by 25%. Complex strategic thinking will suffer the most - it will deteriorate by 50%.
