https://www.theguardian.com/commentisfree/2018/sep/24/air-pollution-cognitive-improvement-environmentbusiness as usual, which is the track we’re on – predicts atmospheric CO2 concentration of 1,000ppm by 2100. At 1,000ppm, human cognitive ability drops by 21%.
Even if we meet the most stringent targets set at the Paris agreements in 2015, 2100 will bring atmospheric CO2 levels of 660ppm – with around a 15% decrease in average brainpower.
https://thinkprogress.org/exclusive-elevated-co2-levels-directly-affect-human-cognition-new-harvard-study-shows-2748e7378941/For most of human evolution and modern history, CO2 levels in the air were in a fairly narrow and low range of 180 to 280 parts per million. ...
But in recent decades, outdoor CO2 levels have risen sharply, to a global average of 400 ppm. Moreover, measured outdoor CO2 levels in major cities from Phoenix to Rome can be many tens of ppm higher—up to 100 ppm or more—than the global average
“In surveys of elementary school classrooms in California and Texas, average CO2 concentrations were above 1,000 ppm, a substantial proportion exceeded 2,000 ppm, and in 21% of Texas classrooms peak CO2 concentration exceeded 3,000 ppm.”
We are rising at a rate of 2+ ppm a year, a rate that is accelerating.
“The exposure-response between CO2 and cognitive function is approximately linear across the concentrations used in this study.”
