Climate change graphicBy the year 2100, we may not be thinking too clearly.

Rising atmospheric carbon dioxide concentrations (CO2) might mean that people will be breathing indoor air with CO2听levels up to 1,400 parts per million by the end of this century, according to a CU 色吧亚洲-led study. That鈥檚 more than three times today鈥檚 outdoor CO2听levels and well beyond what humans have ever experienced. Air with such high CO2听concentrations may reduce our basic decision-making ability by 25 percent.

鈥淚t鈥檚 amazing how high CO2听gets in enclosed spaces,鈥 said , Fellow, associate professor at CU 色吧亚洲 and lead on the 2020听GeoHealth听study.听鈥淚t affects everybody鈥攆rom kids packed into classrooms to scientists to regular folks in their homes. It鈥檚 an indirect, overlooked impact of climate change.鈥
