A first-ever study of air trapped in the deep snowpack of Greenland shows that atmospheric levels of carbon monoxide (CO) in the 1950s were actually slightly higher than what we have today, not lower as has been predicted by computer models. And improved combustion technology has been linked to the lower CO levels.
