First-time measurements in Greenland snowpack show a drop in atmospheric co since 1950s
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. This is a surprise because current ...
