The occasionally acrimonious debate about the planet's climate has been missing a key component: accurate measurements of how much carbon dioxide is in the air and how it is being recycled by Earth.

Since the start of the industrial age, the concentration of carbon dioxide in earth's atmosphere has increased by about 25%- from 280 parts per million to over 370 parts per million. As concerns over climate change increase, scientists are being asked difficult questions about the extend to which carbon is being put into, and taken out of , the atmosphere. Precise answers to questions like these are necessary to reliably forecast changes in earth's climate. But massive gaps remain in our understanding of what happens to carbon dioxide after hit has been produced.
