A long-term monitoring mission by NASA yields valuable insights into the carbon cycle and how it may be altered by a changing climate.

Two recent international studies are poised to change the way scientists view the crucial relationship between Earth’s climate and the carbon cycle. These reports explore the global photosynthesis and respiration rates—the planet’s deep “breaths” of carbon dioxide, in and out—and researchers say that the new findings will be used to update and improve upon traditional models that couple together climate and carbon.
