But the concentration of carbon dioxide that stays in the atmosphere is only increasing by about half of that, and that's because half of the carbon we keep releasing into the atmosphere is currently being taken up by land and the seas through a process we know as carbon sequestration.
En canvi, la concentració del CO₂ que es queda en l’atmosfera està augmentant solament la meitat, i la raó és que la meitat del carboni que seguim alliberant està sent absorbida per la terra i els mars en un procés anomenat ‘captura de CO₂’.
