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.
Mas a concentração de dióxido de carbono que permanece na atmosfera tem vindo a aumentar apenas metade desse valor, e isto porque metade do carbono que libertamos para a atmosfera vai sendo absorvido pela terra e pelos oceanos através de um processo denominado retenção de carbono.
