Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
Fluctuations in atmospheric carbon dioxide (CO2) are a major component of the carbon cycle and the climate system. An EU-funded initiative investigated the past role of the Southern Ocean in influencing atmospheric CO2.
