Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
Science has an important part to play in our everyday existence, and there is far too much neglect of science; but its intention is to supplement not to supplant the familiar outlook.
Arthur Eddington, Science and the Unseen World (1929).
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.
