Art is a diverse range of human activities in creating visual, auditory or performing artifacts (artworks), expressing the author's imaginative or technical skill, intended to be appreciated for their beauty or emotional power. In their most general form these activities include the production of works of art, the criticism of art, the study of the history of art, and the aesthetic dissemination of art.
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.
