Aeolus designated by zeus to look after the four winds. Within greek mythology, aeolus was designated by zeus to look after four winds. Boreas is a chilly north wind that originates in the north and blows towards the south. Modifies the environment to best suit itself. Mars and venus are in a static equilibrium with high levels of carbon dioxide and methane. Early sun produced 30% less energy (archean) arly earth with high levels of methane and carbon. Dioxide had a strong greenhouse effect which lead to conditions warm enough for life year solar output increased and earth was becoming too warm, the switch to aerobic life, reduced the greenhouse gases (co2ch4) and cooled the planet. We now have considerably lower levels of co2 in the atmosphere than the early earth. Gaia hypothesis postulates that the atmospheric constituents have been controlled by life to optimize conditions for life (biologic control)
