Document Summary
Energy transfer mechanisms: radiation light and heat being transferred from each human being, the sun, sensible heat -warmth of air and water, latent heat water vapour. Global radiation balance: absorbed light = emitted infrared radiation: problem: get more sunlight at the equator and we have to move it towards the poles. Global ocean circulation drive by one location (north atlantic: north atlantic deep water formation because the water freezes. It has so much salt in the water that it sinks to the bottom when it freezes: feedback. Response feedback: the effect of the outcome of an action on the rate of the action. + the outcome of an action accelerates: lag response. Messages: global climate is sensitive and responding to human activities, environmental responses. Influences on global climate: solar variation (shortwave, planetary reflectivity (albedo) Cloud, snow, ice, desert, forest, water: atmospheric composition. Carbon dioxide: ocean salinity and connectivity.
