Document Summary

Water = reason why we are warm (water vapor and clouds) How much energy is going to be absorbed by a certain greenhouse gas. Energy molecules receives molecule vibrates and rotates energy gets emitted back out. Some energy radiates back down = greenhouse gas effect. Will not be steady state and will get warmer or colder. Need to locate arrows and their direction. Outgoing part of earth stuck in middle atmosphere. Albedo (2/3 is cloud) big radiation impact. Hard to quantify their effect/variation is type/cover. Where clouds are type of weather were going to have. High level clouds reflect more of sun radiation.
