Document Summary

Radiation in the atmosphere: main energy light, aerosols, heat and ocean sink, most energy incoming is shortwave and absorbed, a lot of energy emitted as heat into the atmosphere, most energy is also reflected back to the earth greenhouse effect, light is reflected by the clouds and aerosols (particles of dust that reflect sunlight, evapotranspiration energy is given out due to water. Co2 and temperature: water vapor changes in the atmosphere depending on temperature, co2 created from running and respiration, summer time in northern hemisphere has a lot more production, a lot less production in the southern hemisphere summer, this gives us fluctuations in the co2 concentrations, direct measurement is possible for current trends instead of proxies but does not show causation, seasonality over warming trend northern hemisphere has greater land mass and vegetation therefore you get more of an influx in carbon during summer times.
