- total energy entering each level is equal to the energy leaving that level as should be expected for a system in balance climate system if no changes over time equilibrium (temperature won’t change) if changes global temperature will change example: if the Earth absorbs more energy, temperature goes up 1) changes in output of the sun (sunspots) - solar output number of sunspots (solar radiation) varies over an 11 year cycle, and over centuries as well 2) change sin amount of solar radiation reaching the Earth - changes in Earth’s orbital characteristics changes amount and location of solar radiation 3) changes in solar radiation reflected from Earth (albedo) - major volcanic eruption, Mt. Tambora, Indonesia erupted 4/1815 worldwide temperature dropped .5 degrees C (1 degree F) caused “the year without summer” famine related to “agricultural havoc” 4) changes in level of greenhouse gases - main greenhouse gases: CO2 and methane (CH4)
