heating a house example-hotter indoor, greater rate at which house loses energy
Planet
-receives energy from source then loses energy to its environment
GG
-infrared, absorbing gases in atmosphere
-hard for earth to shed energy it gains from sun=Greenhouse Effect-keeps planet warm
EXAMPLE: Insulating Blanket:
-extra insulation, warmth
-causes new state of energy balance
-temp rises with increased insulation to ensure balace
NATURAL GE-earth would be chilly without it
*As concentration of atmospheric GG rises, so must the surface temp
Albedo-fraction of incident sunlight thats reflected
Evapotransporation-moves energy from surface to atmosphere in form of the latent heat of water vapor
*Today: Energy Imbalance
-increasing GG concentrations due to FF consumption
-more energy coming in than going out
-excess energy warming planet
-surface moderated b/c excess E goes to oceans-cause sea level to rise!
