Climate forcing	something that changes earth's energy budget(input or output) can be natural(i.e. volcanic) or caused by humans changes global temperature
radiative forcing	change in net, downward minus upward radiation at the top of atmos, changed by concentration of Greenhouse gases, change occurred relative to 1750(indust revo)
climate sensitivity	magnitude of temp response
sun solar output changes(why)	sunspots
sunspots	11 year cycle changes by about .1% more solar radiaton
albedo	reflection: clouds, glaciers, deserts, vegetation, aerosols(fog dust steam smoke etc.)
aerosols	airborne solids or liquid particles size <10microns(basically atoms-dust) suspended in the atmosphere fog, dust, steam, smoke, air pollutants, soot
albedo #s	snow clouds(>50%), soil plants(49-11%, water <10%
sources of aerosol	dust, soot, fires, manufacturing
ozone	reflects UV light in stratosphere if in troposphere toxic to plants and animals
most effective climate forcing	Greenhouse gas(warming) aerosols(cooling)
El Nino	reversal of winds near equator and warms up area around south america results in warmer winter in US and australia and some other stuff around the world
radiative forcing values	CO2(~2) Methane, N2O(~1) ozone(~.5) aerosol(~-1)
climate sensitivity parameter	0.4 change in temp = radiative forcing * .4
feedback loops	positive feedback amplifies negative decreases, look at water vapor feedback loop
