Flashcards do conjunto (15)
- 1Climate forcingsomething that changes earth's energy budget(input or output)
can be natural(i.e. volcanic) or caused by humans
changes global temperature - 2radiative forcingchange in net, downward minus upward radiation at the top of atmos, changed by concentration of Greenhouse gases, change occurred relative to 1750(indust revo)
- 3climate sensitivitymagnitude of temp response
- 4sun solar output changes(why)sunspots
- 5sunspots11 year cycle changes by about .1%
more solar radiaton - 6albedoreflection: clouds, glaciers, deserts, vegetation, aerosols(fog dust steam smoke etc.)
- 7aerosolsairborne solids or liquid particles size <10microns(basically atoms-dust) suspended in the atmosphere
fog, dust, steam, smoke, air pollutants, soot - 8albedo #ssnow clouds(>50%), soil plants(49-11%, water <10%
- 9sources of aerosoldust, soot, fires, manufacturing
- 10ozonereflects UV light in stratosphere if in troposphere toxic to plants and animals
- 11most effective climate foringGreenhouse gas(warming) aerosols(cooling)
- 12El Ninoreversal 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
- 13rediative forcingCO2(~2)
Methane, N2O(~1)
ozone(~.5)
aerosol(~-1) - 14climate sensitivity parameter0.4
change in temp = radiative forcing * .4 - 15feedback loopspositive feedback amplifies negative decreases, look at water vapor feedback loop
