- 1Sefan Boltzman EquationW/m^2 = sigma x T^4(temp in Kelvin)
- 2look on powerpoint for energry balance models-242C if no sun
5C if no greenhouse gases(pretty sure said 0 before so need to ask)
no GHG and reflection = -18C/0F - 3Energy balance model 1no sun: earth's surface 32K
- 4RCPRepresentative Concentration pathways RCP2.6(low emission) scenario
RCP8.5(high emission) scenario - 5Energy balance model 2no albedo, no GHG: 5C
- 6Energy balance model 3albedo, no GHG: -18C/-.4F
- 7Energy balance model 4adds GHG from 3: 30C
- 8steps to develop climate model1. develop equations
2. solve equations on comp by grid segments(latitude and longitude)
3. build and implement conceptual models
4. compare predictions to observations
5. adjust components to bring closer to observations - 9FAR, SAR, TAR, and AR4FAR(First assessment report)
SAR(Second assessment report)
TAR(Third assessment report)
AR4(forth assessment repo - 10Atmospheric-OceanGeneral Circulation modelsstudy dynamics of atmospheric ocean, land, and sea ice on climate. older used when biogeochemical feedbacks not critical
- 11Earth System modelsused to study different biogeochemical cyles(i.e. carbon, sulfur, and ozone cycle) most state of the art
- 12Earth System Models of Intermediate Complexitysimplified version of Earth System models used to understand climate feedback over time(scale 1000s of years)
- 13CMIP5(Climate Model Intercomparison Project)over 100 climate models. modeling groups run same experiment with their models and compare results
- 14multimodel ensembleusing many different models to estimate forecast, specifically used a lot with hurricanes, which is why their are predictions of different ways the hurricane might go
- 15examples of CMIP5 experimentspast 1.5 centuries
quadruple CO2 abruptly
preindustrial conditions
hindsight without an event
decadal forecast with a climate changing event in a year - 16natural inputsvolcanoes and sun
- 17anthropogenic inputsgreenhouse gases and aerosols
- 18processing producing variabilitysolar(sunspots), volcanoes, el nino, greenhouse gases
- 19Socio-Economic scenarios(SRES, SRES A2, A1B, B1) emissions due to socio-economic development, energy production and use, technology, forestry, agriculture, and land use
- 20any RCP models predict drop in temperatures by 2100?RCP2.6
- 21predicted concentrations of CO2 depending on RCP in 2100RCP8.5: 1000
RCP6: ~600
RCP4.5: ~520
RCP2.6: ~400 - 22where would temperature changes be more extremetowards the poles
