ES 106 Thinking In Systems Diagrams Powerpoint Toolkit for System Maps Copy and Paste Items you need and move things around in order to develop your systems thinking map skills I ve made these Slides 8 x 11 so that they should print out just fine Be aware of getting your maps too close to the margins You can also see examples of how one might develop system maps from what we ve worked on in section As you do this for your paper keep in mind that you only need to map one system stock per article assigned in the paper and that you don t have to have every single feedback since feedbacks abound However you should consider what the news articles discuss in terms of feedback or add some of your own that you think are particularly relevant Toolkit Stocks and Flows Inflow Stock Box Outflow Inflow Inflow Arrow Glacier Mass Outflow Arrow Yellow circles when you click on a circular arrow can allow you to alter the length of the arrow around the circle Here s a bunch of items you can copy paste and manipulate to make a clean systems diagram Fool around in PowerPoint to make your diagrams look good La Nina Ice Sheet Instability Water Temperatur e Figure 1 Warm Water Glacier Mass Lower Albedo Sea Floor Depth Paris Agreement Gov Regulation s Rise in Sea level Global Temperature Increased Regulations Figure 2 Refrigerants and Industrial Applications of HFCs HFC Levels in the Atmosphere Economic forces Climate Change Green House Affect Freeze Dates Favorable Fire Conditions Figure 3 Disturbance Invasive Species Prescrib edFire Rate Fire Grassland Coverage Woodland Reduction Woodland Coverage Constant Coverage Stock Prison Population in an industrialized country Mandatory Minimum Sentencing Convictions Prison Population Release Criminal Skill Transfer Criminal Activity Low Job Opportunity Upon Release Stock Energy in the Earth Atmosphere Climate System Land Use Change Fossil Fuel Burning Sunspots Greenhouse Gases Sunlight Waste Heat Energy in the Earth System Geothermal Reflected Light Cloud Formation I only track two inputs of energy into the Earth system although there are others The Earth gives off heat geothermal volcanoes etc but gets the vast majority of energy from the sun Sunspots may increase the energy from the Sun but as we saw with Ben Santer sunspots don t add a whole lot to the energy in the Earth system If thermal energy increases in the Earth system it could mean more evaporation which would mean more clouds which would mean more reflected sunlight HOWEVER keep in mind that water vapor and water droplets also absorb significant amounts of waste heat when the sun don t shine but also even when it does so they contribute as well to potential decreases Greenhouse gases also slow the rate of escape for waste heat as well which are the result of fossil fuel burning In a deeper systems thinking way land use changes can also mean less CO2 retention and also increases in reflected light you could track this with CO2 as a stock with its own box but Stock Trees in a forest that has some logging Government Subsidies Capital Investment Artificial Planting Logging Tree Recruits Total Tree Mass Tree Death Parasites Climate Change Artificial planting by loggers may mean that there are more recruits than the natural rate Subsidies by government may encourage more logging meaning total tree mass stock may go down without sustainability policies Climate change has also shown to have an impact on parasites e g pine beetles which can accelerate tree death Stock Population of a burgeoning tech city Younger Immigrants Births Deaths City Population Immigration Emigration Housing Availability Housing Prices Here we can see that younger immigrants into the city may mean that the death rate in terms of deaths per 100 000 people yr may go down but could eventually go back up as the population ages You can also see the potential effects on housing availability leading to prices going up When prices go up poorer people may leave the city limits Stock Installed rooftop photovoltaic PV systems Government Subsidies Installations Keeping up with the Joneses Rooftop PV Systems Removal Information About Neighbors Installations There are two potential factors listed here that suggest that PV installations could be affected When government subsidies remain installations may stay high If subsidies go away then installations could go down There s also an effect associated with neighbor perception which again could increase installations
