A System Dynamics Approach to Global Warming (Noah) Junho Kang

Purpose/Goals Create a convincing model of global warming scenario Complicated enough to explain the whole scenario to a reasonable extent, but simple enough to be understood and applied elsewhere

Scope of the Project Although more narrowing down of the topic is required later, current scope of the project is to estimate, to a certain degree, the effects that increasing amount of Carbon Dioxide gas will have on the Earth's atmosphere. The "effects" currently include, but is not limited to, global temperatures, frequency of hurricanes, methane release, and other consequences that will arise from these effects.

Expected Results Direct Cause-and-effect relationship between Earth’s Global Temperature and Carbon Dioxide Concentration Demonstrate the impact of Global Warming

Background Daisyworld Parallel Computing-based Climate Simulations System Dynamics Modeling and Agent- based Modeling

Current Progress on Code Output system consisting of an Output file and a graph Automatic external addition correction ever 10,000 ticks during run

Current Results Current (somewhat dubious) results show a relationship between global temperature and Carbon Dioxide concentration in Atmosphere
