 The model starts in 1900. In the year 2000 you get the chance to set a new emission target and nominal time to reach it. Your aim is to have atmospheric CO2 stabilize at about 400 ppmv in 2100.  From Sterman, John D. (2008)   Risk Communication on Climate:  Mental Models and Mass Balance .  Science

 This common archetype of systems that include relapse or recidivism allows exploration of the unintended effects of increasing upstream capacity and swamping downstream capacity. The increase in the relapse rate eventually returns to swamp upstream capacity as well. A social welfare example, based

This common archetype of systems that include relapse or recidivism allows exploration of the unintended effects of increasing upstream capacity and swamping downstream capacity. The increase in the relapse rate eventually returns to swamp upstream capacity as well.

The purpose of this model is to have the user change the value of stocks, flows and converters to experience a variety of different graphical results. Understanding this generic model is important pre-requisite to learning about intravenous drugs in the body, radioactivity, self-esteem, water flowin
The purpose of this model is to have the user change the value of stocks, flows and converters to experience a variety of different graphical results. Understanding this generic model is important pre-requisite to learning about intravenous drugs in the body, radioactivity, self-esteem, water flowing from a drain and many other basic natural systems.
