This simple radiation balance model shows the greenhouse effect that an atmosphere can have in warming a planet.  By trapping some of the radiation emitted by the planet the atmosphere can cause the surface to become warmer than it otherwise would be.

Environment Population Growth Demographics

The World3 model is a detailed simulation of human population growth from 1900 into the future. It includes many environmental and demographic factors.

Use the sliders to experiment with the initial amount of non-renewable resources to see how these affect the simulation. Does increasing the amount of non-renewable resources (which could occur through the development of better exploration technologies - or could mean that the estimations were wrong) improve our future? Please note that you only see 5 digits of a much bigger number of the resources in the display, which might look awkward when moving the slider. 

Also, experiment with the start date of a more environmentally focused policy (in the basic scenario it is set to a year in the far future, i.e. it effectively is deactivated).

The World Socio-Economics model is computer model to simulate the consequence of interactions between the earth and human systems based on the World3 model by the work of Club of Rome, The Limits to Growth[1].

The World3 model builds by system dynamics theory that is has an approach to understanding the nonlinear behaviour of complex systems over time using stocks, flows, feedback loops, table functions and time delays.

The Limits to Growth concludes that, without substantial changes in resource consumption, "the most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity". 

Since the World3 model was originally created, it has had minor tweaks to get to the World3-91 model used in the book Beyond the Limits[2], later improved to get the World3-03 model used in the book Limits to Growth: the 30 year update[3].
