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) improve our future? Also, experiment with the start date of a more environmentally focused policy.

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.

Modelling after Earth, this is a model of the  greenhouse effect  has in increasing the temperature. By trapping some of the radiation emitted by the planet the atmosphere can is itself a positive feedback loop.

This model demonstrates positive feedback that decreases the surface albedo and increases the greenhouse effect and examines its impact on this planet's temperature.
