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.

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).
