THIS MODEL BY GUY LAKEMAN, FROM METRICS OBTAINED USING A MORE COMPREHENSIVE VENSIM SOFTWARE MODEL, SHOWS CURRENT CONDITIONS CREATED BY THE LATEST WEATHER EXTREMES AND LOSS OF ARABLE LAND BY THE  ALBEDO EFECT MELTING THE POLAR CAPS TOGETHER WITH NORTHERN JETSTREAM SHIFT NORTHWARDS, AND A NECESSITY TO ACT BEFORE THERE IS HUGE SUFFERING.
BY SETTING THE NEW ECOLOGICAL POLICIES TO 2015 WE CAN SEE THAT SOME POPULATIONS CAN BE SAVED BUT CITIES WILL SUFFER MOST.

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 low birth-rate, 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.

A very simple thermodynamic model of a planet, which includes first order approximations of its radiation balance (black bodies), including two radiation modulating effects i.e. albedo and green house and two heat storages (ocean and atmosphere). It is a lumped model which does not consider spatial variations and resulting mass transports - thus no heat exchange between e.g. equatorial and polar regions...
As a consequence all values are surface specific i.e. per square meter. E.g. the energy balance is the  balance in  W/m² and the heat reservoirs are water and air columns with a cross section of 1 m²...
