You can run a Climate Simulation!

 You can run a climate simulation yourself!

Click HERE, enter the data, and hit the Run Simulation button.

This simulation is called C-Learn. C-Learn is the 3-region, simplified version of the policy-maker-oriented C-ROADS (Climate Rapid Overview and Decision Support Simulator) simulator, which has been used in United Nations proceedings, the U.S. Congress, by top European Environment Officials, and undergone an external scientific review.

EXAMPLE

Here is what the simulation looks like for one particular scenario. It is very aggressive, calling for an 80% reduction in emissions by developed countries and 50% reduction by developing countries by 2050, with respect to 2005 levels, with reductions starting in 2012. Maximal afforestation sequestration and minimal deforestation is assumed. The temperature change by 2100 is 2.4 degrees C. 

Less aggressive scenarios will lead to higher rises in temperature.

 The following graphic was pasted from the C-LEARN site. Not all quantities show up in the graphic.
