How do I use it?

Climate change is influenced by many interacting processes. This web model lets you experiment with these, simply by moving controls with your mouse and observing the effect instantly on plots ranging from emissions to impacts.
The curves are calculated by an efficient Java implementation of simple carbon and climate models based on those used in the recent Intergovernmental Panel on Climate Change Third Assessment Report
(see science models).
