- Climate models are complex, and there is a great deal of variability. This slide shows the results of nine global climate models run using an emissions scenario labelled A2, which assumes medium to high emissions.
- The predicted warmings vary from 1.5 to 6 degrees Celsius by the end of the century.However there is pretty close agreement between the models up to 2050 (within the lifetime of the majority of current undergraduates)indicating that global warming of the order of 1 or 2 degrees will occur.
