That is the model that Treasury chose to use for the modelling. It is a model that I am advised was also used by the Intergovernmental Panel on Climate Change, and it is highly regarded and well established for this type of analysis. The cumulative global emissions in the scenarios in the government’s report are consistent with estimates of global emissions projected for the relevant stabilisation levels also presented in the Stern review, and I know that the senator would be familiar with those.

In relation to the Hadley Centre and the University of Victoria, Canada, as I said, I am advised that it was the model for the assessment of greenhouse gas induced climate change that was utilised by Treasury. I am advised that it is a model that incorporates a suite of coupled-gas-cycle climate and ice-melt models integrated into a single software package. This software allows the user to determine changes in greenhouse gas concentrations, global mean surface air temperature and sea level resulting from anthropogenic emissions. The current version of MAGICC was developed primarily with funding from the United States Environmental Protection Agency.
