Summary View help for Summary

The science of global warming has reached a consensus on the high likelihood of substantial warming over the coming century. Nations have taken but limited steps to reduce greenhouse gas emissions since the first agreement at Kyoto in 1997, and little progress was made at the Copenhagen meeting in December 2009. The present study examines alternative outcomes for emissions, climate change, and damages under different policy scenarios. It uses an updated version of the RICE model (Regional Integrated model of Climate and the Economy). New projections suggest that substantial future warming will occur if no abatement policies are implemented. The model also calculates the path of carbon prices necessary to keep the increase in global mean temperature to 2 degrees C or less in an efficient manner. The carbon price for 2010 associated with that goal is estimated to be $59 per ton (at 2005 prices), compared with an effective global average price today of around $5 per ton. However, it is unlikely that the Copenhagen temperature goal will be attained even if countries meet their ambitious stated objectives under the Copenhagen Accord. This file is the program used to create the runs. The file is RICE_042510.xlsm
