Examining the IPCC Fourth assessment report (AR 4 )
The Intergovernmental Panel on Climate Change (IPCC) has a rich repository of figures and data, and because these data are likely to influence some policy actions in your future, it's worthwhile to examine the IPCC reports. The data and conclusions, as well as the points of uncertainty, are presented there to help the public understand the issues with the best available data.
An excellent overview is in the Summary for Policy Makers (SPM) that accompanies the Fourth Assessment Report. Find a copy of this report on Connect. Examine the figures in the report and answer questions in Connect to demonstrate your understanding of the ideas and the issues.
