The Intergovernmental Panel on Climate Change (IPCC) issued its Fourth Assessment Report (AR4) in 2007.

The Technical Summary of the report by Working Group II summarizes the projected physical impacts of climate change.

This study described anticipated impacts of varying levels of temperature change (e.g. 1 degree Celsius, 2 degrees Celsius, etc.)

The document included as an attachment to this page, IPCCchart.pdf, summarizes the data included in the model used in the CoLab.
