Summary[edit]

Description
English: This graph shows projected changes in global mean temperature between the years 2000 and 2100 for a range of climate change mitigation scenarios. Temperatures are measured in degrees celsius, and are relative to pre-industrial levels.

Projections for 5 scenarios are shown. Each scenario is designed to stabilize atmospheric GHG concentrations at a different level: 450, 520, 670, 970 and 1390 ppmv. A summary table of the graph data is given in a later section.

These are the "A2r" mitigation scenarios. The projections assume a climate sensitivity of 3.0 °C.
