The climate science community sources a suite of global climate models to help decision makers understand the projections of future climate change and related impacts, among the most widely used are the Coupled Model Intercomparison Project, Phase 5 (CMIP5) models included in the IPCC's Fifth Assessment Report (AR5). Climate projections can be presented via individual models or through multi-model ensembles. The Climate Change Knowledge Portal (CCKP) supports the analysis of climate impacts using multi-model ensembles, as they represent the range and distribution of the most plausible projected outcomes when representing expected changes.

Temperature

• Mean annual temperature is projected to increase between 1.0-3.4°C by 2060's and 1.6-5.4°C by 2090's.

Precipitation

• Projections for mean annual rainfall exhibit a wide range in changes, varying from -15 to +9 mm per month by the 2090s with mean ensemble projections close to zero.
• Projections for mean annual precipitation from CMIP5 models indicate increases in precipitation over Chad throughout the 21st century under RCP8.5.
• Model projections for wet season rainfall (July-September) in southern Chad indicate increases.

This section provides the options to visualize climate variables and indices derived from scientifically vetted CMIP5 projections for different timeframes, statistics, emission scenarios, and climate models.
