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.
- Mean annual temperatures are projected to increase by 2.1°C by 2050 under RCP8.5.
- A reduction in precipitation is expected for May (end of rainy season) and October (beginning of rainy season).
- Mean annual rainfall is projected to increase over Burundi by mid and late 21st century.
- Projections indicate increases in mean annual precipitation over eastern tropical Africa.
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.
