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 temperatures are projected to increase between 1.0-2.9°C by 2060's and 1.5-4.7°C by the 2090's.
• The rate of warming is projected to be largest in the interior and slower in the western coastal areas of the country.

Precipitation

• Model projections for average annual precipitation display a wide range of changes over Cameroon.
• By the 2090's projected changes in rainfall range between -12 to +20 mm per month, with ensemble means around +1 to -3 mm per month.

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.
