Explore historical and projected climate data, climate data by sector, impacts, key vulnerabilities and what adaptation measures are being taken. Explore the overview for a general context of how climate change is affecting Comoros.

Climate Data Projections

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 temperature in the Comoros is projected to increase between 0.8-2.1°C by the 2060's and 1.2-3.6°C by the 2090's.
  • Projections indicate all seasons will experience similar rates of increase in temperature.


  • Projections for mean annual precipitation show a large range of changes that covers both negative and positive changes.
  • Seasonal projections tend toward decreases in rainfall during dry season of June to November, while projections tend toward increases in rainy season rainfall, specifically the months of December to February. 

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.
