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 Niger.

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. According to the USAID Climate Risk Profile, key future climate trends include:


  • A 3°- 6°C rise in average temperatures is expected by 2100, with +4°C in Continental Sahel (Mali, Chad, Burkina Faso, Niger).
  • Maximum warming affects summer months (June–September) and minimum temperatures.
  • A decrease in frequency of days and nights that are considered ‘cold’ is projected; in much of the region ‘cold’ nights will not occur at all by the 2090s.


  • Uncertain precipitation projections due to high inter-annual variation, but inter-annual and spatial variability are expected to increase.
  • Reduced duration of rainy season, with increased extreme rainfall events in the south.

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.
