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 across Cambodia by 0.7-2.7°C by the 2060's, and 1.4-4.3°C by the 2090's.
- All projections indicate substantial increases in the frequency of days and nights that are considered ‘hot’ in current climate, with hot days increasing by 14-49% and hot nights increasing by 24-68% by 2060.
- All projections indicate decreases in the frequency of days and nights that are considered ‘cold,’ with these events becoming exceedingly rare.
- As yet it is not possible to get a clear picture for precipitation change, due to large model uncertainties. However, increases in rainfall appear to be likely during the monsoon season for Cambodia.
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.
