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.
- Climate change modelling have projected an increase in average annual temperature from 0.7 to 2.5 °C by 2060 and 1.2 to 3.7°C by 2090.
- The models also suggest that rainfall could further decrease by up to 20% by 2100.
- In addition, climate variability is predicted to increase, with more storms, ﬂoods, and droughts and a shorter rainy season.
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.
