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). According to the USAID Climate Risk Profile, key future climate trends include:
- An increase in mean annual temperature of 1.5° to 2.2°C by 2050.
- A decrease in mean annual precipitation of 1.1 to 3.5 percent by 2050, with the largest reductions in July and August.
- An 11 to 18 percent increase in the number of consecutive dry days by mid-century.
- A 21 to 31 percent increase in total annual precipitation on extreme rainfall days by mid-century.
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.
