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). Key projected climate trends are summarized below:
- Under the RCP8.5 emissions pathway, average temperatures are projected to increase by 2.9°C by 2080-2099, approximately 1°C less than the global average.
- Under the RCP2.6 emissions pathway, average temperatures are projected to increase by 7°C by 2080-2009, 0.2°C less than the global average.
- Under all emissions scenarios, projected maximum and minimum temperature increases are greater than increases in the average temperature.
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.
