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:
- Mean annual temperature is projected to increase by 1.5°C by 2050, and the rate of warming is projected to increase with more frequent heat waves and more frost days.
- Rainfall is expected to increase, in relation to the 1961-1990 reference period, by 2%, 4% and 6% by 2020, 2050 and 2080, respectively.
- Analysis indicates seasonal differences in precipitation trends, with a mild drying effect for Timor-Leste over the June-August period by 2080.
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.
