Climate Data Projections

The climate science community sources a suite of models to inform decision makers on future climate. Among the most widely used are GCMs (Global Climate Models or Earth System Models) that capture the non-linear complexity of the Earth to represent changes across the climate system for key processes and contexts. Future climate projections are presented in three main forms, multi-model ensemble, range of climate models, and deviation from historical baseline. Climate Change Knowledge Portal (CCKP) allows users to explore further climate indices derived from GCMs used in IPCC Fifth Assessment Report (AR5) report by different timeframes, statistics, emission scenarios, and models in map and charts.  Data can be presented per individual models or through the multi-model ensemble. CCKP prioritizes analysis using multi-model ensembles as they are more robust and have proven to be most successful in representing expected changes. A detailed metadata can be found here.

According to the IPCC AR5 and Turn Down the Heat report:

  • Substantial increases in this measure of meteorological drought are projected in Australia.
  • In southwestern Australia, the tendency manifested in the majority of model simulations is for longer dry periods and is consistent with the average decreases.
  • Large increases in seasonal sea level pressure are found in regions of sub-tropical drying such as the Australia in JJA.
  • climate change is projected to diminish per-capita water availability in Australia.
