Introduction to climate scenarios

Climate scenarios from the Coupled Model Intercomparison Project Phase 5 (CMIP5; Taylor et al., 2012) climate models, whose results were used in the latest Intergovernmental Panel on Climate Change (IPCC) Assessment Report (AR5), are available.

Data are available for download at various temporal resolutions:

  • Time series: climate variables at daily, monthly, seasonal or annual scale
  • Reference period: projections are expressed as anomalies with respect to the reference period of 1986-2005 for graphics and tables

Climate scenarios based on model output used in the IPCC Third Assessment Report (TAR) and the Fourth Assessment Report (AR4) are also available on CCDS.

Users requiring further information on the Environment and Climate Change Canada climate modelling program are invited to visit the Canadian Centre for Climate Modeling and Analysis (CCCma) information page.
