CMIP6 climate scenarios
Coupled Model Intercomparison Project Phase 5 (CMIP5) scenarios are also available
Climate scenarios from the Coupled Model Intercomparison Project Phase 6 (CMIP6) global climate models (GCMs), whose results were used in the latest Intergovernmental Panel on Climate Change (IPCC) Assessment Report (AR6), are available. CMIP6 projections are based on the Shared Socio-economic Pathway (SSP) scenarios. For more information on CMIP6 and SSPs, please see the overview. The IPCC's interactive atlas offers regional information on projected changes in climate using CMIP6 data for the globe.
For a Canadian perspective, the time series graphs, maps, and tabular data presented here are based on a multi-model ensemble of CMIP6 GCMs interpolated to a common 1x1 degree grid. Global gridded formats are available for the multi-model ensembles as well as for individual GCM outputs. Please see the technical notes for more details.
A subset of CMIP6 daily predictor variables that can be used for statistical downscaling of GCMs are also available for download. For more information on the CMIP6 predictors, please see the technical documentation.
For these global time series datasets, the areal mean is computed on the common 1x1 degree grid using land points. Global multi-model ensemble mean datasets and Canadian plots are available for temperature and precipitation.
Due to model uncertainty and natural variability, the time series of each model and scenario over the common period 1900‑2100 are shown as anomalies relative to a baseline time period of 1995‑2014. The multi-model ensemble means (bolded) are also shown. While plots compare both the multi-model ensemble means and the results from individual contributing GCMs for Canada, only the multi-model ensemble mean is downloadable as a dataset (for the globe).
Finally, for the period 2081‑2100, the 20-year means are computed, and the box-and-whisker plots show the 25th, 50th (median), and 75th percentiles sampled over the distribution of the 20-year means of the model time series to include both natural variability and model spread.
Note: Graphs display only national data and NetCDFs contain the global dataset.
National maps and global datasets of projected changes in temperature and precipitation averaged over 20 years for the near term (2021‑2040), mid term (2041‑2060 and 2061‑2080), and end of century (2081‑2100) are given, relative to a reference period of 1995‑2014. For each variable, the 5th, 25th, 50th, 75th, and 95th percentile of the CMIP6 ensemble distribution are provided for SSP1‑1.9, SSP1‑2.6, SSP2‑4.5, SSP3‑7.0, SSP4‑6.0, and SSP5‑8.5.
