Canadian Climate Change Scenarios Network


The CCCSN was originally launched in February 2005 with support from Environment Canada, the Climate Change Adaptation Fund (CCAF) and the University of Regina. Since January 2012, it has been wholly supported by Environment Canada

The CCCSN supports climate change impact and adaptation research in Canada and other partner countries through the provision of GCM scenarios, RCM scenarios and downscaling tools. In addition, the CCCSN can provide high level technical support for downscaling and impacts and adaptation research, access to existing research, access to new research tools as they are developed at the AIRS nodes and training in the use of these tools. The CCCSN supports academic researchers as well as other stakeholders outside of academia who require scenario information for decision- making.

The CCCSN staff would like to acknowledge the contributions of the Canadian Climate Impacts Scenarios project (CCIS) to impact assessment research in Canada and the support CCIS provides to climate impact assessment in British Columbia.

A number of individuals and organizations have helped in the development of the CCCSN website. We thank them all for their efforts and contributions to the site. The CCCSN consists of separate nodes, representing different regions of Canada and with their own research specialty.

What is the CCCSN?

The CCCSN will maintain Canada's reputation for preserving a leading-edge scenarios facility that will become one of the premier sources for Canadians and international researchers seeking information on climate change scenarios and impacts and adaptation research. The content of the network includes:

  • Canadian climate change scenarios derived from GCM (Global Climate Model) simulations, (particularly the Canadian model, available at the Canadian Centre for Climate Modeling and Analysis (CCCma), those scenarios recommended by the Intergovernmental Panel on Climate Change (IPCC) and the Program for Climate Model Diagnosis and Intercomparison (PCMDI) project. In addition, this website will provide regional scale/high resolution output from the Canadian Regional Climate Model (CRCM), through collaboration with the Ouranos consortium, along with information on other relevant GCM downscaling methods;
  • Bioclimate profiles for Canada;
  • Scenarios and impact and adaptation research documents from within and outside of Canada;
  • Links to IPCC guidelines on scenario use and interpretation;
  • On-line instructions for using scenarios and downscaling tools: the Statistical Downscaling Model (SDSM), the Automated Downscaling Tool (ASD) and a weather generator (LARS-WG);
  • Links to other tools used in impacts and adaptation research; and
  • Scenario Reports and selected scientific publications related to climate scenarios and impacts and adaptation research.

The network also allows the user to:

  • Visualize GCM and CRCM experiments, either as maps or through the use of graphical displays of data;
  • Facilitate the analysis and comparison of available simulations from GCMs and the CRCM, when comparable simulations are available for the same experiments;
  • Develop all relevant derived atmospheric variables based extremes to consider plausible anticipated changes in duration, frequency and intensity of weather extremes; and
  • Extract and download all available parameter data for a particular location or region.
