The Canadian Climate Change Scenarios Network

The Canadian Climate Change Scenarios Network (CCCSN) provides leading-edge scientific projections of future climate conditions to assist resource managers, policy advisors and other decision-makers in their efforts to adapt to Canada's changing climate. The network has been developed by Environment Canada in partnership with Canadian universities.

What You Can Find on the Network

The Canadian Climate Change Scenarios Network provides climate change scenario information for Canadians and international researchers, through a national website with links to regional nodes. The CCCSN websites assemble and make accessible the most recent climate change model outputs from two dozen models worldwide, including those from the Canadian Centre for Climate Modelling and Analysis.This information includes climate model simulation outputs, bioclimate profiles, downscaling tools, reports and publications along with a number of visualization tools: interactive maps, tables, graphs, and raw data downloads. The site also allows users to analyse and compare atmospheric variables, and download data from all models for a particular location.

Sample Scenario: Significantly Warmer Winters

By the middle of this century, winter temperatures are expected to rise dramatically in Canada.  This scenario was produced by an ensemble of climate models (mean winter temperature change, 2041-2070 as compared to 1961-1990, SRES A1B, using IPCC AR4 climate models).

Helping Decision-Makers Adapt 

Climate change will affect Canada's water resources, energy demands, infrastructure and a host of other social and economic sectors.  In many sectors, there will be significant impacts, and decision-makers need to plan now for future change.  However, some uncertainty remains about how Canada's climate will change, particularly on a local or regional scale. 

To assist resource managers, policy advisors and other decision-makers, Environment Canada researchers, working in partnership with Canadian universities, have developed a series of plausible scenarios of future climate.  Using these scenarios, decision-makers can develop a range of adaptive strategies, and determine the most effective approach for their sector. 

Climate impact scenarios piece together the raw results of climate models (both global & regional) and observations, such as temperature and precipitation estimates, to create an image of possible future climate conditions. The scenarios are tailored to the unique needs of impacts and adaptation researchers in fields such as agriculture, forestry, fisheries and heath.

To ensure ready access to the latest research in this rapidly developing field, Environment Canada has created the Canadian Climate Change Scenarios Network to link researchers and decision-makers with scientific experts from the federal government and Canadian universities.
