Canada’s Changing Climate Report

Canada’s Changing Climate Report (CCCR), completed in 2019, assessed the state of knowledge on how and why Canada’s climate has changed and what changes are projected for the future. The report is national in scope and provides the Canadian context to the issue of global-scale climate change. The CCCR builds on information from Intergovernmental Panel on Climate Change (IPCC) assessments available at the time.
