This report is about how and why Canada’s climate has changed and what changes are projected for the future. Led by Environment and Climate Change Canada, this document is the first of a series to be released as part of Canada in a Changing Climate: Advancing our Knowledge for Action. It documents changes across Canada in temperature, precipitation, snow, ice, permafrost and freshwater availability as well as in Canada’s three oceans.

This first document of the series provides the climate-science foundation for upcoming reports, which will address the impacts of climate change on our communities, environment and economy, and how we are adapting.
