Climate Research

Environment Canada carries out a comprehensive program of scientific research on the climate system and climate change.

The climate research agenda is driven by public concern about climate and climate change. Our objective is to help provide the scientific basis necessary for wise policy and decision-making by governments and the public.  To this end, working with partners, we generate and disseminate new knowledge and data on the behavior of the climate system, and its past, present and future states.  The results provide a basis for many climate-related services and products for Canadians, and for climate policy development.

Our climate research activities are at the leading edge of scientific knowledge and are focused in four areas of particular relevance to Canada:
