Canada’s climate is warming twice as fast as global average

The science is clear. Human activity is driving unprecedented changes in Earth’s climate, posing significant risks to the health and well-being of Canadians, communities and the economy.


Just released, Canada’s Changing Climate Report provides the first in-depth, stand-alone assessment of how and why Canada’s climate has changed, and what changes are projected for the future.

This is the first report completed as part of the National Assessment Canada in a Changing Climate: Advancing our Knowledge for Action, led by Natural Resources Canada. It provides the climate science foundation for the forthcoming reports by addressing the impacts of climate change on our communities, environment, and economy, as well as how we are adapting to reduce risk.

The assessment confirms that Canada’s climate has warmed in response to global emissions of carbon dioxide from human activity. The effects of widespread warming are already evident in many parts of Canada and are projected to intensify in the near future. A warmer climate will affect the frequency and intensity of forest fires, the extent and duration of snow and ice cover, precipitation, permafrost temperatures, and other extremes of weather and climate, as well as freshwater availability, rising of sea level, and other properties of the oceans surrounding Canada.


The following headline statements tell a concise story about Canada’s changing climate based on the findings of this report:

  • Canada’s climate has warmed and will warm further in the future, driven by human influence.
  • Both past and future warming in Canada is, on average, about double the magnitude of global warming.
  • Oceans surrounding Canada have warmed, become more acidic, and less oxygenated, consistent with observed global ocean changes over the past century.
  • The effects of widespread warming are evident in many parts of Canada and are projected to intensify in the future.
  • Precipitation is projected to increase for most of Canada, on average, although summer rainfall may decrease in some areas.
  • The seasonal availability of freshwater is changing with an increased risk of water supply shortages in summer.
  • A warmer climate will intensify some weather extremes in the future.
  • Canadian areas of the Arctic and Atlantic oceans have experienced longer and more widespread sea-ice-free conditions.
  • Coastal flooding is expected to increase in many areas of Canada because of local sea level rise.
  • The rate and magnitude of climate change under high versus low emission scenarios project two very different futures for Canada.
