Canada is warming twice as fast in comparison to the rest of the world, with changes already evident and spreading across the country, a new scientific report by the federal government released publicly on Tuesday finds.
Canada’s Changing Climate Report, publicized as a federal carbon tax comes into play for the provinces that don’t already employ one, warns that some of the effects are probably irreversible at this point.
“Northern Canada has warmed and will continue to warm at more than double the global rate,” the document reads, adding that there have been major changes to the Arctic and Atlantic Oceans.

Coastal flooding is expected to increase in many areas of Canada due to local sea level rise, impacting local industries and infrastructure.
The rate and magnitude of climate change under high versus low emission scenarios project two very different futures for Canada, the report says.
“Scenarios with large and rapid warming illustrate the profound effects on Canadian climate of continued growth in greenhouse gas emissions.”
However, scenarios with limited global warming will only occur if Canada and the rest of the world synchronize to reduce carbon emissions to near zero early in the second half of the century and reduce emissions of other greenhouse gases substantially.
This report was years in the making and it’s release follows findings from the United Nations warning that humans have 12 years to limit climate change before the risk for droughts, weather and extreme poverty will significantly increase for millions of people.
The climate change report found several key findings over the years of research:
- 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.
- Oceans surrounding Canada have warmed, become more acidic, and less oxygenated, consistent with observed global ocean changes over the past century.
