Canada’s Changing Climate Report

Canada's Changing Climate ReportEnvironment and Climate Change Canada recently released CCCR2019 Canada’s Changing Climate Report.  The report itself is 444 pages, and reports on the known science of climate change, and the most accurate predictions of that science.  Key points from the report are:

  • Annual mean temperature in Ontario has already increased 1.3C, largest in the winter at 2.0C.  Expectations are that the annual mean temperature will rise a further 1.5C to 2.3C.
  • Annual precipitation in Ontario has increased 9.7%, and is expected to increase a further 5.3% to 17.3%.
  • Overall, Canada will warm at twice the rate as the global average.
  • Extreme hot weather will become more frequent and more intense, increasing drought (despite increased precipitation) and wildfire risks.
    • If temperatures rise an additional 1C (we meet Paris targets), 50 year extremes will come every 10 years, 20 year extremes every 5 years and 10 year extremes every 3 years.
    • Indicators of climate change
      Multiple independent indicators of a changing global climate

      If temperature rises an additional 3.7C, 50 year extremes will come every 1.5 years.

  • More intense rainfalls will contribute to increased urban flood risks.
    • If temperatures rise an additional 1C (we meet Paris targets), 50 year rain storms will come every 30 years, 20 year storms every 11 years and 10 year storms every 6 years.
    • If temperature rises an additional 3.7C, 50 year rain storms will come every 10 years, 20 year storms every 5 years and 10 year storms every 3 years.

This changing climate report is the latest of many showing the urgency in reducing greenhouse gas emissions.  Efficiency Engineering is proud to be helping our clients to do their part.  Not only does reducing GHGs make environmental sense, but our clients are finding it makes financial sense as well.
