Extreme Weather Event Attribution for Canada with Climate Model Comparisons

A dataset from Environment and Climate Change Canada, last updated in May 2026, detailing the influence of human-caused climate change on extreme weather events. It uses a rapid attribution system to compare event likelihoods across pre-industrial, current, and projected future climates for 17 regions covering Canada. The data includes analyses of extreme heat waves, cold, and precipitation events, categorized by a seven-point likelihood scale.

Use Cases

• Quantifying the change in likelihood of specific heat waves based on the seven-point attribution scale.
• Comparing extreme weather event frequencies between historical and projected future climates for Canadian regions.
• Analyzing regional patterns of climate change influence on extreme precipitation and cold events.

Strengths

• Data is produced by a national environmental agency, Environment and Climate Change Canada.
• Analysis covers 17 distinct regions spanning all of Canada.
• Employs a defined seven-statement scale for quantifying climate change influence.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified as the last update timestamp is from the future (2026-05-21).
