Description
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).
