The Heat Score for Canada, powered by AISIX, uses a downscaled, bias corrected, multi-model ensemble for maximum daily temperature by mid-century for a middle-of-the-road climate change scenario (SSP2). The dataset simulates future temperatures at a 10km scale.

To make the temperature values easier to understand, Aisix classified them into 5 classes. The classification is based on statistical distribution of temperature values. Each class is defined by the rounded 10th percentile breaks above the mean temperature (27 °C) below the 60th parallel.

The data adequately captures future trends in regional temperatures, but further extremes should be expected at finer scales. This is because the operating resolution of climate model products combines and averages intricate terrain and atmospheric features such as mountainous terrain and urban heat islands into larger grid cells. The SSP2 climate change scenario assumes that socio-economic trends do not shift significantly from current global patterns. This climate change scenario represents a middle ground between a low-warming future characterized by proactive societal mitigation of a changing climate, and a high-warming future that does not mitigate climate change in pursuit of socio-economic development.

Aisix derives heat scores from global circulation models.

Heat Fact: when assessing heat risk to human health, a combination of humidity and heat called humidex is used instead of just measured temperature.

 

AISIX Score

To enhance the accuracy and transparency of the probabilities, we have implemented a classification system consisting of five distinct levels: 1 to 5, corresponding to daily maximum temperatures:

Please Note:
AISIX scores are driven by probabilities, which means they are not certain. It’s important to be careful when understanding these scores. Remember that even if something is likely, it is not guaranteed. The opposite is also true. To understand more, please read AISIX disclaimers.

 

FAQs

  1. What is a heat risk score?
    Aisix’s heat risk score represents how high temperatures will be by 2050 for a given location compared the average for Canada. The higher the score, the higher the maximum temperatures by mid-century, the higher the heat risk.
  2. How often is the heat risk score updated?
    Heat risk scores are typically updated annually to reflect new data and environmental changes. 
  3. Is my property’s heat risk score based on current weather conditions?
    While the base score incorporates historical and geographical data, it may not reflect real time conditions.
  4. Can the heat risk score change over time?
    Yes, the score can change due to factors like climatic changes and improvements in risk assessment technologies. Regular updates incorporate these changes to keep the score as accurate as possible.
  5. Who can I contact for more detailed information about my property’s heat risk?
    For more detailed information, contact info@aisix.ca
  6. What should I do if I disagree with my heat risk score?
    If you disagree with your score, you can request a review or reassessment.
