Featured Event – Planning for the future: deriving future climate IDF curves for the City of Calgary

The Canadian Centre for Climate Services (CCCS) is pleased to offer this webinar as part of its new Climate Services Speaker Series, aiming to promote awareness of climate services and their application in climate change adaptation work across Canada.

This presentation will highlight work done for the City of Calgary and the Calgary Airport Authority to develop several types of future climate change data, including future climate change IDF curves, and how this data is being integrated into design guidelines and planning.

Additionally, the Canadian Centre for Climate Services will briefly speak to new climate change-scaled IDF data that will soon be available on

Featured Product – Custom Heat Wave Frequency Analysis Tool

Heatwaves are a growing concern across Canada and climate change is increasing both the frequency and intensity of these events. How are heat waves in your part of the country expected to change?

To date, this has been a difficult question to answer. Different regions of Canada have different heat warning thresholds. For example in Toronto, a heat warning is issued when the daytime maximum temperature reaches or exceeds 31 °C and the nighttime minimum temperature remains above 20 °C for at least two days in a row, while in Whitehorse the criteria is 28 °C for the daytime high and 13 °C for the nighttime low.

The Heatwave Frequency Analysis Tool allows the user to select grid cells for a specific location on the Map and enter any custom threshold they want for daily minimum and maximum temperatures as well as the number of consecutive days the criteria must be met in order to count as a heat wave.

Learning Zone Update

New! The Understanding Shared Socio-economic Pathways (SSPs) article has been added to the Learning Zone. This article examines how SSPs differ from RCP scenarios and includes guidance on how to consider and incorporate SSPs in to climate risk assessments.

Buildings Climate Zones Projections

Climate has a major impact on a building’s energy performance. To ensure that a building can safely and comfortably withstand a wide range of weather conditions, building designers and engineers comply with local energy efficiency codes and thermal resistance requirements. These regulations dictate, among many things, the minimum requirements for certain thermal properties of building envelope components.

Using Climate Data to Assess Risks in the Transportation Sector

Extreme weather is a persistent threat to the transportation sector. Bridges, highways, winter roads, rail lines, shipping routes, and airport infrastructure are vulnerable to flooding rains, rising seas, hot temperatures, and high winds, just to name a few.

What’s Coming Next?

Climate change-scaled IDF data

We are putting the final touches on new IDF data on that account for projected increases in precipitation due to climate change. The new data have been computed using the temperature-scaling method outlined in this Learning Zone article.

IDF stands for intensity, duration and frequency. As the name suggests, IDF curves are a graphical way of presenting information about how frequently a location experiences rainfall events of varying intensities and durations. Conventionally, these curves are developed using historical rate-of-rainfall data. However, IDF curves based solely on an analysis of historical data are not suitable for understanding future risks. Furthermore, because our climate is already changing, they may not even be well suited for the present day.

Updates from the Regional Partners

ClimateWest and the Prairie Adaptation Research Collaborative (PARC) have collaborated to release a primer to explain the types of uncertainty associated with climate modelling. This plain language document explores why a primer is needed, the causes of uncertainty, and how to manage uncertainty for climate adaptation planning.
