Climate change, which many consider to be the issue of the 21st century, has become a central topic in Canadian public discourse and politics. Extreme weather and climate events – including drought, flooding, extreme heat, intense storms and wildfire – are perceived as becoming more frequent and intense due to climate change, and consequently causing more damage. It is important that we all learn more about these impacts, and how to address them. Scientists need to observe, understand and predict the changes, engineers need to take full account of their impact on the environment and all of us need to be aware of what is taking place.
