Thank you, Madam Chair.
To our witnesses here in person, it's great to know you're from Calgary. I went to school in Calgary. I took my master's there—my graduate degree—and taught at the University of Calgary. I'm going to try to get to you in the latter part of my time.
However, I want to go to Dr. Levasseur.
I noticed, here in my notes, that you're the Canada research chair in measuring the impact of human activity on climate change, so I think your testimony to this committee is extremely relevant. Unfortunately, there are still people in society who do not believe that human activity leads to climate change.
Knowing we only have five minutes or so, could you please provide a summary of your most recent findings with regard to how human activity drives climate change?
