Record Ottawa River Flooding From Climate Change // Published on May 8, 2017
In July, 2013 downtown Calgary had record flooding with insured losses exceeding $6 Billion. Three weeks later, extensive Toronto flooding from torrential rains cost more than $1 Billion.
Now it is Ottawa’s turn, along with Gatineau and Montreal and many other regions in Ontario and Quebec.
It is surprisingly simple to connect all these events, although you may not like the explanation.

‘We’re in a Climate Change Emergency’
Such extreme weather is much more likely now because of climate change, scientists say. As the greenhouse gas effect warms the planet, they say floods, droughts, mudslides and other extreme weather events are expected to occur more often, and with greater ferocity.
“Climate change is a global problem, but the reason we care about it is because it’s impacting us in the places where we live,” said Katharine Hayhoe, a Canadian who is the co-director of the Climate Science Center at Texas Tech University. “It’s taking these weather patterns that we’ve seen before and…putting them on steroids, so to speak.”
Paul Beckwith, who works on climatology in the Department of Geography at the University of Ottawa, also said flooding is being exacerbated by the “whiplash” of extremely wet or dry weather that is the result of climate change [Clausius-Clapeyron rate].
“We’re getting a lot more extreme weather events around the planet, whether that be torrential rains leading to flooding, or really hot and dry temperatures leading to drought,” he said.
“These extreme weather events are much more severe, much more intense, they last longer, they’re happening more frequently, and they’re happening in areas where they didn’t happen before.”

He said the root cause was that the Arctic was warming faster than any other global hotspot. As white sea ice and snow cover give way to darker permafrost or open ocean, the process accelerates.
“I’ve been saying we’re in a climate change emergency, and therefore we have to respond as if it’s in an emergency,” he said.
That means eliminating fossil fuel emissions, a major driver of climate change, as a very first step, Beckwith added.
