Expert warns Ont. climate changes means more frequent extreme weather

"If you're in the business of emergency management, don't just assume the frequency (of storms) in the past will apply in the future," said Barry Smit of the University of Guelph. Smit told an all-party committee studying Ontario's emergency preparedness that extreme weather, like last month's heavy rain and flooding in Peterborough, is "more likely to occur with climate change than it would otherwise. People planning for Peterborough shouldn't say, 'Well, we can relax.' "

Smit said scientists are still studying the frequency and severity of the extreme weather events, but added they expect central Canada to be hit with more severe storms than in the past as the effects of climate change increase.

He said the possible impacts of a warmer climate, which could include more frequent heavy rains and more drought, should be incorporated into Ontario's agricultural, municipal and emergency management policies.

"We can plan for climate change if we choose, and emergency planning is a great place to do it."

Smit also said politicians should try to stop climate change, but admitted that's difficult to accomplish, and suggested the best way to proceed is for governments to "adapt" to the changing environment.

"Include the risks associated with climate change in your resource management policies, strategies and decision making, for individuals, for businesses, (and) for all levels of governments," he said.

Smit also warned politicians to do their utmost to bring the public onside with climate change if they hope to truly adapt.

"Unless the general public believes it's an issue in some way, then not much is going to be done," said Smit, who warned that even trying to explain the science of climate change to people is a daunting task.

"When I've seen that done, even by exciting presenters and educators, most of the audience falls asleep or leaves the room, even when I've done it."

The legislature's standing committee on justice policy is holding public hearings this month on a review of Ontario's emergency management systems.
