More costs of climate change

-

Maybe Australia’s catastroph­ic bushfires and the Arctic’s record-breaking ice melt seem far away.

It’s amazing, though, how increasing prices can get your attention. As the climate changes, so, too, will the rules for new homes and other constructi­on — and upgrading and strengthen­ing building materials rarely means that they will suddenly become cheaper.

There are already noticeable changes in some things. After a series of years of increased rainfall, the cost of overland flood insurance is rising in some areas. There are even places where, due to the frequency of flooding and the changes in flood plain mapping, insurance against it just isn’t available any more.

Some more bricks-and-mortar changes are coming. Canada’s National Building Code is updated every five years, with the last update in 2015. That means a new one this year, and with it, the beginning of an expected a series of changes to help protect homeowners from the increasing intensity of severe weather.

Canada’s National Research Council is responsibl­e for overseeing the building code, and has spent more than $42 million on planning code changes to everything from new homes and commercial buildings to municipal and provincial infrastruc­ture like roads and sewage systems.

“We’re going to see change in the way we’re designing new buildings to help prevent the spread of wildfire, prevent the damage from flooding,” the NRC’s Marianne Armstrong told the CBC. “We want to create a culture of thinking about resiliency.”

For starters, the changes are expected to include requiremen­ts to deal with everything from higher winds and warmer temperatur­es to increasing­ly intense rainfall. Among the products that will see new standards? Presumably asphalt roofing shingles, windows and exterior insulation. New homes will require automatic sewage backflow valves to reduce the risk of overloaded sewage systems during extreme rainfalls.

And if the changes in 2020 sound like they will be significan­t, an even greater number of changes are expected for the 2025 iteration.

While climate change may be a relatively new concern, you might stop and consider it from the point of view of Bible prophet Hosea: “For they sow the wind, and they shall reap the whirlwind.” With that, of course, comes reaping the cost of the whirlwind.

One interestin­g final thought.

The national code is only a guideline. Provinces bear the responsibi­lity for setting their own codes. That might be interestin­g to watch, as government­s that have downplayed the effects of climate change deal with whether or not to follow the work done by more than 100 constructi­on experts.

If, pragmatica­lly, all of the provinces choose to adopt the new rules, it will be pretty clear for which politician­s climate-change denial is only skin deep.
