After this summer’s extreme heat, drought, smoke and wildfires, it is obvious that all predictions are off and all we can expect is the unexpected. Most graphs that illustrate climate change show exponential lines that move increasingly upward, so thus the impacts will also be increasing in number and scope. We can also no longer be smug by thinking the damages and deaths will be somewhere else, as it is now clear that we are every bit as vulnerable in British Columbia and here in the Shuswap.

In the past, climate scientists predicted rising temperatures, more severe storms, water shortages, and extreme precipitation events. There was nary a word about what could happen due to the arctic warming at a faster rate than the rest of the planet, until the heat dome settled over the Pacific Northwest. We now learn that higher temperatures in the far north make the jet stream unstable and instead of moving in a sold band around the earth, it is now fragmented and wobbles causing weather systems to stall.

Extreme weather now stalls for days, creating intense heat in some areas, and record rainfall deluges elsewhere. Just outside the boundary of this late June’s heat dome, there were areas of the central U.S. that received upwards of a foot of rain. That means the Shuswap could one day face similar massive rain showers, like the one over the eastern Rockies that flooded Calgary a few years ago.

Perhaps the worst part of the impacts occurring is that many of them result in feedback mechanisms that add yet more carbon to the atmosphere. Burnt forests produce more carbon and methane for years after the fires from the decaying fibre and the lack of trees means less carbon is absorbed. The smoke settles on glaciers darkening the ice and snow causing more heat absorption that accelerates the melting.

For three out of the last five years, B.C. has experienced devastating wildfires covering over three million hectares, with intense smoke filling the valleys. If summers like these become the norm, it could pose serious consequences for the Shuswap economy based on tourism. As well, there will be long term health impacts from the polluted air filling our lungs year after year, especially for those who did not mask up when the air quality was terrible.

The drought resulted in enormous losses for farmers in the prairies, which will result in grain shortages. Entire herds of cattle had to be sold due to the lack of feed and water. In California, where many reservoirs are nearly empty, farmers had to give up. The result will be a rise in food prices and likely food shortages this coming winter and beyond.

Both of these fires burned much of Anstey – Hunakwa Provincial Park

No longer are we just reading about death and destruction in faraway third world countries or the hurricane, tornado and wildfire plagued U.S., now that 569 people perished from the heat in this province. The entire town of Lytton was reduced to ashes after it experienced record-breaking temperature and another community here in the Shuswap, Monte Lake, was also seriously scorched. Fires also nearly destroyed two of the Shuswap’s premier parks, Momich Lake, which had already burned in 2009, and Anstey-Hunakwa.

The Momich Lake fires also burned part of the land adjacent to Humamilt Lake

Fortunately, homes were spared in Sicamous and along Mara Lake from the Two-Mile fire, but parts of the steep hillsides were seriously burned, especially former clearcuts. This hillside has seen multiple landslides after heavy rain events and with many trees now reduced to ashes, there could be more slides in upcoming years.

As efforts to mitigate climate change by reducing emissions continue to fizzle, the planet is posed to continue to get warmer for many decades to come. The focus must now be on survival and the only way to achieve it is through improved adaptation measures. The provincial government is aware of this need, but its efforts to date have been insufficient and few of the recommendations from wildfire reports have been followed. Clearly, there is a need for local governments to take up the slack and make concerted efforts to help ensure the Shuswap is better able to weather the future.

POSTSCRIPT

Summer in the Shuswap is what so many residents yearn for to enjoy the lake, hiking, and biking. When the skies are full of smoke and it is unsafe to go outside, many of us become stressed, especially when you add concerns about a fire burning down your home. Could this summer become the norm? If so, our lives will be greatly impacted and the much of the joy of living here will be gone. Our future looks so uncertain now, but we must persevere and find ways to cope with the stress.

British Columbia’s forests have become the largest source of carbon dioxide, more than transportation, fracking, heating and all other sources combined. One day logging will have to be scaled back significantly and tree-planting will have to be increased significantly, using tree species that can survive in higher temperatures. A better source of fibre for building and paper could come from hemp, which should be grown on all under-utilized farmland. Hemp can absorb more carbon every year than trees and it produces more fibre per hectare. It is also a great source of edible protein and oil from the seeds.

Fortunately, humans are good at adapting. As the planet heats up and its life support system breaks down, we will indeed find a way to survive, even if it means living underground. But in the meantime, we need to minimize our risks from heat, storms, wildfires and smoke. As well, we need to continue enjoying life to its fullest including recreating outside during low-health risk conditions.

Everything Shuswap

by Jim Cooperman

Everything Shuswap explores the region’s rich eco-types and its interwoven historical record. It’s a textbook for understanding one of the most beautiful and least understood landscapes and it should be mandatory reading for anyone who lives in or visits the Shuswap.”
