A recent study predicts a future with higher temperatures and increased precipitation in northeastern B.C., along with more extreme weather events affecting communities that have faced major natural disasters in the past decade.
By the 2050s, average temperatures in the region could climb by up to three degrees, escalating to five degrees by the 2080s. This shift may make summers resemble those in the Okanagan, while January temperatures could mimic historical March levels.
The Fraser Basin Council researchers emphasize that these changes will have wide-ranging effects on infrastructure, water resources, and disaster preparedness, impacting how communities tackle challenges such as floods, wildfires, and evacuations.
Jim Vanderwal, a researcher involved in the study, stresses that the focus is on community-level planning for the future rather than engaging in climate change debates. The report, funded by the federal government, was undertaken on behalf of local governments and Indigenous communities in the region, known for its extreme weather patterns in recent years.
The aftermath of severe floods in 2016, which severed the region’s main road connection to the Lower Mainland, and the escalation of wildfires since 2022, including the largest recorded in B.C. history, such as the Donnie Creek fire, have displaced thousands of residents in various communities, underscoring the long-lasting impacts of such disruptions.
Fort St. John has emerged as a safe haven for wildfire evacuees, placing significant demands on city staff and volunteers. Milo MacDonald, the city’s chief administrative officer, highlights the city’s commitment to aiding neighbors during crises and acknowledges the growing pressures necessitating continuous preparedness.
The changing climate is already manifesting in various aspects of city operations in Fort St. John, notably through an increased frequency of freeze-thaw cycles in winter, leading to deteriorating infrastructure like sidewalks and buildings. The report forecasts a doubling of freeze-thaw days by 2080, indicating a pressing need for proactive measures to mitigate these impacts.
In terms of water resources, the study anticipates longer growing seasons but also more intense heatwaves, shorter winters with increased rainfall, and reduced snowfall in spring and fall, resulting in more frequent droughts and lower streamflows. Recent water shortages in Dawson Creek underscore the importance of planning for future water supply needs in the face of changing climate conditions and infrastructure challenges.
The report urges communities to prepare for more water scarcity incidents and invest in resilient infrastructure to adapt to the evolving climate patterns. Planning for sustainable water management and infrastructure upgrades will be essential to mitigate the impacts of climate change on communities in northeastern B.C.
