This year (2023) the number and intensity of wildfires in Canada reached unprecedented levels. The previous record, set in 2014, was almost tripled. Furthermore, this year's fires have emitted almost three times as much greenhouse gasses as have all other sources. In a year like this one, even if we had managed to completely eliminate all of our fossil emissions, two thirds of our total emissions would still remain. No number of electric vehicles, solar panels, windmills, nuclear plants, or carbon-capture technologies would bring us anywhere near our emission reduction targets. Can the wildfire genie be put back into its bottle?
Perhaps all is not yet lost. Perhaps this year was a one-off. Perhaps climate change has nothing or little to do with the number, intensity, and frequency of 2023's GHG emitting wildfires. On the other hand, perhaps hotter temperatures for longer periods of time are drying out our forests and turning carbon sinks into tinder boxes, often ignited by a lightning strike or careless humans. Perhaps this years emissions will join all the other GHG already up there (Its been accumulating for centuries), creating even hotter conditions for even longer periods of time with greater frequency than ever, in what is called a positive feedback loop. What does the science say? Below is a graph of Canada's wildfire emissions in recent years:
This is an absolutely staggering increase in emissions. Especially at a time when we are trying, so far unsuccessfully, to reduce our fossil fuel emissions, as if those were our only problem. And our fossil fuel emissions must absolutely be reduced, but let's stop pretending they are the only source of Canada's GHG emissions.
To be sure, it may seem unfair to Canadians to have to accept responsibility for emissions resulting from an increase in wildfires which result from global pollution--pollution they think that Canada is doing relatively little to contribute to, compared to, say China. But nature makes no distinction between fair and unfair emissions. She readily accepts and processes and absorbs them all. And in the process nature herself is altered. We are already witnessing this.
Whether or not 2024's wildfires will be as bad as 2023, I'm guessing probably not. I'm hoping for a period of grace. But I do believe that we will continue to break records: heat records, rainfall records, hurricane and tornado records, drought records and yes, sooner or later wildfire emission records.
