Is climate change really behind Canada's massive 2026 wildfires, or is it forest mismanagement like Trump says?

Trump has blamed Canada's wildfires (and the smoke drifting into the US) on poor forest management, but a new study is trending saying it's climate change. What does the actual research say?

A rapid-attribution study released August 6, 2026 by World Weather Attribution — an international group of climate scientists who specialize in calculating how much climate change influences specific extreme weather events — found that human-caused climate change roughly doubled the likelihood of the hot, dry, low-humidity, windy conditions that drove this summer's major wildfires in Canada's Northwest Territories and northwestern Ontario. The study (not yet peer-reviewed, given how quickly this kind of rapid-attribution analysis is done) compared current conditions against a modeled world without the roughly 2.5°F of warming that's occurred since industrialization. The scientists involved specifically pushed back on President Trump's public comments blaming poor forest management, pointing out that lightning — not human activity — causes over 90% of the actual land area burned in Canada, and noting that much of the affected forest is remote, far-northern terrain that's inherently difficult to actively manage or quickly access in an emergency. Trump, for his part, has said directly that "if they managed their forests, they wouldn't have the fires," and has discussed the possibility of penalizing Canada over the cross-border smoke. Worth noting for context: this kind of dispute over climate versus management as the primary driver of wildfire severity comes up regularly with major fires in multiple countries, and mainstream fire and climate scientists generally point to a combination of factors — with the specific proportional blame remaining a genuinely researched, sometimes contested question depending on the individual fire and region.
