The extreme heat, high winds, and severe dry conditions that produce towering, fast-moving flames that advance by the acre are not just becoming more common; new research shows that these factors are increasingly arising in multiple regions at the same time, creating the conditions for simultaneous wildfires around the world.In a study published in the journal Science Advances, researchers reported that the ideal conditions for major wildfires are now aligning across different parts of the world at more than double the rate they did nearly 50 years ago. Climate change is a major driver, accounting for about half of this increase. It’s the latest example of how humans are reshaping the nature of wildfires.These changes have led to periods of inescapable smoke from blazes and more stress on firefighters, expanding the public health, economic, and social costs of infernos. As the climate continues to warm, these trends are likely to continue to worsen.AdvertisementAdvertisementWildfire smoke is already linked to tens of thousands of premature deaths in the U.S., and recent years have shown how this smoke can cross continents and oceans, polluting the air for people far away from the flames. East Coasters might remember how Canadian wildfires a few years ago bathed cities like New York and Philadelphia in an amber haze, triggering air quality warnings. One study found that the smoke from those fires contributed to 82,000 deaths.Meanwhile, the efforts to contain these devastating blazes are devouring money, time, engines, tankers, and firefighters, often beyond what local fire departments can muster on their own.But with more wildfires burning in different parts of the world at th …
