The Crises of Heat and Smoke Share a Common Thread: Climate Change
Human-caused climate change is making high temperatures more common and intensifying dryness that fuels catastrophic wildfires.

Between the dangerous heat baking Texas and the Southeast, and the wildfire smoke filling the skies throughout the Upper Midwest and into the Mid-Atlantic, people across a huge part of the United States have been seeking relief from the outside world in recent days.
The two threats this week aren’t connected directly. But a common factor is adding to their capacity to cause misery.
Human-caused climate change is turning high temperatures that would once have been considered improbable into more commonplace occurrences. And it is intensifying the heat and dryness that fuel catastrophic wildfires, allowing them to burn longer and more ferociously, and to churn out more smoke.
Climate change is “the elephant in the room” that is worsening wildfires and their effects on air quality, said John C. Lin, a professor of atmospheric science at the University of Utah. As this year’s Canadian blazes have shown, climate-related disasters are becoming international affairs, not just local or regional ones, Dr. Lin said."
