🔴 #THISISCLIMATECHANGE. 🔥Canadian fires—sending smoke into the Northeast U.S.—sparked in extreme heat, 20°F+ above average, made at least 3x more likely by climate change. 🌡️ 53M people in the U.S. Southwest & Mexico are facing extreme heat nearly impossible w/out it.🧵/6

Climate change is driving more frequent and intense fires—and that’s stalling or reversing decades of air quality progress in the U.S. Since 2016, 30 states have seen this trend, with the biggest setbacks in California, Oregon, and Washington. 🧵/5

More fire weather days = more wildfire smoke days. Even if the fires are hundreds of miles away, the smoke travels—and doesn’t stop at state or national borders. 😷 PM2.5 particles can reach deep into lungs and even the bloodstream, worsening respiratory and heart health. 🧵/4

While 87% of U.S. wildfires are sparked by human activity, climate change sets the stage. 🔥 Hotter, drier, windier days—aka “fire weather”—are now more common, especially in the West. Some areas have added 25–55+ fire-risk days per year compared to generations past. 🧵/3

As of Thursday (Aug. 7) morning:. 🔥~500 active fires were burning near 2M acres in the United States.🔥730+ fires were burning in Canada. with nearly 500 of those listed as "out of control". Thick smoke from these fires is being lofted through the Lower 48.🧵/2

Wildfires continue to burn across parts of the U.S. and Canada again, and air quality has dropped from "moderate" to "unhealthy" again for millions of Americans Thursday (lasting through the weekend). Here’s a quick 🧵 on how climate change is part of the smoke story 🔽

Burning fossil fuels creates heat-trapping pollution as well as air pollutants, both of which can worsen air quality and put health at risk. #climatematters

This is an area that knows heat. But even then, it's hotter than it otherwise should be. A key indicator that things are out of whack? Check out how much more often heat records have been getting set than cold. #ThisisClimateChange.

Dangerous heat is headed for the Southwest and northern Mexico this week with temperatures up to 18°F above normal in some areas. Climate Shift Index levels of 5 indicate that human-caused climate change made this heat at least 5x more likely.

Extreme, climate change-fueled heat is increasing fire risk and challenging existing firefighting efforts as wildfires continue to burn across Spain and Portugal.

#ThisisClimateChange Temperatures this week are forecast to be up to 15°C (27°F) above normal across Portugal, Spain, and France, with Climate Shift Index levels reaching 5 — indicating the heat is at least 5x more likely due to human-caused climate change.
