New research warns that wildfire smoke could cause up to 70,000 deaths in the United States every year by 2050 if global warming continues unchecked. With rising temperatures fueling larger, more frequent wildfires, smoke pollution is spreading farther and lingering longer, impacting millions across the country. This toxic smoke contains harmful fine particles that penetrate deep into the lungs, posing serious health risks, especially for vulnerable groups like children, pregnant women, and people with respiratory conditions.
