The compounding disasters are affecting millions across North America and Europe. In the U.S., wildfire smoke has led to hazardous air quality for 120 million people, while extreme heat waves have shattered temperature records, even in typically cooler regions like Montana and Minnesota. In Texas, flash floods have caused significant damage, with rivers and streams reaching near-record levels, trapping residents in their homes. In Europe, heat domes have turned landscapes into tinderboxes, leading to deadly wildfires and water shortages. These overlapping events are straining infrastructure, causing economic losses, and posing serious health risks, particularly for vulnerable populations (CNN, 20 Jul 2026).
