About 70 million people in the U.S. are facing excessive heat advisories due to a significant “heat dome” affecting southern and central states. Temperatures are expected to range from 95-105°F (35-40°C), with some desert areas possibly reaching 120°F (48°C). This heat dome, a high-pressure system, traps heat and is forecasted to continue into next week.
While heat waves are typical in summer, their increased frequency and intensity are largely attributed to climate change, driven by human-induced greenhouse gas emissions. This summer has already seen cancellations of events due to heat, with record temperatures hitting areas like Montana.
The National Weather Service has issued heat warnings, particularly in western Nebraska, where temperatures could peak at 108°F (42°C). Extreme heat is notably dangerous, especially for vulnerable populations such as the elderly and those with health issues.
Similar heat conditions are affecting Europe, with thousands evacuated due to wildfires in Spain and France, highlighting a global trend of rising temperatures and increased fire risks. Climate experts predict that ongoing changes will lead to more severe heat waves and higher nighttime temperatures in the future.
