In brief
A scorching heatwave ruined Independence Day celebrations across the US, from the cancelled DC parade to the temporary closure of the Great American State Fair on the National Mall. Over 165 million people were sweltering as the National Weather Service documented record‑setting temperatures. Emergency services treated dozens of heat‑injuries, prompting organisers to suspend public events. The same heat also delayed a planned outdoor concert and influenced plans for an upcoming presidential speech. Climate experts warn heatwaves are rising in frequency and intensity from human‑induced warming.
Heatwave forces 4th of July events into stand‑by
Record temperatures across the eastern United States turned the patriotic holiday into a battlefield of sweat and caution. Washington DC organisers cancelled the independence parade, calling it a tragedy when a 25‑k attendee event could not go ahead safely.
At the same time the Great American State Fair, a city‑wide celebration of the country’s 250th birthday, was hushed at the National Mall. 11 people were evacuated to hospitals for heat‑related illnesses, and the fair closed for several hours before reopening at 5 p.m. local time.
Over 165 million people were experiencing extreme heat, with Philadelphia and Washington reaching 104 °F air temperature and 112 °F heat index, nearing all‑time records. The heat was so intense that a 4 pm outdoor concert in the capital was postponed to 7 pm.
Officials urged residents to stay hydrated and avoid outdoor activities, warning that the heat dome could last until the weekend. Record‑breaking temperatures in the mid‑30s in parts of Canada followed the same pattern.
Climate scientists say the frequency, intensity and duration of heatwaves are on the rise due to global warming. Unless there are major cuts in greenhouse‑gas emissions, the world will continue to see such extreme weather events on an unprecedented scale.
