Extreme Heat Cancels a July 4 Parade as America Marks 250 Years

A dangerous heat wave forced the cancellation of an Independence Day parade in Washington, with about 160 million Americans under major or extreme heat warnings as the country prepared to mark the 250th anniversary of its founding, The Hindu reported, citing the National Weather Service.

The commemoration had a political dimension. Dawn reported that President Donald Trump used a speech on the eve of the anniversary to warn that American identity was under "renewed attack" from what he called domestic radicals and extremists, while praising American exceptionalism. The Pakistani outlet's framing emphasizes the combative tone of the address.

The disruption of a national holiday by heat is a small but concrete example of a recurring cost. When temperatures reach levels that make outdoor gatherings unsafe across much of a continent, the effects appear as canceled events, strained power grids and lost productivity, costs that accumulate season after season.
