How is the heat wave in Rio de Janeiro affecting Carnival preparations?

The heat wave struck Rio de Janeiro less than two weeks before Carnival, directly impacting construction workers who are currently assembling the festival's installations. Despite the extreme temperatures, Rio's mayor Eduardo confirmed that the city would not cancel any Carnival events, which attract millions of tourists and serve as a major revenue source for the city. The timing of this extreme weather has raised concerns about the smooth running of the festival, though officials appear determined to proceed with this economically significant celebration.
