Companies are reporting a drop in business, reflecting the economic toll of the heat wave, which is lowering productivity and keeping shoppers at bay.

PARIS -- Europe sizzled in its first major heat wave of the summer on Tuesday, as Barcelona recorded its hottest June in over a century and the summit of Paris’ iconic Eiffel Tower was closed to visitors.

The heat was so expansive that mountaintops, including the French Alps, that are usually frozen from snowpack saw record temperatures. Heat records were set for June in Spain and Portugal.
