Concept
2003 European heat wave
Summary
The 2003 European heat wave saw the hottest summer recorded in Europe since at least 1540. France was hit especially hard. The heat wave led to health crises in several countries and combined with drought to create a crop shortfall in parts of Southern Europe. The death toll has been estimated at more than 70,000.
The predominant heat was recorded in July and August, partly a result of the western European seasonal lag from the maritime influence of the Atlantic warm waters in combination with hot continental air and strong southerly winds.
In France, 14,802 heat-related deaths (mostly among the elderly) occurred during the heat wave, according to the French National Institute of Health. France does not commonly have very hot summers, particularly in the northern areas, but eight consecutive days with temperatures of more than were recorded in Auxerre, Yonne in early August 2003. Because of the usually relatively mild summers, most people did not know how to react to very high temperatures (for instance, with respect to rehydration). Most single-family homes and residential facilities were not equipped with central air conditioning. While contingency plans were made for a variety of natural and man-made catastrophes, high temperatures had rarely been considered a major hazard.
The catastrophe occurred in August, a month in which many people, including government ministers and physicians, are on holiday. Many bodies were not claimed for many weeks because relatives were on holiday. A refrigerated warehouse outside Paris was used by undertakers as they did not have enough space in their own facilities. On 3 September 2003, 57 bodies were still left unclaimed in the Paris area, and were buried.
The high number of deaths can be explained by the conjunction of seemingly unrelated events. Most nights in France are cool, even in summer. As a consequence, houses (usually of stone, concrete, or brick construction) do not warm too much during the daytime and radiate minimal heat at night, and air conditioning is usually unnecessary.
