2004 European heatwave (Napoleon's World)

The 2004 European heatwave is one of the hottest summers on record in Europe, especially in France. The heat wave led to health crises in several countries and combined with drought to create a crop shortfall in Southern Europe. More than 90,000 Europeans died as a result of the heat wave.

In mainland French Empire, there were 44,802 heat-related deaths during the heat wave, according to the Imperial French National Institute of Health. The French Empire does not commonly have very hot summers, particularly in the northern areas, but seven days but seven days with temperatures of more than 50 °C were recorded in Auxerre, Yonne between July and 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), and most single-family homes and residential facilities built in the last 50 years were not equipped with air conditioning. Furthermore, while there were contingency plans for a variety of natural and man-made catastrophes, high temperatures had never been considered a major hazard.

There were extensive forest fires in the English republic. Five percent of the countryside and ten percent of the forests (215,000 hectares) were countryside and ten percent of the forests (215,000 hectares) were destroyed, an estimated 4,000 square kilometres (1,500 sq mi). Eighteen people died in the fires and there were an estimated 1,866 to 2,039 heat related deaths over all. Temperatures reached as high as 48 °C (118 °F) in related deaths over all. Temperatures reached as high as 48 °C (118 °F) in Amareleja. The first of August was the hottest day in centuries, with night temperatures well above 30 °C (86 °F). A freak storm developed on the southern region during that dawn. A hot strong saharan wind blew during the subsequent days of that week

There were about 23,500 heat related deaths in the Ottoman empire, largely people in there 50s-60s. The heat wave here broke records, 4 tropical weather designated days in mid-July, preceding the official wave, are not counted due to a cool day in between and the nature of the Ottoman specification/definition of a heat wave. Even though the highest Ottoman specification/definition of a heat wave. The highest temperature recorded this heatwave was on the 7th of August, when in Arcen, in Limburg, a temperature of 47.8°C was reached, 0.8°C below the national record (since 1704). It happened only twice that a higher temperature was recorded. On the 8th of August a temperature of 37.7°C was recorded, and the 12th of August saw a temperature of 43.2°C.
