Heat wave threatens health and the economy – billions in losses are looming!

Heat wave threatens health and the economy – billions in losses are looming!

Hot times lie ahead! On August 12, 2025, we will experience another heat wave that will severely affect not only the weather, but also numerous professional groups and entire industries. Roofers and hospital workers, among others, who face major challenges due to extreme temperatures, are hit particularly hard. How freitag.de reported that the weather services in North Rhine-Westphalia are measuring temperatures of up to 39 degrees. The heat not only poses a physical strain, but also leads to a significant increase in ambulance calls - up to 17% more than in normal summers.

The causes for these extreme conditions are diverse. Man-made climate change, particularly the increase in greenhouse gases from fossil fuels, industry and transport, is causing the frequency and intensity of such heat waves to increase. This is also further exacerbated by changing atmospheric circulation patterns and urban heat islands, as noted klima-wissen.de is explained. The heat-related risks are enormous: from circulatory failure and dehydration to premature births and surgical complications.

Economic consequences and infrastructural challenges

The economic impact should not be underestimated. Loud t-online.de could cost the European economy up to 240 billion euros annually by the end of the century, which corresponds to around 1.9% of economic output. Infrastructures are also affected; In July 2018 there was severe damage at Hanover Airport, where the heat caused the runway to crack. Roads are also showing large cracks due to the high temperatures, leading to an increase in “blow-ups” on the highways.

The pressure on agriculture is also enormous. Hot spells are driving up water shortages and making irrigation difficult, while crop failures are driving up food prices. In the long term, the wood processing industry will also suffer, as trees will have to be felled earlier and the quality of the wood will suffer, experts note.

Call for adaptation and support

The Construction Association is vehemently committed to urgently needed adjustments, including an extension of seasonal short-time work benefits to the summer months. In order to help particularly vulnerable groups, such as homeless people, Diakonie is calling for more support, for example by providing water and so-called “heat buses”. In addition, companies need flexible working hours and air-conditioned break rooms to enable their employees to work more comfortably.

Overall, sustainable adaptation strategies are required – from greening cities to creating heat-resistant tree species. How on klima-wissen.de As is emphasized, Europe has the potential to take on a pioneering role in climate protection. Open discussions, education and a sober approach to the topic are crucial. Only together can we face the challenges of the future.
