Chemnitz is burning: heat wave takes its toll on older people and is threatening again!

Chemnitz has the heat completely under control. According to the Free Press Maximum temperatures of 34.9 degrees were recorded in the city last Wednesday. In such moments, the risk is particularly high for particularly vulnerable groups, such as older people. Five seniors had to be admitted to Bethanien Hospital because of symptoms such as fever, dehydration and loss of consciousness.

It is already clear: global warming is also making itself felt in Chemnitz. More and more days with temperatures above 30 degrees are to be expected, with the city center particularly posing a challenge. Densely built-up urban areas like Chemnitz tend to retain heat for much longer than rural areas. In addition to heat stress, there is also the urban heat island effect, a phenomenon in which urban areas are a few degrees hotter than their surrounding areas, a circumstance that can sometimes be up to 10 degrees on summer nights, such as National Geographic describes.

The danger of heat islands

What happens in cities like Chemnitz when temperatures rise? The concrete and metal surfaces of our urban environment retain heat particularly well. Warm air builds up in taller, denser buildings and prevents you from cooling down at night. A further report from the city administration underlines this and states that the lack of open spaces such as parks and water areas exacerbates the problem as they are missing as natural cooling elements.

What is particularly alarming is that the large amount of sealed soil means that the rain cannot evaporate. Instead, it flows into the sewage system and is therefore not available for cooling. In addition, dark facades heat up the surrounding area even more quickly than lighter coats of paint. According to the city administration, the problem is compounded by an increasing use of air conditioning, which can locally increase the air temperature by up to 3 degrees, bringing additional heat stress to the city.

Approaches to improve the situation

The city of Chemnitz is working to meet the challenges posed by the heat. There is increasing emphasis on creating more green spaces, the targeted planting of trees and green roofs. Water sprays could also help lower the temperature during hot periods. Old trees play a key role here: their crowns can reduce the air temperature by up to 5 degrees and they store CO2.

As individuals, we also play our part in beating the heat. Watering trees and airing them out in cooler hours can make a small but significant difference. In addition, it is important that we always use environmentally friendly transport options.

The temperatures in Chemnitz will rise, and with them the challenges that climate change brings with it. It is in our hands to actively make a difference to improve the quality of life in our city. The future is getting hotter, and together we can make sure it stays more bearable.
