Heatwave threatens: New AI model shows hot hotspots in cities!
Freiburg im Breisgau is using an AI model to precisely calculate heat stress by 2100 to enable urban adaptations.
Heatwave threatens: New AI model shows hot hotspots in cities!
Temperatures in German cities are rising and summers are getting longer and longer. A new AI model, developed by the University of Freiburg and the Karlsruhe Institute of Technology (KIT), can now calculate heat stress with meter precision up to the year 2100. This innovative model combines satellite images, weather data and geospatial information to create precise climate maps. Focus reports that such models are becoming increasingly important as cities look for solutions to adapt to rising temperatures.
Densely built-up urban districts that store heat and release it only slowly are particularly at risk. Current forecasts show that the number of hours with temperatures above 38 degrees could increase almost tenfold by 2099. In the worst case scenario, Freiburg im Breisgau could expect up to 480 hours per year above 26 degrees Celsius, compared to around 135 hours today. Tagesschau highlights that the model takes into account not only heat stress during the day, but also at night, where trees surprisingly tend to retain heat.
Adaptation strategies for cities
The need to adapt to the impacts of climate change requires increasingly creative and integrative solutions. Cities around the world, such as Copenhagen and New York, are showing with their innovative measures that climate-friendly planning is possible. By expanding green spaces and intelligent water management, urban areas can better deal with extreme weather conditions. Das Wissen describes that many cities are pursuing strategic approaches to increase their resilience to changing climatic conditions.
The use of the new AI model in urban planning could be crucial to enable specific heat warnings for vulnerable parts of the city and to effectively plan targeted measures such as tree planting and shading. With just one click, city planners can calculate the benefits of additional plants in a neighborhood and thus target heat-sensitive areas. The research is concentrated in Freiburg, but the model is flexible and could also be transferred to other cities.
In summary: At a time when climate challenges are becoming more pressing, it is time to focus on technological innovations and strengthen green infrastructures. Cities must plan wisely to maintain the quality of life of their citizens even in hot summers. The ball is now in our court – let’s keep our fingers crossed that the municipalities take the appropriate steps.
