The study looked at how cities in Qatar are getting hotter due to urban growth. By using satellite data and ground measurements, researchers found that Doha city has been getting warmer at night over the past 30 years. The city has also expanded a lot during this time. Temperatures in Doha are higher than in other areas, both during the day and at night. The increase in heat is linked to the city's growth. To cool things down, it's suggested to use energy more efficiently, create more green spaces, and use reflective materials on buildings. These findings can help plan future cities in a way that is better for the environment.
