Urban heat islands (UHIs) are urban areas that have temperatures that are significantly warmer than their surrounding rural areas. By measuring the land surface temperatures within remote Artic UHIs and comparing to surrounding rural areas, it is concluded that even these Arctic UHIs are contributing significantly to climate warming. Some impacts of this are urban greening and declining soil stability. The first image shows a photo of a UHI in the Norwegian city of Tromso which allows us to see the more remote kind of urban area we are discussing here. Image 2 shows a satellite and thermal image of a UHI in Noyabrsk, Russia where we can see the land surface temperature difference between the urban area (red) and surrounding less urbanized areas (yellow and green). These images are extremely important because they serve as visuals for the audience to understand how drastic the land surface temperature change really is.
