Urban heat island. Thermal satellite image of Buffalo, New York, USA. Colours indicate surface temperatures, with dark blue coolest, through purple to orange and yellow (hottest). This phenomenon occurs in built-up areas where concrete and other surface materials retain heat for longer than rural areas covered in vegetation or bare ground. Image obtained by the Enhanced Thematic Mapper on NASA's Landsat 7 satellite in August.
