As green spaces disappear, 13 00:00:47.340 --> 00:00:51.390 expanding cities lose the cooling effect of plants evaporating water. 14 00:00:51.390 --> 00:00:55.420 As a result, cities are often warmer than their surrounding areas. 15 00:00:55.420 --> 00:00:59.430 NASA scientists use thermal bands from satellites like Landsat and MODIS 16 00:00:59.430 --> 00:01:04.932 to understand how city layouts can affect the heat they produce.
